Configuring the EPM Device Network

Configuring the EPM Device Network

The PMCS installation routine described earlier in this manual creates initial workstation and software node entries in the EPM 7700 network configuration file. After EPM 7700 software components are installed, the next step is to add Ethernet sites and devices to the PMCS power-monitoring network using Network Builder software.

Running Network Builder

Network Builder software presents your EPM power-monitoring network graphically, showing the installed components in a hierarchical tree. Network Builder allows you to edit the Network Configuration file— the file that identifies every node in the EPM power-monitoring network.

The first step is to run Network Builder from the Start Menu: (Programs > Power Measurement Ltd > Utilities > Network Builder.)

The following figure shows how Network Builder displays a system comprised of the basic EPM software components, a single EPM 7700 meter, a Primary Node and a Stationless Secondary node (also called a ‘view node’).

Workstation: the network name of the

Primary Node computer running the

Communications Server and GE 7700.

Software nodes: Stationless Secondary nodes appear here.

Ethernet Site: Defines the Ethernet connection between the PMCS system and the connected device(s).

Device: Name(s) of attached device(s).
