Plant Digitization Through Real Time Locating System

Plant Digitization Through Real Time Locating System

I first met Quuppa and saw a demo of its real time locating system at the 2018 Hannover Messe. I have written about it here and here. The company has developed an interesting technology and application.

They wrote about industrial  applications picking up, so I asked for an example. Below is a story about defining a problem, sourcing a solution, and then implementing it.

NGK Ceramics is a global specialist in the manufacturing of ceramic substrates used in catalytic converter applications for automotive, truck and off-road vehicles. The US manufacturing facility, located in Mooresville, North Carolina, covers more than 500k square feet with 365 days a year, twenty-four hours a day operations.

The facility was initially designed in 1988 to serve a limited geographical area in the US. However, with the business growing faster than expected and more areas being served by the same production plant, NGK faced a major challenge: how to grow the capacity of the North Carolina industrial plant. Efficiency was clearly the answer. As a first step, ASRS (Automated Storage and Retrieval Systems), together with AGV’s (Automated Guided Vehicles), were introduced to move pallets and materials in the shop floor without human intervention.

Even if this mitigated the problem, it was still not enough to manage high, yet variable, production demands in the long run. As a result, during production peaks, the pallets transporting both raw materials and semi-finished goods were temporarily stored all around the shop floor according to specific procedures. While this addressed the problem of lack of (ASRS) storage space, it introduced a significant new one, the additional time spent finding and moving pallets from one production phase to the next. At least two workers per shift were assigned to this task: just searching for and moving pallets.

In addition to this, at least once a year a complete plant inventory is required to verify all materials stored in the facility, but not yet shipped or sold. During this activity, the entire plant was surveyed, and all pallets were identified and verified against the data registered in the internal ERP system. This activity could take up to one week, with the slow down (if not interruption) of the production activities. Inevitably, any items lost or duplicated created an impact on the bottom line.

To deal with these issues, in 2017 NGK Ceramics decided to explore how solutions based on a Real Time Locating System (RTLS) could help by providing a Digital Twin of the manufacturing plant: the location of every pallet would be tracked continuously and that data would be synchronized with NGK’s MRP systems. This tracking of pallets provides a real-time view of where they are located in the industrial plant, with a number of supporting services to easily and rapidly search them and manage the production cycle.

TRACKING SOLUTION: REQUIREMENTS NGK Ceramics decided to evaluate a number of different scenarios for implementing a RTLS to track the progress of material and semi-finished goods throughout the flow of its manufacturing process. The key requirements to be addressed by the solution were:

• Configurable tracking accuracy: since the industrial plant covers a large area, with different uses of the spaces within the plant (production area vs. stocking areas vs. corridors), the ability to vary the location accuracy of asset tracking was important. In some areas, where the density of pallets is typically high (such as the warehouse) sub-meter accuracy is required in order to easily locate a specific pallet among the many stocked there. On the other hand, a 10 metre accuracy is sufficient in corridors or transit zones, where it is sufficient to track the presence of the pallet in the zone;
• Infrastructure cost: as NGK Ceramics facility is rather large, the number of RTLS antennas required to achieve the desired accuracy was clearly an important variable of the solution to be adopted. This impacted both the cost of the infrastructure as well as the costs related to the cabling (e.g., connectivity and power). Another factor was the cost of the tags to be attached to the pallets. This extended beyond the capital cost to also include the cost of replacing the batteries in the tags.
• Asset search and location functionality : NGK wanted this Digital Twin to be used in a variety of ways, from centralized systems to hand-held devices using a Google maps style red dot metaphor, so how the system was able to process the information and extract actionable knowledge for the final user (the worker in the shop floor) was important. This required addressing issues related to the usability and ergonomics of the system, Machine-2-Machine (M2M) application integration, while delivering on its intended use and the need to facilitate the searching and location of assets.
• Maturity of the solution: an enterprise-ready solution was requested. This refers to the support for active monitoring services of both the platform and the RTLS infrastructure. Any device or software component deployed in the facility needed to be monitored, with notifications sent in case of anomalies in the system. This includes the battery status of the devices/tags used for tracking the pallets.

