Manufacturing execution system capabilities

MES solutions replace traditional paper-based manufacturing procedures and implements a proactive approach to manufacturing execution. Sometimes manufacturers implement reporting functionalities that fall within the scope of MES and sometimes a full-scale MES solution is integrated across the entire plant. Regardless of the size of the solution, the results of implementing MES include decreased costs and increased support for continuous improvement and lean initiatives. MES is used in conjunction with ERP and SCADA systems, bridging the daily plant operations to the rest of the business. Manufacturing Execution Systems can tie into existing batch management systems, such as BatchLOGIX®, and use the existing inventory and production information to give further insight into yield and production metrics. MES connects existing ERP systems, PLCs, and databases. The combined data from those sources can create unique metrics, reports and dashboards that streamline operations, improve productivity, and ensure quality. Using a versatile platform like Ignition Perspective, the capability exists to connect all those data sources, create flexible dashboards, custom reports, custom modules, and Ignition's platform is designed for mobile access. REAL-TIME DATA MES platforms provide real-time production information. This valuable information opens the door for quick production snapshots. Dashboards combine real time operating rates and statuses with features like historical run information and production goals. Doing this provides an efficient way for a user to quickly see production status and identify areas that need attention. HISTORICAL DATA With comprehensive access to plant-wide data, MES offers extensive reporting capabilities. This is another area where the Ignition platform is helpful. Leveraging Ignition's Reporting module, information can be gathered from all the different data sources (ERP, Control System, and SCADA) allowing for the creation of tailored reports that effectively convey data for analysis. Through Ignition's broad array of device drivers, information from data from all parts of the plant can be logged and displayed in a central location. Additionally, the Ad Hoc trending tool proves to be a valuable asset, facilitating easy trend analysis of data points from all sources and saving those trends for later analysis. PERFORMANCE ANALYSIS Centerlining includes adjustable thresholds for each device set the acceptability and alert levels for each indicator. Selected KPIs (key performance indicators) such as Right first time (RFT), Rework, Scrap, Process capability (Cpk), and Overall equipment effectiveness (OEE). With one click, the dashboard can provide a detailed analysis of causes of shutdowns and rejects, batch quality rates, and other production indicators. COMMON MES FEATURES With all this data, both real-time and historical, there are many different modules that can be implemented. The goals and priorities of each plant and workstation guide which modules should be implemented or if a custom module needs to be developed. Below is a list of common modules. Scheduling Provides a global view of the planned production orders. This module can include changeover information, anticipated production time, equipment and materials needed with specific job details to complete the order. Work In Progress (WIP) Inventory Management Track and manage inventory through the different stages of production. MES accomplishes this by helping management fine-tune forecasting by providing real-time inventory audits. With the connection to the ERP system and the control system, validating the inventory levels between the two systems is now automatic. This eliminates the need to manually verify inventory levels on the production floor with what is on the books. The system can also verify materials will arrive in time to complete orders by looking at the delivery data on purchase orders and running it against the upcoming production schedule. Recipe Management A recipe consists of a list of ingredients, ingredient amounts and sequence for combining those ingredients, and the amount to be made (batch size). Create consistency from product to product and run to run as well as make the best use of resources to minimize waste and streamline the manufacturing process. Production Tracking and Dispatch Manage the bidirectional flow of production data in real time between the ERP and the plant floor. Lot Tracking and Tracing From raw material receiving through final product, lot numbers are traced throughout the entire production facility. MES allows for quick recording of batches of raw material, semi-finished products, and finished products, utilizing product genealogy which tracks raw materials, equipment used, dates, quantities, lot, and serial numbers. Quality management and Control Manage the quality of manufacturing processes and units including quality deviations and exceptions. Integrate quality check reminders and recordings for QA. These can be as automatic as implementing density and moisture sensors or more manual with an alarm signaling the operator to complete quality assurance (QA) checks and record them in the system. Each records the information to the MES system for the QA team. Preventive Maintenance Optimize the planning of preventive maintenance operations to reduce the impact on manufacturing. OVERCOMING COMMON CHALLENGES TO IMPLEMENTING MES Implementing a Manufacturing Execution System is a large undertaking and to provide the best solution, collaboration between the integrator and the manufacturer must be frequent. A common challenge is providing the right information and tools to the right audience. When developing dashboards and reports, it is very important to remember who is using the feature and what the goals and priorities are. An operator will want to see different metrics and widgets than someone in a management role. When developing dashboards and reports it is very important to remember who will be using the feature. Separate dashboards for different