EPM 7700
The EPM 7700 Device Configuration dialog box is slightly different from the other
PMCS device types, containing two extra fields and requiring minor differences in
configuration. The Device Configuration dialog for the EPM 7700 is shown below,
followed by the special configuration requirements.
The Node Name field requires that you enter the name of the computer running the
Communications Server that connects to this particular device. Depending on the
configuration of the EPM 7700 network, this can be either the Primary node
computer, or a computer setup as a “Full Station” Secondary node. Refer to DEH-
40035, the GE 7700 Gateway Users Guide, and GEH-6514, PMCS Read This Book
First, for more information on network configuration. The Node Name field is
required because the EPM 7700 does not use the same DDE server as the rest of the
standard PMCS devices, and the wizard must be directed to the location of the
correct Communications Server for proper configuration of DDE topic names.
Also, the Application Name field must be completed as ION_LINK rather than
GE32MODB or GE32ENET for the EPM 7700 device. The ION LINK program is
installed during initial PMCS setup if the EPM 7700 software option is selected.
When configuring Wizards on Secondary nodes, the Application Name field entry
does not follow the PMCS wizard convention of “\\RemoteComputer\ION_LINK”.
EPM 7700 Secondary nodes run a local copy of the ION LINK server, thus the
application name for EPM 7700 Tabular Data Wizards is always “ION_LINK”
whether the wizard is installed on the Primary node or a Secondary node. The Node
Name entry determines if the wizard is on a Secondary node.
The Gateway Name field must be completed with GE77GTWY, the application
name of the GE 7700 Gateway Server program. When configuring the EPM 7700
Tabular wizard on a Secondary node, the Gateway Name does follow the PMCS
wizard convention of “\\RemoteComputer\GE77GTWY” in the Gateway Name field,
where ‘RemoteComputer’ is the name of the PC where the GE 7700 Gateway
application is running – the Primary Node. The following example shows a Device
Configuration Dialog box as it would appear when configuring a Tabular Data
wizard on a Secondary node. The Node Name field contains the name of the Primary
Node computer, the Application Name field is ION_LINK (as it is for ALL EPM
7700 wizards on ANY node) and the Gateway Name field points to the GE 7700
Gateway Server running on the Primary Node PC.
