Energy Control Pack provides visualisation to optimise energy usageThe ME96NSR panel meter from Mitsubishi is an innovative solution to monitor and record energy consumption that has been developed to provide seamless integration with Mitsubishi Electric system Q controllers via a CC-Link network, with the information then transferred to a higher level SAP system. Here the data can be recorded and readily analysed.
The energy monitoring solution was developed as part of the Future Factory Initiative. Managed by the SAP Research Centre in Dresden, Germany, the Future Factory Initiative is a joint effort between SAP Research and industrial and academic partner organisations to foster research and development for the manufacturing industry.
Mitsubishi Electric is a core partner for the Future Factory Initiative, collaborating with SAP Research on a number of research projects for the manufacturing industry. The smart energy meter and seamless SAP integration is one of the first practical results of this collaboration, offering industry and simple and effective, tightly integrated means of measuring, recording and analyzing energy usage data.
The ME96NSR is a small and flexible DIN sized electronic measuring instrument that measures load status and displays various values taken from the high voltage/low voltage circuits of power distribution systems. An integrated CC-Link interface allows the panel meter to be easily networked to Mitsubishi Electric System Q controllers.
Now Mitsubishi Electric has introduced the Energy Control Pack (ECP). Built on Mitsubishi's e-F@ctory concept, the ECP provides the necessary visualisation and control to optimise energy usage, limit power consumption over time and manage power peaks, streamlining processes to deliver significant energy savings.
Developed with e-F@ctory Alliance Partners INEA and LEM, ECP fully integrates energy management with other enterprise systems. It collects live data from all points of energy consumption for analysis by multiple levels of management systems. On the plant floor this provides the means, for example, for motor or line speeds to be automatically trimmed, loads to be more closely matched and temperatures to be controlled in real time, delivering considerable energy savings. At the same time, product quality, production reliability and overall productivity are enhanced.
The ECP is based on a series of proven control modules which can be selected, configured and scaled to suit any application. It bundles together hardware, software and documentation for "out-of-the-box" energy management. The pack is built around Mitsubishi Electric FX3U or Q series PLCs programmed with a dedicated Energy Control algorithm. Various loads can be connected and measured by energy meters that interface to the PLC with pre-made function blocks delivering seamless communications. A user-friendly Mitsubishi GOT series HMI is connected to the PLC and used for setting up the application and subsequently to monitor the system. Optionally, a SCADA web application, on a separate server, can provide enhanced usability.
At its simplest level, the ECP Compact configuration provides a single PLC which is capable of controlling up to 16 electrical loads. Integral software automatically collects and analyses all necessary data. The ECP Modular configuration is for complex systems with more than 16 loads which are dispersed to several locations; several PLCs are installed, with one defined as the master and the rest as slaves. Finally, there is the ECP Open for the most complex systems that require a project-based approach, integrating with wider energy systems such as air, gas, oil, water, space heating or air conditioning.
The Energy Control Pack provides easy connection to IT databases and other information systems, and is completely scalable to suit applications of different sizes and functionalities. It provides a parameter-based set-up that eliminates the need for complex programming. Parameters such as load type, tariff schedule and others are simply set via the HMI. Once operating, the terminal displays current data as it is collected.