DIGITISING THE PRODUCTION PROCESS NGK retained the services of Statler Consulting a specialist in the area of beacons and RTLS technologies, and issued a Request for Proposal (RFP) for a solution able to track in real-time the assets in their facility, and to deliver the necessary supporting services for the optimisation and real-time control of their production process. Among the many solutions proposed, ThinkIN was chosen as it proved to be the best match to the requirements identified by NGK. ThinkIN is an innovative IoT platform for real-time tracking, monitoring and control of assets and workforce in industrial environments.

ThinkIN technology is based on Quuppa4 RTLS for the high precision location of assets in the shop floor. Quuppa utilizes a unique combination of Bluetooth Low Energy (BLE) and the Angle of Arrival (AoA) methodology, as well as advanced location algorithms that have been developed over the course of more than 15 years, to calculate highly accurate, real-time indoor positioning, even in the most demanding environments, including inside warehouses and manufacturing facilities. The low-power system is a reliable, highly-customizable, scalable and costefficient solution for providing an accurate “dot on the map.”

ThinkIN platform provides a comprehensive set of services ranging from real-time support (e.g, asset search and location, alerts and geo-fencing, etc.), to Industrial IoT analytics. It also includes a number of tools to support the active monitoring of the infrastructure (both hardware and software) and a comprehensive set of user interfaces to explore the data collected and used to locate assets in real-time in the shop floor. In terms of tracking technology, Quuppa RTLS provided an optimal trade-off in terms of location accuracy, number of antennas required to cover the NGK facility and maturity of technology.

Overall 95 antennas are used to cover the complete NGK facility, with a location accuracy of approximately one meter in the areas of interest and approximately 5 meters in other areas. Different tag form factors were evaluated. Eventually, a custom Bluetooth Low Energy tag with a slim badge form factor was designed and manufactured in order to optimally align with NGK’s existing manufacturing process. The tag ensures 4+ years of life without battery replacement. Pallets, carrying products or semi-finished goods, are identified by means of their Product Travel Ticket (PTT), which includes all the necessary information about the kind of product manufactured, together with information on production stage ( e.g. forming line, firing in kilns, etc.). At the very beginning of the production process, an RTLS TAG is associated with the pallet Travel Ticket through a mobile application running on a scanner.

The application allows the scanning of both the QR code present on the PTT and the QR code on the TAG. This association creates a Digital Twin of the pallet, which is now tracked in real-time throughout its manufacturing process. The pallets can now be easily located through the ThinkIN mobile service. Additionally, plant-level views allow staff to monitor the status of the pallets across the entire facility, maintaining an always up-to-date inventory of all pallets stocked or moving in the facility.

Starting from ThinkIN open APIs, a dedicated mobile interface was created for an optimal utilisation of data over the shop-floor and to facilitate the work of employees in the search and location of pallets with a specific Travel Ticket. Figure 3: Tracking of assets in NGK facility Additional services delivered through the ThinkIN platform enable the quality control of pallets depending on their production stage, with alerts being triggered if the pallet moves into areas not allowed. To prevent this, a specific geo-localised workflow is imposed on the travel path of pallets depending on their production process. Warnings are raised when the specific workflow is not adhered to.

LOOKING AHEAD

The project started in 2017 with an initial pilot phase, and is now scaling up to the entire production plant with a possible extension in the coming years to other NGK manufacturing sites. NGK is planning to obtain a return on their investment in a 2 year time frame. Today we are in year two and ThinkIN solution is integrated with the production control system adding value to the manufacturing process by making the pallet searching process more effective.