groups can be created, or widgets can be dynamically hidden/shown depending on the log in permissions and who is viewing the application. Often facilities have used multiple integrators and software systems throughout the plant. This poses a challenge to gathering data in an accurate and efficient way, as there are a variety of sources. NorthWind maintains consistency wherever possible and keeps documentation on where metrics are pulled in from. Documentation is available straight from the MES project. The user can see a description of how a widget works and where the information is being pulled from, whether it is from BatchLOGIX database, a customer's existing ERP system, or a PLC Program. A key to overcoming these challenges is to have open and effective communication with plant personnel to ensure there is clarity on what information is needed. This starts with setting a detailed scope for each area of the system to avoid unnecessary and potentially costly distractions. NorthWind provides a detailed design/development/deployment process and holds meetings with the customer throughout each stage to discuss the project progress and steps to be taken to reach the next stage. Manufacturing execution systems identify inefficiencies and optimize production. This powerful system can be everything from Overall Equipment Efficiency (OEE) for one area of a plant to a fully integrated solution with a paperless plant floor and everything in between. Implementing these features takes deep process and control system knowledge and because every plant has different processes, machinery, KPIs, and process targets the best solution is going to be a tailored fit. At NorthWind we utilize production and process data for plant optimization with a manufacturing execution system developed for you, with you. Learn more about NorthWind's MES Solution.

Formula management software for pet food production

Automation streamlines the manufacturing process and allows manufacturers to easily monitor and make modifications to the production process from anywhere. Implementing good formula management software gives manufacturers product consistency, lot tracking, and production reports, and it can be easily integrated with ERP (Enterprise Resource Planning) software for a seamless solution. Importance of formula management Implementing the right formula management software is key to maximizing plant performance. This software manages and stores all the formula information for the plant, as well as important process information for lot tracing and production analysis. This includes raw material delivery and storage, final product storage, mapping materials throughout the entire process, and important batch, campaign, and ingredient usage details. It is worth spending time researching formula management software to ensure the package implemented aligns with your business needs. Common Features • Create and store recipes • Recipe modification • Ingredient location mapping • Ingredient parameters • Lot tracking • Production records • Campaign Management Manufacturers often use several software packages to have these features and encompass all processes within the plant. When looking at a system that can fully handle all production needs, features, additional advanced features are needed. Advanced Features • Recipe modifications from the HMI • Ingredient location mapping • Process variables • Micro-ingredients and micro-batching management • Integration with ERP and MES (Manufacturing Execution System) software • Capability of handling both batching and continuous processes Formula management software, such as NorthWind's BatchLOGIX®, provides all the common and advanced features in one robust platform. With features such as material mapping, recipe creation, process variables, micro-ingredient tracking, and production reports, it's able to fulfill production demands. NorthWind offers additional integration that connects the plant floor to the rest of the business. By integrating with the plant's ERP system, data continually transfers back and forth from both systems for seamless and high-level business management. Formulas Formulas for pet food production are complex and need a robust piece of software to handle all variables and both batching and continuous processes within the plant. Often recipes only refer to the amount of each material needed, but there is a lot more that goes into establishing product consistency than simply ingredient amounts or weights. To produce a consistent product, formulas should include both ingredient and process variables and the entire production process from micro-ingredients through continuous extrusion. Ingredient Parameters Ingredient parameters include setpoints, rate tolerances, and upper and lower setpoint trim allowance. Setpoint is the target ingredient rate, tolerance is a percent of error acceptable, and trim allowance is the amount that the setpoint can be adjusted by the operator during production. For example, an ingredient has a setpoint of 100kg/hr, tolerance at 10%, and a trim allowance of 10kg/hr. The operator could adjust the ingredient rate and call for 110kg/hr. The actual rate could potentially be 121kg/hr and still be within the acceptable tolerance. Process Variables Process variables are all the mechanical setpoints on the production floor. For example, a few of the extruder's common process variables include Head Temperatures, Die Temperature, and Die Pressure. These variables are critical for complying with quality standards, making them a vital piece of the formula. Micro-ingredients Batching Hand-batched micro-ingredients are important and often high-dollar ingredients that play a significant role in the final product. This part of the process is often handled separately from the formula management software. Because this step is not included in the formula management and plant automation system, errors often occur during the weighing and lot tracking of these ingredients. BatchMATE® by NorthWind connects the hand batching step to the rest of the plant by automating the hand