Table 11. IED Addresses for Case Four.
Chapter 3 provides physical wiring requirements and
rules. For commnet wiring, he’ll use Belden M8719 cable.
For RS-485 wiring, he’ll use Belden 3074F cable and the
correct terminating resistors for both ends of the RS-485
networks.
Bill installs the IEDs at the equipment according to the
instructions in each user manual and runs the RS-485
cable for each RS-485 network from the Ethernet Gateway
to each Modbus IED in daisy-chain fashion, one IED to the
next, and terminated at each end.
Bill runs the commnet cable from the Modbus
Concentrator for each commnet segment, grounded only
at the Modbus Concentrator.
He assigns local Modbus addresses to the Modbus IEDs
and sets communication speeds and parameters according
to the instructions in each user manual.
Next, Bill sets the local address at each commnet IED
according to what he wants the Modbus-equivalent address
of each IED to be. He configures the Modbus
Concentrator, either manually or with the autoconfigure
option, following the instructions in the Concentrator
User Manual. During configuration, the Concentrator
probes each of its commnet segments for IEDs, records
their commnet addresses, and assigns a Modbus-equivalent
address so that communication from the PMCS will be
directed to the correct IED.
Bill configures the Ethernet Gateway, assigning a unique
IP network address after he checks with the LAN
administrator to determine which IP addresses are
available. He then sets the serial port communication
parameters for each Gateway port after referring to
document GEH-6505, Ethernet Gateway User’s Guide, for
information on configuring the Gateway serial ports.
Bill assigns a unique IP address to the EPM 7700 meter’s
Xpress Card based on information in the EPM 7700 user
documentation and the addresses he received from the
LAN administrator.
He installs the PMCS software at the host PC and
configures the IED addresses in the DDE server. Next, Bill
modifies the 7700 network configuration file for the EPM
