POWER LEADER™ Modbus® Concentrator
Product Overview
GE’s recent introduction of the POWER LEADER Modbus Concentrator brings a new level of performance and compatibility to users of GE’s POWER LEADER communication network (commnet) family of power management devices. Used in conjunction with GE’s Power Management Control System 5.0 (PMCS) software, the Modbus Concentrator allows you to integrate your existing base of commnet devices into the faster Modbus Remote Terminal Unit (RTU) based PMCS network, improving overall system performance while retaining the full functionality of each commnet device.
Modbus RTU is an industry-standard communications protocol that operates on an RS485 network. The Modbus RTU protocol is widely supported for supervisory control and data acquisition (SCADA) systems, building management systems (BMS) and distributed control systems (DCS). Industry leaders such as Multilin, Power Measurements Limited, and GE Fanuc produce Modbus RTU-compatible devices and programmable logic controllers.
Modbus’ open architecture provides a high level of flexibility while reducing the risks associated with proprietary communications protocols. Key benefits of the Modbus RTU protocol include:
∙Devices and systems can be upgraded easily.
∙A wide range of compatible devices from a variety of manufacturers is supported.
∙Communications are extremely flexible, both upstream (to DCS, SCADA and BMS systems) and downstream (to meters and trip units).
GE’s Power Management Control System 5.0 is a powerful yet easy-to-use software package. It provides
communications and control functions for Modbus RTU-compatible devices and (via the Modbus Concentrator) commnet-based devices (such as the POWER LEADER Meter or MicroVersaTrip trip unit). The Concentrator polls data from up to 32 commnet devices and communicates this data with PMCS. PMCS may also communicate with other Modbus-native devices such as the GE Fanuc 90/70 and 90/30 Programmable Logic Controllers, and Electronic Power Meter (EPM) 3710/3720 waveform capture meters.
For current POWER LEADER commnet device users, the POWER LEADER Modbus Concentrator provides a modular and cost-effective way to meet future power management needs by offering a link from commnet to the higher speed Modbus network.
Upgrading an existing commnet network with POWER LEADER Modbus Concentrators and PMCS has two important benefits. First, your network may benefit from increased overall performance, because the Modbus Concentrator provides the higher speed of Modbus communications. Second, PMCS is compatible with many Modbus devices. As your needs change and grow, PMCS supports a wide array of devices to meet those needs, while maintaining compatibility of your commnet devices through the Modbus Concentrator.
Conversely, if you are a user of PMCS equipped with Modbus devices who wishes to use commnet devices, you may add such devices to your network via the Modbus Concentrator. Up to 215 commnet devices may be attached (via multiple Modbus Concentrators) to a single Modbus RTU network, allowing you to build a power management system with maximum functionality and flexibility.