batching process and including the steps in the formulas. Once connected, BatchLOGIX can track the lots and produce production reports. Lot Tracking Lot Tracking is one of the most critical aspects of any Formula Management Software. The lot tracking process starts from the receipt of raw materials through the final product. By tracking lot numbers in this way, the system can pull specific lot information for each campaign and batch. This is invaluable when a non-compliant lot or a major fault is detected by the quality department. Using the information provided by the lot tracking feature, production data can be analyzed, and contaminated ingredients and products can be identified, isolated, and pulled from the batch or campaign. Production Reports Production Reports are key for any Formula Management Software. The information provided in these reports helps in scheduling production and can be helpful in identifying the cause of missed targets and other inefficiencies. Production reports can also identify when to schedule maintenance and other necessary stops for production. Ingredient usage and run reports are also available to ensure quality and production targets are being hit. Some of the key benefits of good production reporting are business insights, higher customer satisfaction, higher efficiency, and better data-driven decisions. ERP Integration Integrating the plant floor with the rest of the business allows for production data to be seamlessly used throughout the business. It is common for APIs (Application Programming Interfaces) to be written for connecting the plant floor to the ERP system. Having the ability to share data between the different systems is a huge advantage to companies, with this they can schedule production and analyze production in real-time. When all the data is readily available, business decisions are now easily backed by data. Conclusion Whether scaling recipes into a batch or metering ingredients into a continuous system, quality formula management software is key to maximizing plant performance and increasing product consistency. BatchLOGIX® has the scalability to accommodate systems of any size with the flexibility to incorporate all processes within a pet food production facility.

Successful control system modernization

The most obvious illustration of this is systems that have obsolete electrical components and legacy software that is no longer actively supported by original manufactures. As we move into Industry 4.0, the old standard of each individual machine having an isolated 'island' of automation is being replaced by more integrated automation systems that communicate to each machine, sharing and creating significantly more data than even 15 years ago. With this added data is the desire to connect the plant floor data to business systems. More and more facilities want production orders to come down from ERP systems to process controls, producing real-time consumption data that is utilized to reduce inventory. To stay competitive, many facilities have made the business decision to modernize their legacy machine and controls systems. Typically, this can be done at a fraction of the cost and time of a greenfield project. Modernizing a control system A control system upgrade can bridge all these gaps by integrating mechanically sound process systems with a modern automation system. At a minimum these projects consist of substantial replacement of obsolete components, sometimes even retaining the original PLC logic. These projects can also be expanded to include high level integration of different machines, adding new machines to an existing system, ERP integration, and ground-up re-writes of logic and operator screens. Modernization projects are known to be complex, especially because engineers are required to work inside an existing framework as opposed to building a system from the ground up. There may be missing documentation or drawings. Additionally, some field modifications may not be included in the drawings. Minimizing production downtime is a significant concern, so the implementation window to get the system back in production is often small. A successful modernization project considers these factors and others during the initial phases of the control system upgrade. Key to any project is developing a deep understanding of the existing system. This is paramount to implementing the upgrade without breaking what is currently in place. Best practices As a Senior Project Manager at NorthWind, I have implemented many modernization projects throughout my career. In this time, I have found a few tried and true practices that lead to a successful control system upgrade. Customer/Project Management Planning When modernizing any system, a collaboration between customer and Project Management is a must. Through this collaborative approach, a forward-looking plan is made to include functionality, risk avoidance, down time reduction, migration solutions, project phasing, etc. to ensure the project scope is clearly outlined and understood. Design Trip There is a misconception that modernization will 'break' the current system and lead to significant downtime. Conducting an initial design trip is instrumental for designing a project that takes into consideration the existing system and its functionality and designing a system that will meet the customers scope and needs. Before any modernization takes place a review of pre-existing equipment, electrical, design and functionality is conducted. Any existing drawings and documentation are also thoroughly reviewed. In the event there are no drawings of the existing system, a new set will be created. Safety Considerations There are misconceptions involving safety considerations: Many people think that safety guidelines are grandfathered in by the date of the original mechanical equipment installation. However, on any substantial electrical modernization project, safety circuits and functionality need to be reevaluated. Electrical Installation One of the biggest concerns with control system modernization is the amount of time it