keys, then press the DELETE EVENT key. To clear the
entire events log, press the CLEAR EVENTS key.
PMCS Event Log
The PMCS Event Log is a copy of the Event Log tracked
at the PMCS Event Logger software. This option is
available only if the Modbus Monitor is operating as a
slave on a PMCS network and the PMCS Event Logger
client is running. It will appear as an option available
from the Local Events Log displayed at the Monitor.
The PMCS Events Log presented at the Monitor displays
the last 50 events logged by the PMCS Event Logger
software, whether for devices being monitored by the
Modbus Monitor or for other devices being tracked by
the PMCS Event Logger. Alarms are not recorded or
displayed at the Monitor.
NOTE: It is possible that the same event logged by the
Modbus Monitor and the PMCS may have different time
stamps due to differences between the clock settings at
the PC and the Monitor. This may be exacerbated during
Daylight Savings Time, since the Modbus Monitor does
not support automatic Daylight Savings Time correction.
The PMCS Event Log screens may be navigated in the
same manner as the Local Event Log, with the following
exception. The PMCS Event Log may only be viewed;
events may not be deleted, nor may the event log be
cleared, only updated with new events from PMCS.
Press BACK to exit the PMCS Event Log and return to
the Local Events Log.
Using the Modbus Monitor with PMCS
As mentioned earlier, the Monitor’s relationship with
PMCS requires the use of the Modbus Monitor Proxy, a
client software package which requests data from the
DDE Server so that the Monitor can eavesdrop on the
replies from the devices to the server.
Launching the Monitor Proxy application automatically
starts the PMCS DDE Server application if it is not
already running. However, quitting the Proxy does not
affect the PMCS DDE Server. To exit both applications,
quit the Monitor Proxy first, then close the PMCS DDE
Server. If you attempt to exit the Server before quitting
the Proxy, an error message will be displayed warning
you that there are client applications with active DDE
links to the Server.
