EPM Device-

Special Considerations

Introduction

The GE EPM 7700, EPM 7600 and EPM 7500 devices add new level of power management capabilities to PMCS. These EPM devices also require some special configuration which is not necessary for other PMCS-compatible devices. This section describes the additional requirements and configuration steps necessary to use the EPM 7700, EPM 7600 and EPM 7500 in conjunction with PMCS.

NOTE: If you are not using the EPM 7700, EPM 7600 or EPM 7500 meters in your

PMCS network, it is not necessary to read this section of the manual.

Although the EPM 7700, EPM 7600 and EPM 7500 meters are compatible with PMCS and its client applications (Waveform Capture, custom wizards, etc.), and EPM 7700, EPM 7600 and EPM 7500 meters may co-exist on the same Ethernet as other PMCS network segments, the EPM 7700, EPM 7600 and EPM 7500 use a slightly different metaphor than a straight PMCS network. An EPM device power- monitoring network is comprised of a number of nodes that are connected to the PMCS workstation through Ethernet links. Nodes in the power-monitoring network are IEDs such as the EPM 7700 meter (power meters are also referred to ‘meters’ or ‘devices’). IEDs may be distributed across one or more networks as required to service the particular application.