will take for installation and requalification. Working with an industrial electrician with the expertise to understand how to work within schedule constraints and provide creative, custom solutions to meet outage windows is critical. Installation can be done in phases, during production downtimes, or any other number of solutions to keep downtime at a minimum. Benefits of modernization Updating hardware and software with better automation control systems can improve plant performance, increase productivity, improve communication between the process information and business systems, provide useful production data, provide alerts to improve response times, increase plant system security and perform system diagnostics. With NorthWind you can achieve an effective modernization project that manages safety, health and environmental risks, get documentation for field devices in the system, and be assured of a more efficient, consistent and optimized operation, with the support of the system for years to come.

Remote access for industrial control systems

This tool is particularly helpful in servicing control systems through a network connection. By connecting to the system's programmable logic controllers (PLC), Human Machine Interface (HMI), and other Ethernet compatible devices, integrators can efficiently monitor, troubleshoot, and fix an issue without physically traveling to the site. Employers can control many quality services via remote access, such as: troubleshooting, remote startup, remote monitoring, software upgrades or additions, proportional-integral-derivative (PID) tuning (adjust the PID controller), User Interface (UI) additions, and other improvements to the customer's automated system. Service technicians have access to tools and software solutions that many manufacturing plants may not have, and these can be utilized remotely to enhance the service experience. This article discusses best practices for establishing remote access, services provided using a remote connection, and help determine if remote access is correct for your plant. Best practices for establishing Remote Access When establishing remote access to a plant's control system for the first time, there are several guidelines to follow from both the integrator and the plant's side. The first step to connecting remotely is to obtain permission from the plant's IT department to access the virtual private network (VPN). The integrator provides the plant's IT department with a list of authorized technicians who will provide service and support for the plant. The plant's IT department will set up user accounts for those authorized technicians. If applicable, non-disclosure agreements will be signed. Safeguards for a secure connection Integrators use a VPN for connecting to the plant's control system Plant IT has an isolated network for the VPN Routine system backups Utilize virtual machines (VM) Remote Access – Technical Service and Support A major benefit for establishing remote access to a plant's control system is the ability to quickly be connected for service and support. In the event there is a problem with the control system, such as a production sequence is out of order, a burner is not reaching a high enough temperature, or a conveyor is not moving fast enough, plant maintenance personnel can contact an integrator for technical support. A service technician is speaking directly with the plant personnel. By working together, problems are solved faster, immediate feedback is provided, questions or concerns are addressed, and this is an opportune time to provide plant personnel some system training. With remote access available, service technicians are able to support plants quickly and efficiently. With prior remote access established, a technician can be connected to a plant within 15 minutes of calling about an issue. This quick connection time allows for troubleshooting to begin immediately, while reducing plant down-time. Remote access allows the service technician to monitor the system live to catch any intermittent problems. Control Systems can be remotely accessed and watched for a specific problem or issue over a number of hours or days. Then when the problem occurs, the service technician can isolate what caused the problem, what conditions were present when the issue occurred and provide a solution. Another benefit to remote access is being flexible within the time frame of system maintenance. Service can be provided around rigid time and production schedules, as remote access can occur at any time during the day. This eliminates waiting until regular business hours to contact support and then having to make travel arrangement to get a technician on site. Remote access can also serve as an extension of the customer's maintenance and continual improvement departments. Remote Access – Control System Startup Some Control System modification and addition projects can be started up remotely. The benefits to a remote startup are similar to remote access service. Time (travel and onsite) Money (costs of travel, rental, accommodations, etc.) Resources Help can be offered immediately, the customer only has to pay for labor time to fix an issue, fixes can be provided around rigid production schedules, and additional resources can be utilized. Remote Access can also be used in conjunction with onsite startups to provide additional training and which helps build on more complex ideas and unique operating situations. And lastly, with the restrictions of travel and health concerns surrounding Covid 19, quarantine restrictions and safety protocols can be eliminated if remote access is used. Remote Access can provide a quick, affordable solution for control system maintenance. Remote Access saves travel time, accommodation costs, and costs associated with down-time. Remote access provides the customer with immediate help and resources any time day or night and remote access can also be used to monitor intermittent problems. Remote Access can be utilized not only for start-ups, service, and maintenance, but operational training as well.