ThinkIN’s platform has allowed NGK to digitize the shop floor by recreating the plant on screens accessible to all workers. Thanks to the data collected by tags and devices, workers can use the interface to find pallets around the manufacturing plant based on the information of the goods transported by the pallets, such as product type, bench number, kill cycle, and other key criteria for the production routing.

The efficiency of the shop floor was significantly increased thanks to ThinkIN for Industry. In the first year, NGK Ceramics reduced the costs of the wasted time searching for pallets and of the time spent doing the annual inventory. Thanks to the new solution, the inventory is constantly up-to-date. Moreover, the accuracy in tracking reduced the risk of accidents caused by the movement of pallets with forklifts in the shop floor searching for the needed pallet. ThinkIN for Industry, therefore, is a location intelligence technology that by capturing data from the shop floor in a digital platform offers the chance to automate the real world in new ways that can enhance and optimise workflows in the shop floor.

MES Application Conforms to Your Processes

Manufacturing is tough, says FactoryFour, a startup in the MES space. Managing it shouldn’t be, it follows up.

Param Shah, co-founder and CEO of FactoryFour, told me that he and his partner researched build-to-order and configure-to-order manufacturing in the orthopedic device market they discovered that manufacturing planning was done by a combination of paper and spreadsheets.

Further research showed that typical MES platforms required the manufacturer to configure its processes to conform to the workflows and parameters of the software. People really didn’t want to do that. They would simply ignore the cumbersome software and opt for something familiar and flexible.

FactoryFour’s simple value statement goes like this:

Today’s manufacturing software is manual and complicated. Manually managing the 100 little tasks that go into pushing products out the door causes unnecessary production errors and delays.

Managing it shouldn’t be complicated. Simple and automated. The freedom to focus on improving processes, eliminating bottlenecks, and growing revenue. Everything else is automated.

The manufacturing Shah studied was highly manual. In the orthopedic space where custom pieces are manufactured, order process errors are common. Employees find it hard to keep track of where products are in the manufacturing system.

FactoryFour uses native cloud technology. It customizes order intake, using it to inform the manufacturing system. In that system, engineers configure workflows, draw it up then put in software. Therefore the software conforms to the manufacturer’s workflow. The use barcode, RFID, etc., to track the process. FactoryFour connects to other software systems as required.

The Workflows allow rules and an “if this then that” process. It can, for example, integrate with shipping apps and APIs. If shipping stage goes active, it will call up software and generate shipping documents, find UPS tracking number, send to customer automatically. If error is called, it will notify and assign tasks.

Its API connects data to SAP, Epicor, Oracle, and the like. It tracks human labor through scans.

The company’s focus is on custom manufacturing and configure to order with high traceability needs. Channel includes consultants, SIs, and hardware companies.

I asked about usability. “Our first hire was UI UX person,” Shah told me. “We are extremely visual, using colors and designs effectively. Screens are intuitive, geared to technicians with only one or two buttons on a screen not 60.“

This is a young company that just completed its A round of financing looking to shake up the MES market.

Schneider Electric Foxboro Products Offer Enhanced Visibility Into Plant Profitability

Using technology to help plant managers and plant teams make their plants more profitable. In fact, they can even track and prove their profitability enhancements.

The Foxboro User Group met this week in Foxborough, MA at the company headquarters. Aside from the opportunity to meet with a number of company executives for in-depth discussions, there were two significant news releases. And, by the way, Foxboro claims a 100% return on investment with its new DCS in less than a year.

Why it’s important: This signals the culmination of a lot of strategic thinking at Foxboro about helping operators and others in a plant make decisions based on profitability as well as operating parameters.

First the new DCS.

Schneider Electric has improved the capabilities of its EcoStruxure Foxboro DCS, the company’s flagship distributed control system. EcoStruxure is Schneider Electric’s IoT-enabled, open and interoperable system architecture and platform.

