“If you fail to plan, you are planning to fail”. This quote by Benjamin Franklin emphasizes the importance of site surveys for industrial environments. With time, money, and resources on the line, site surveys act as a crucial first step to plan for maintenance, spare parts, upgrades, and mitigate the risk of unplanned downtime. This critical information was needed by a leading American food distributor to better understand the health of their plant’s automation infrastructure. E Tech Group was engaged to thoroughly assess their automation hardware and operational technology (OT) networks and provide a comprehensive site assessment report. This report would clearly identify risks and opportunities as well as crucial steps to upgrade and strengthen their automation infrastructure.
Solution
The customer’s plant had three buildings which included over 500 control panels. E Tech Group analyzed numerous factors and data points to determine areas of risk and opportunity across their plant. This included the lifecycle of parts that are currently being used on the production floor as well as the equipment’s life cycle positioning ranging from active to end of life. E Tech Group’s certified professionals also evaluated existing processor types and quantities across the plant and documented the customer’s OT network infrastructure.
The data collected from the site assessment was then organized and analyzed to serve as a roadmap for facility improvements. E Tech Group formulated a comprehensive, well-structured report for the customer’s management, engineering, and maintenance teams which outlined upgrade recommendations and a clear timeline to implement these upgrades based on the priority level.
Results
E Tech Group worked closely with a plant electrician to complete an on-site assessment of all control panels and OT networks in less than eight weeks. The data from the site assessment was used to provide a comprehensive report outlining automation infrastructure by area, OT network architecture, obsolescence, and recommended paths forward to modernize. The site assessment resulted in a proactive plan to reduce the customer’s likelihood of future controls hardware failures and provided a clear roadmap to strengthen their automation infrastructure.
Challenge
Production health is a synergy between availability, performance, and quality. Overall equipment effectiveness (OEE) is the gold standard to measure these metrics and can help identify early signs of production issues with modern software solutions. This was the challenge for a leading supplier of almond products who needed to find a better way to monitor the real-time efficiency of their lines as well as record production line problems as they occurred. The almond supplier also wanted to own this data and not rely on outside data hosting resources since these often limit extensive data archives. E Tech Group was engaged to upgrade the almond supplier’s performance monitoring system given their experience with the platform, OEE, and database structures.
Solution
The almond supplier requested E Tech Group convert their existing production system to Ignition, an industrial application platform from Inductive Automation, to standardize their SCADA architecture due to its scalability and intuitive design features. The customer requested the project be expedited within a very tight timeline and E Tech Group was ready to put boots on the ground.
E Tech Group provided connection programing to ensure assets were properly tracked in the Allen-Bradley PLCs using Studio 5000 Logix Designer in addition to the Ignition system using the Perspective module. This supported the customer’s ability to have a personalized visualization system that could monitor, control, and record their industrial applications in real-time across any mobile device.
The E Tech Group team set up a database that could effectively log information in an organized manner and enabled seamless data extraction. This structure was difficult to develop from scratch due the high-level of efficiency desired when querying the data. The E Tech Group team engaged their Ignition specialists to configure and connect the SQL database structure with Ignition’s transaction groups and this was later proved to be highly efficient.
Result
The project was completed in three months and the Ignition Perspective module is currently being tested by the customer. The project deployed seamlessly given E Tech Group’s proactive collaboration with the almond supplier. The Ignition platform enabled the customer to track shift start and end times as well as monitor the shift time efficiency. E Tech Group’s Ignition specialists leveraged their in-depth expertise to support the conversion to the Ignition platform, enabling a strong performance monitoring system that could properly track, store, and visualize data to support the customer’s OEE.

Olive oil production relies on robust storage systems. Storage systems that have inadequate controls against light, heat, and oxygen exposure can compromise the freshness of olive oil products and result in considerable production loss for olive oil manufacturers. To combat this, olive oil companies commonly use temperature controlled and light-protected stainless steel tanks to safely store the olive oil until it’s ready to be bottled. Any mismatch in storage capacity to olive oil production presents a manufacturing bottleneck and loss of profits. For one of the largest olive oil producers in California, the ability to scale their business relied on a robust storage system to expand their olive oil processing capabilities. Industry partner Barnum Mechanical Inc. teamed up with E Tech Group to support the company’s storage system needs.
Solution
With the desire to expand their olive oil production, the customer needed a new storage tank farm with greater capacity. The project team assessed existing equipment, current system requirements, and collaborated with various stakeholders to best plan the storage tank system, keeping safety, maintenance processes, and future expansion capabilities top-of-mind. The team interfaced Rockwell Automation ControlLogix PLCs with Wonderware software to support a high-performance control platform with intuitive process visualization. An ifm Actuator Sensor Interface (AS-i) networking solution was designed and integrated in the PLC to simplify wiring efforts with various storage system sensors and save significant time during the installation process, notably as an alternative to conventional point-to-point wiring. Additionally, at the time of this project, it was believed that the team created the largest AS-i network in North America given the extensive networking applications needed for the customer’s large industrial environment.
The team also integrated a Clean-In Place (CIP) system in the controls engineering design to better support production uptime, product quality, employee safety, and cost-effective maintenance. The CIP system provided an automated method to clean interior surfaces of the process equipment without having to disassemble the system for future cleanings. The CIP system was integrated with all storage tanks and transfers to each tank from the olive oil extraction process.
Result
The project and process were a complete success. The customer was able to sufficiently store their increased production of olive oil and then some. The project team was thrilled to have the opportunity to support the new storage tank system and optimize their process environment with a CIP system. With the greater storage capacity, the customer was able expand their product into new geographies and gain greater market share.
Challenge
The era of the PLC5 has come to an end. The controller that once served companies well for many years is now obsolete, resulting in costly aftermarket replacement parts, limited capabilities, and downtime challenges. For one of the world’s largest mozzarella cheese producers, the key challenge with their legacy Allen Bradley PLC5 control system centered around its limited memory capacity and, consequently, the inability to handle new data collection and documentation requirements by U.S. Department of Agriculture (USDA). The cheese producer was further challenged to find a system integrator that had technical expertise with the obsolete architecture to leverage their existing automation investment and determine their migration options. Specialized in this matter, E Tech Group was engaged to plan and manage the migration to the ControlLogix platform.
Solution
The customer’s Allen Bradley PLC5 control system used legacy communication protocols such as Remote I/O and DeviceNet. These networks were converted to ethernet communication with the use of aftermarket gateways and media converters. However, these short-term fixes to remain functional were not well-documented making the decision to reuse existing PLC5 I/O modules with “local” Remote I/O & DeviceNet gateways a difficult issue to troubleshoot while setting up their communication.
The E Tech Group team implemented their success-proven phased approach for a timely migration. The team identified modern Rockwell processors with ample memory to support the new process documentation requirements in addition to the best location to physically install the new PLC in the customer’s existing control panels. Furthermore, E Tech Group assigned a project team of engineers with strong PLC5 conversion experience to properly migrate to the new architecture and leverage the ControlLogix’s functionality.
Results
The preservation of archaic automation systems can be risky and expensive. With consideration to downtime costs and other performance challenges, the investment to migrate to a modern system may pay off sooner rather than later. “The migration provided our customer a solid basis to build for the future.” said Aaron Peri, E Tech Group Project Manager. “It gives them the opportunity to take advantage of newer technologies as they continue to become available and enables them to meet the new, more stringent reporting requirements imposed by the USDA.”
Ultimately, E Tech Group deployed a successful migration strategy that equipped the company to better meet regulatory demands. Although a migration process can seem daunting, it doesn’t have to be with the right system integrator partner.