Benefits of modern batching systems

Batching systems play an important role in product quality and plant efficiency for pet food and treat processors. Equipment design can ensure product uniformity, consistent product flow, and efficient changeovers from batch to batch. There are a number of common options for batching systems in pet food and treat applications, and processors must consider several factors when looking to upgrade their facilities. Evaluating batching systems 'When considering an automated batching system for pet food ingredients, it is important to look at several factors which will influence the type of batching system recommended and optimize ingredient cost savings and overall ROI,' said Sharon Nowak, business development manager, Coperion K-Tron USA Food & Pharmaceutical Industries, Sewell, N.J. 'The top three for consideration include batch accuracy required for the specific ingredient, desired batch times, and overall plant design considerations including height limitations, space requirements, and support structures for the batching system.' 'It's a little different for everyone,' added Matt Lueger, vice president of sales, NorthWind Technical Services, Sabetha, Kan. 'But the big factors that we typically see are accuracy, traceability and flexibility. Most customers not only want a system that consistently produces a quality product, but also tells them what went into each batch without restricting their ability to continually change their ingredients or recipes.' Pete Ensch, chief executive officer, WEM Automation, LLC, New Berlin, Wis., agreed on the importance of traceability for today's processors. 'The batch system needs to incorporate lot code traceability,' he said. 'Pet food producers' value is directly linked to their track record of producing safe quality food. In the event that something goes wrong, you need the ability to quickly track the problem and contain it. Traceability needs to be automated and working in the background. Beyond the safety side, traceability also helps to control inventory management and control, and can be linked back to your ERP to help automate purchasing. This keeps production flowing and controls cost.' Other factors to take into consideration include throughput, types and quantities of product that need to be conveyed, and quality and repeatability. 'At the end of the day, you need a batching system that can accurately weigh out your ingredients and consistently mix them,' Ensch explained. 'Pet food has some unique challenges in that there are many different ingredients with a variety of densities and flow rates. Several of the raw ingredients, because of the nature of protein, have a significant amount of variability. Equipment and controls need to be able to handle the de variety. All of the downstream processes like extrusion and drying perform better if you provide them a consistent, quality input.' Batching options Modern batching systems are designed with factors such as accuracy, reliability, traceability, flexibility and food safety in mind. 'Due to the increased food safety regulations and requirements to adhering to exact ingredient percentages in a given pet food recipe, the use of high accuracy LIW [loss-in-weight] batching using gravimetric screw feeders is quickly becoming the most reliable batching device of choice,' Nowak said. 'LIW batching utilizing Coperion K-Tron high-accuracy screw feeders provides a significant accuracy and process time advantage over traditional GIW [gain-in-weight] batch techniques. LIW batching is used when the accuracy of individual ingredient weights in the completed batch is critical or when the batch cycle times need to be very short. In addition, LIW feeding affords broad material handling capability and thus excels in feeding a wide range of materials from low to high rates.' Regardless of feed rates, LIW batching can offer accuracy, speed and variability benefits over traditional GIW methods. (Source: Coperion) 'There are several different types of batching systems,' added Joe Lewis, marketing, Sterling Systems & Controls, Inc., Sterling, Ill. 'These include semi-automatic hand prompt/add batching systems, semi-automatic self-contained 'kitchen type' batching systems, and automatic batching systems.' Utilizing different systems and features allows pet food and treat processors to fine-tune the batch process from start to finish. Options include manual or automatic batch delivery, various ingredient storage methods, and integration to the ERP system to communicate production schedules and ingredient usages. 'Most modern batch controls have dozens of features, but a couple of useful ones for pet food are an order grid and automatic bin level checking,' Ensch said. 'An order grid includes order number, formula name, the amount of material to be produced, the required date, destination bins and comments. The grid can have orders entered direct or interfaces with your ERP system. Automatic bin level checking has the system check bin levels of each ingredient in a production run prior to starting the batch. The system will alert the operator of any insufficient ingredients. 