With patented, customizable real-time accounting (RTA) models built in, the EcoStruxure Foxboro DCS not only allows the industrial workforce to evaluate the real-time financial performance of an industrial operation directly at the equipment asset level, it also empowers them to more easily identify the impact their actions and decisions have on the profitability of the operations they control. The RTA models can be manipulated and adapted to suit a variety of industrial operations across multiple segments, enabling a wide range of customers to reap far more value from their existing systems.

“For the most part, by the time business managers receive their monthly updates from whatever enterprise resource planning systems they use, the information is no longer relevant to the operational business decisions they need to make, or should have made,” said Peter Martin, vice president, Innovation and Marketing, Process Automation, Schneider Electric. “The EcoStruxure Foxboro DCS breaks the mold because our RTA models help control value asset to asset, all the way up the enterprise. By aligning process control with the hierarchy of the plant, we can provide far more visibility into the financial performance of every plant asset and asset set. That allows plant personnel to understand the impact their decisions have on the business and business leaders to understand the impact their decisions have on the operation, in real time.”

Along with the RTA models, the continuously current EcoStruxure Foxboro DCS features high-capacity, high-availability control processors; more powerful, fit-for-purpose I/O; intuitive, role-based engineering tools; and enterprise-wide analytical tools and capabilities. Additionally, its hardened cybersecure design and secure integration with the company’s market-leading Triconex safety systems protect the facility’s critical assets and allow for continuous production. Moreover, its automated, enterprise-wide, real-time condition monitoring and predictive maintenance capabilities minimize unplanned shutdowns, maximize uptime and lower maintenance costs by 30 percent or more.

EcoStruxure Foxboro DCS works in tandem with EcoStruxure Profit Advisor, Schneider Electric’s new software solution that applies the company’s RTA models to help the industrial workforce diagnose and analyze the profitability of processes throughout the plant. Whereas EcoStruxure Profit Advisor connects to any process historian to mine both historical and real-time data, the EcoStruxure Foxboro DCS takes the next step by building the algorithms into the process controllers themselves, thereby extending real-time accounting capabilities to every point in the process.

Maintenance Advisor

Of great interest to maintenance and reliability organizations, but also plant managers, is the improved Maintenance Advisor and Condition Advisor. Working in tandem, these bring information from the field relative to the condition of assets. This information can be used for information or integrated into workflow for actions.

The company’s new EcoStruxure Maintenance Advisor software, with embedded EcoStruxure Condition Advisor, bridges the gap between operations and maintenance, providing predictive maintenance and decision support for plant-wide assets.

Delivered in a single unified dashboard, EcoStruxure Maintenance Advisor monitors the real-time health of plant-wide assets to detect abnormal operating conditions. It then automatically provides actionable, easy-to-understand alerts with the proper context, along with potential reasons for the abnormal condition and possible actions to rectify it.
New EcoStruxure Condition Advisor for OPC DA enables real-time, automated condition monitoring of any OPC DA-compliant asset, such as intelligent electronic devices, motor starters and drives. This new capability complements existing Condition Advisors, which monitor the condition of Fieldbus Foundation, HART and Profibus process instruments.

The major manufacturing management software trend of the year is modular. Let’s make it easier to buy, install, configure, and use.  The latest company with a major upgrade is Parsec. The company has announced launch of the latest version of its modular manufacturing management software: TrakSYS. A unified, 100% web-based platform with multiple, fully-integrated modules, TrakSYS can be used as a full manufacturing execution system (MES), or deployed to solve one or more business challenges — from performance and quality to e-records, maintenance, workflow, and more.

TrakSYS gathers critical operations data from machines and people, and delivers insights to help operations run more productively, safely and profitably. Leveraging 30 years of experience in delivering manufacturing solutions, Parsec designed this version of TrakSYS to simplify manufacturing operations in a variety of industries –  from pharmaceutical and packaged goods to food and beverage, automotive and more.

