Factory-wide visualization streamlines utility management in the “new norm”

The GENESIS64™ visualisation software, a solution for displaying data in process, infrastructure and manufacturing industries, was leveraged to systematically monitor real-time data remotely from equipment, such as operations and loads, helping to address issues raised by the “new norm”.

Key Points

Nagoya Works, one of the main factories in Mitsubishi Electric’s factory automation business, is home to over thirty buildings dedicated to production, administration and services, supporting the many teams of diverse employees who work at this vast facility. Within the premises, significant infrastructure has been built to supply electricity, air, and steam throughout the factory.

For the stable supply of such resources, which are indispensable to production, it is crucial to regularly check the operational status of the utility infrastructure and the load factors of the equipment. The Environment Promotion Section of Nagoya Works’ Manufacturing Systems Division is responsible for taking care of the infrastructure equipment, meaning they not only perform regular maintenance and repairs on equipment, but also monitor the operational status and undertake precautionary measures that will prevent any major problems from occurring. Without such measures any lack of resources may, for example, lead to downtimes in production, or cause overloads that lead to machine breakdowns.

Previously, the members of the environment team had to patrol the buildings and facilities, collecting operational data from individual monitoring systems in power substations and steam boilers. This was quite time consuming since they were all separate systems. Even after they collected the data, they had to add it to a system diagram to analyze the load conditions on the wiring and piping that connects the equipment.

This took more than just man hours. Ryohei Kitada from the Environment Promotion Section explained the issues around this task, “We needed to update the system diagram every time the system configuration changed, and what’s more, we had to be able to understand the status from the data in the diagrams, which depended highly on the skills of each individual. When installing new equipment, we would also have to do a cross-sectional verification to check if the capacity of the current infrastructure would be enough. Therefore, we needed to find a way to bring together the operational data from all the utility equipment in the factory to achieve one-stop access.”

As a solution to these challenges, the team turned to GENESIS64™ smart visualization solution, a SCADA software that makes it possible to integrate and display various sources of data, in this case the utility data at Nagoya Works.

Operational data from equipment throughout the plant is tracked and visualized every 10 seconds
Most of the energy monitoring systems for the buildings were already controlled by programmable logic controllers (PLCs), which were connected to the in-house LAN network. This meant that all the data could be collected by an OPC UA* server, and then visualized by the GENESIS64™ software.
 

The team was easily able to achieve factory-wide integrated monitoring of their energy infrastructure. The energy consumption and equipment status in every building was now displayed on GENESIS64™ and updated in intervals of 10-seconds. Information spanning multiple pieces of equipment could also be reviewed systematically on a single screen. Ryohei Kitada said, “Previously, we would have had to note down the figures from multiple monitoring systems and then enter them on a system diagram manually for further checking. Now, it is possible to get all data instantaneously on a single screen.”

Another benefit from using the smart visualization solution GENESIS64™ was that they were able to check the real-time operational data of infrastructure equipment, making it possible to react quickly in the case of equipment malfunctions. By being able to understand the equipment status without having to patrol throughout the factory, it helped reduce downtime and improve productivity.

At Nagoya Works, they were able to build a factory-wide system without needing to make large investments. This was possible because individual monitoring systems for most equipment already leveraged PLCs, thus the new system required only the addition of Ethernet modules to connect to the in-house network. Also, the factory’s existing Ethernet LAN environment was already available, which meant no additional cost was required in terms of networking.

 

“The only problem was the steam boilers, which didn’t use PLCs but used a monitoring system that was unique to their manufacturer. Therefore, we added a PLC to the existing monitoring system to make it possible to connect it to Ethernet and the OPC UA server, and then display the data in GENESIS64™.” explained Ryohei Kitada. OPC UA is an industry-standard data exchange interface for linking industrial devices to IT resources via networks. The advantage of this system is the degree of freedom it offers – so long as a piece of equipment is OPC UA-compatible it can come from any manufacturer.
 

There were additional benefits from this integrated monitoring system. Since the team was now able to have one-stop access to all the utility data, they were able to simplify the monitoring systems used by each piece of equipment. Ryohei Kitada explained, “In particular, the extra-high voltage electrical substations were previously equipped with multiple monitoring terminals and panels, but thanks to the integrated monitoring achieved with GENESIS64™ we were able to eliminate a number of devices and reduce operational costs by about €6,912.04 annually.”

Agile shift to remote working
It was in 2020 that Nagoya Works started using GENESIS64™ for monitoring the energy infrastructure within its factory. Implementing the project unexpectedly provided an additional benefit. With people being encouraged to work from home due to the COVID-19 pandemic, Ryohei Kitada and his colleagues were able to shift to remote working immediately from the start.

While they were already able to monitor equipment remotely to some extent, even before they started using the SCADA system, it was limited to those systems connected to the network. The others, especially the monitoring systems capable of controlling infrastructure equipment, were not connected to the network due to security concerns. Infrastructure monitoring with GENESIS64™, however, could be achieved by collecting data from PLCs via the LAN network and displaying it in a web browser, which does not provide any access to the control system. “All you need is something like a VPN to connect to the LAN, and then you can safely monitor infrastructure equipment remotely. When we started using GENESIS64™, we didn’t think that remote working would become this important. Consequently, I really feel glad that we went for this system.,” says Ryohei Kitada.

 

Moreover, it was useful not only for working remotely from home, but it also enabled the team to monitor infrastructure equipment at two satellite facilities of Nagoya Works: the Kani Factory in Kani City, Gifu Prefecture, and the Shinshiro Factory in Shinshiro City, Aichi Prefecture.

“If we access a desktop PC remotely, only one person can access the system at a time, but with the web-browser based GENESIS64™ it allows multiple people to view data simultaneously.,” says Ryohei Kitada. “So I am now able to teach or give instructions to the junior staff remotely as we look together at the same data.”

“Abundant examples of GENESIS64™ installations show it is capable of monitoring not only production lines but also utilities and infrastructure equipment in factories.,” says Ikuto Matsuyuki from the Software Section, Sales Department, Nagoya Works, Mitsubishi Electric Corporation. “In this case, we were able to prove the capabilities of GENESIS64™ ourselves by building up a system that made the most of its strengths, such as integrated monitoring and the analysis of data from a variety of systems and equipment, as well as its flexibility in remote access.

Ikuto Matsuyuki continued, “Going forward, we want GENESIS64™ to be able to monitor energy consumption data in even smaller time intervals and expand the scope of the systems and equipment it can monitor, like how much energy is being used for air-conditioning and lighting. Our goal is to make it into an industrial manufacturing solution for those seeking to achieve carbon neutrality.”