'Another useful feature is production usage tracking and inventory management with lot code tracking,' Ensch added. 'This allows the batch system to track material used for each production run, batch, and track respective lot codes for ingredients. Statistical process control (SPC) charting is one more feature that's great for fine-tuning the batch process. A system tracks the production data to the level to produce statistical process control charts. Being able to understand when a system is in control or out of control and having the data to either troubleshoot it or reduce variation for greater accuracy can change your business.' Product quality There are several ways in which batching systems can impact product quality. 'Vacuum conveying systems help to provide the right amount of ingredients or final products to the next processing or packaging step,' said Andrea Bodenhagen, communication and content manager, Piab Vakuum GmbH, Butzbach, Germany. 'Thanks to the closed system, it also provides a dust free environment and protects the product from contamination. While the pet food industry is often still using mechanical or manual material handling, vacuum conveying systems are state of the art in the pharma and food sector. Pet food manufacturers, therefore, benefit from the long-term experience of Piab in these sectors as well as all the developments that have been done for these industries to keep the original product quality during the conveying process.' 'Batching systems play a significant role in the overall product quality of pet food and treats,' Lueger said. 'Not only in the accuracy and consistency of the ingredients that make up the product, but also in the visibility of what went into the product in the event of a quality issue. Batch reports and historical trends can go a long way toward preventing future product quality issues.' Jim Gaydusek, sales director, United States and Canada, Cozzini LLC, Chicago, agreed that batching systems have an important role to play in consistency and product quality. 'One of the greatest benefits is consistency from batch to batch,' he said. 'Auto management of recipes removes much of the human factor and reduces processing error. Scales accurately weigh the ingredients to ensure the proper weight(s) get added and the HMI [human-machine-interface] can sequence through the processing steps according to the program.' Plant efficiency Batching systems can also impact plant efficiency for pet food and treat processors. 'In addition to improving product quality over traditional manual weighing methods, the automation of the material handling/product transfer as well as the batching can greatly affect overall efficiency,' Nowak said. 'The use of automated dispensing systems, which can also integrate pneumatic conveying systems for material transfer, can greatly reduce the amount of human interaction as compared to manual methods of weighing and transfer. This maximizes social distancing and adheres to strict COVID guidelines of safety. 'Properly weighing and accurately delivering the ingredients without manual intervention can result in a number of process advantages, including overall food safety, fewer mistakes, better accuracy, lower bulk costs, improved product quality and savings in manufacturing costs,' he added. 'Eliminating manual batching reduces scrap costs, increases efficiency and throughput,' Lewis noted. 'Automatic systems can be customized with multiple scales for speed of batch production without sacrificing accuracy or quality, resulting in fast high batch rates and accuracy of weighments. Dust containment and collection options for automatic batching systems improves safety and operator efficiency.' Processors must be able to track and trace each ingredient throughout the process to ensure quality and safety and, in the case of a product issue, pinpoint exactly where and what went wrong. (Source: Coperion) To maximize overall efficiency, factors such as system design and sequencing must be taken into account. 'You want a system that moves from one batch to the next seamlessly and with little idle time between batches,' Ensch said. 'Some of this is system design, things like having holding vessels, surge bins and multiple scales so that you can weigh up ingredients before the mixer; optimizing cleanout times between batches and changeovers; the use of high and low bin level indicators and automated routing to make sure the batching system is never starved for ingredients. The system must manage all the timing, so the batching process is nearly continuous in nature.' New advancements Batching systems continue to evolve to meet changing needs and requirements. Modern batching systems now have huge advantages over their predecessors in a multitude of areas. 