“Manufacturing is complex, but your software shouldn’t be,” said Eddy Azad, CEO for Parsec.  “The key advantage of TrakSYS lies in its flexibility. TrakSYS has all of the power of traditional MES, without the ‘weight’ and cost. Manufacturers can simply turn on the features they want at any time and customize a solution that specifically addresses their needs.”

Manufacturing Management – Simplified

Under the strain of increased regulations for accurate, accessible electronic recordkeeping, manufacturers need a real-time view of manufacturing operations. The pressure to increase quality and quantity, while reducing costs, also has manufacturers seeking a deeper understanding of trends and patterns and new ways to drive efficiency. Custom software and traditional MES solutions can be used to address these concerns, but they are costly and complicated to manage.

Azad, explains, “It’s all about making software easier to use and more cost-effective to deploy, maintain and scale.”

One Platform, Many Applications

TrakSYS is an integrated platform that contains all of the functionality in one package. The modular nature of TrakSYS brings complete flexibility to deploy only the functions that are required, without a major software upgrade. TrakSYS business solutions include OEE, SPC, e-records, maintenance, traceability, workflow, batch processing, sustainability, labor and more.

“Whether a factory has one line or 100, uses manual or automated production processes, relies on PLCs or an IIoT infrastructure, TrakSYS can help. We designed this powerful version of our proven software with the idea that software should help manufacturers to do their job, not become the job,” added Azad.

The latest version of TrakSYS is now available.

Manufacturing Software Beyond HMI/SCADA

A manufacturing software supplier must go beyond where they are to keep pace with today’s needs. GE Digital just announced such an extension–to offer decision support capabilities. The new GE HMI/SCADA software offers “comprehensive and best-in-class monitoring and visualization capabilities,” as well as work process management, analytics, and mobility. Based on ISA high performance design principles, this solution enables companies to troubleshoot faster, reduce waste and increase productivity.

“Most SCADA systems are still configured as HMIs – simply a display to indicate status,” said Matthew Wells, General Manager Automation Software for GE Digital. “In developing this new generation solution, we have combined industry standards, GE research and Industrial Internet technologies to exceed traditional HMI/SCADA, increasing operational efficiency and delivering on business outcomes.”

Context-driven navigation and situational awareness

The new GE software features a context-rich HMI that changes as the user moves through the system. Navigation is derived from a structured asset model. Using the model, the software always can provide operators with the most relevant information – in context – and minimize time to response. Additionally, the structured asset model mapped to the SCADA database significantly speeds configuration. Modern technologies such as HTML5 and Web HMI allow for centralized development and deployment, as well as accessibility anywhere in multiple form factors.

“With high performance HMI/SCADA, operators are able to quickly determine an abnormal situation and get to the root causes of many issues,” said Sergio Chavez, Automation Engineer with Los Angeles Dept. of Water and Power. “We help operators visualize a process and make alarms very visible. We’re shaving the time it takes for operators to act on a situation.”

To help engineers create the right user experience, GE also provides predefined smart objects and templates designed using efficient HMI concepts. Standard layouts and cards – such as trends, alarms, alarm summaries, and KPIs – are available out of the box, speeding configuration and improving user situational awareness.

Task management and mobility

Additionally, GE’s fourth generation HMI/SCADA portfolio has task management capabilities, triggering the right actions, at the right time, by the right person, in the right place based on alarms or other events. GE’s new Workflow 2.5 and Mobile 2.0 solutions extend the capabilities of Decision Support HMI/SCADA further, helping companies achieve their critical business outcomes with integrated workflows and intelligent alarming, available anytime and anywhere.

“Operator effectiveness allows operators the opportunity to grow professionally,” according to Bill Fritz, Director of Public Works, Waterford Township, Michigan. “They can reinvent themselves and gain new value-added skills. They can take on new roles.”

GE’s Wells explained, “Use technology to improve the operator experience and manage operations for greater efficiency. With just a quick look, operators today should be able to recognize which information requires their attention and what it indicates – which speeds response and drives to business outcomes.”
