4–6 Trouble-Shooting Guide
Symptom Possible Cause Corrective Action
1.
No communication to
any IEDs on the
network. 1. Host PC not powered. Check that the host PC has control power and is
running correctly (no PC error conditions exist).
2. Windows 2000 SP2 not
running correctly.
Check that Windows 2000 SP2 is properly installed and
running correctly (no crashes or system lock ups).
3. PMCS not properly
installed or not properly
configured with IED
addresses and
communication settings.
Check that PMCS is correctly installed and running
and has been configured with the Modbus addresses
and communication settings of all attached IEDs.
4. DDE Server not running. Check that the DDE Server is correctly installed and
running.
(RS-485 host only) 5. RS-485 interface installed
incorrectly or not
functioning.
Ensure that the RS-485 card or RS-232/RS-485
converter is properly installed at the host PC and that
the RS-485 cables are correctly attached to the interface
card or converter.
RS-232/RS-485 converter: Ensure that the DIP switches
inside the converter are set properly for the baud rate
of the RS-485 segment. See the converter
documentation for further information & instructions.
(Ethernet host only) 6. Ethernet network down
or improperly connected.
Check the connections at the host PC Ethernet card for
loose or improper connections. Check with LAN
personnel for network-wide problems that might be
affecting the Ethernet Gateway or host.
(Ethernet host only) 7. Ethernet Gateway not
powered, not connected
to Ethernet or RS-485
ports, or connected but
improperly configured.
Check that the Ethernet Gateway has control power
and is properly connected to the Ethernet and to the
RS-485 ports. Make sure that the Gateway has been
properly configured for the attached RS-485 networks.
(EPM 7700 only) 8. Device communication
settings are incorrect.
Refer to the XPRESS Card manual that accompanied
your meter. PMCS Ethernet connections require the
following XPRESS Card settings:
1. An IP address (mandatory)
2. A subnet mask (network-dependent option)
3. A default gateway (optional; required to
communicate between networks)
4. IP port number must be set to 7700 (mandatory)
5. Use the ION protocol (mandatory)