'Over the past decade the number of different types of formulations and the raw ingredients used has grown exponentially,' Ensch said. 'This has made batching systems larger and more complex. Having a blending control system that has formula-based scaling and mixing parameters is extremely helpful. The trend of higher protein pet food has also increased the content of fibrous protein ingredients, which have the much greater variation. Formulations contain many ingredients and there is a need for a batch system that can measure major, minor and micro ingredients with very low dispersions like vitamins and minerals.' 'There have been a significant number of design improvements to batching systems for pet food and treat processing,' Nowak said. 'They include improvement in weighing technologies and batching controls, improvements in overall design of equipment to improve cleanability and food safety while minimizing downtimes, improvements in feeder design options ideal for difficult flowing materials, and improvements in feeder technology to alleviate pressure/vacuum influences on the feeder output.' Advancements in technology have also vastly improved traceability of ingredients. 'The amount of technology that is utilized to track and trace ingredients continues to evolve,' Lueger noted. 'From simple bar-coded lot numbers on bags to RFID [radio-frequency identification] tracked totes/IBCs [intermediate bulk containers] and hoppers on tracks or AGVs [automated guided vehicle]. Innovation and technology gains continue to support traceability regardless of size, equipment configuration, system capacity, etc.' By Richard Rowlands & Matt Lueger Northwind Technical Services - Pet Food processing

Identifying critical system data with High-performance graphics

The control system's human machine interface (HMI) is the connection between an operator and each machine. HMIs provide processing data for operator and maintenance personnel to interact with the equipment. Traditional HMI graphics that are full of color, moving components, and detail are visually impressive but inefficient as the colors and animations detract from the actual data needed. Plant operators and maintenance personnel must quickly identify critical process information and high-performance graphics (HP graphics) allow them to do just that. By understanding HP graphics and how they help operators identify critical information, companies can confidently make the shift to new technology. High-Performance graphics vs traditional HMI graphics: Visual Differences HP graphics reduce troubleshooting time by highlighting pertinent information. While maintaining a visual representation of the equipment and system, HMIs provide a user with helpful alerts and status information. In traditional graphics, the proliferation of color is distracting. HP graphics reserve bold colors and movement only for instances when attention is needed. For example, if a receiver refill is disabled and the receiver is below low level, the low-level indication is visible, but the banner will be gray instead of yellow. This color change allows the operator to better focus on critical information. How to transition an HMI to HP Graphics It's possible that some personnel will not be initially accepting of the new graphics. The biggest push back when upgrading to HP graphics generally comes from operators that have been working with traditional HMIs for a long time and are used to a lot of color and detail on the screen. The grayscale color scheme brings a misconception that the new HP graphics will make it harder to understand what is happening in the system. However, with more muted tones, alerts and warnings are very easy to spot, providing the user a very readable HMI. HMI alerts and alarms that benefit from HP graphics include: System Status Device Faults Low Feed Rate Ingredient Setpoints Trends Process Variables Batch Details Implementing HP graphics on the plant floor NorthWind has moved to HP graphics as a standard for all projects. With this change, we have maintained the same overall feel, while providing a more readable HMI. Our HOA banners, menu bar, and feed point objects maintain similar aspects to our old graphics package but are now more visible when data is most critical. A lot of the changes incorporate the intentional use of color and adding dynamic visibility – displaying exactly what information the user needs to see at the critical moment. To further ease troubleshooting, reference points are built into the HMI, PLC, and electrical drawings, allowing personnel to quickly find the information they need. NorthWind trains and supports customers through the transition to HP graphics – from the startup process to complete integration. We also transition existing HMIs to HP graphics for a streamlined user experience across the entire manufacturing plant. At NorthWind, we're all about data. The efficiencies gained with the new graphics are everything we're about – accurate process data in the most usable form. Source: Northwind Technical Services LLC
