Main functionality

The Hitachi Protection and Control IED Manager PCM600 tool provides versatile functionalities for the entire life cycle of Hitachi Energy’s Relion Protection and Control IED applications. This easy-to-handle tool helps you to manage your protection and control equipment all the way from application and communication configuration to disturbance handling. Designed to communicate, PCM600 interacts with IEDs over the fast and reliable TCP/IP via corporate LAN or WAN, or alternatively directly through the communication port at the front of the IED.

PCM600 tool can read and write all configuration and setting data of an IED with a single command. The user interface, workflow, and the IEC 61850-based data model in PCM600 are designed according to the same philosophy as the Hitachi Energy’s Relion Protection and Control IEDs, ensuring smooth and seamless integration between the tool and the IEDs. PCM600 also secures the projects and data created with earlier versions of the PCM600 tool, which enables full backwards compatibility for Hitachi Energy’s Relion Protection and Control IEDs.
