6.1.1 OVERVIEW
Although setpoints can be entered manually using the front panel keys, it is much easier to use a computer to
download values through the communications port. A free program called PQMPC is available from GE Power
Management to make this as convenient as possible. With PQMPC running on your personal computer under
Windows it is possible to:
•
Program/modify setpoints
•
Load/save setpoint files from/to disk
•
Read actual values
•
Monitor status
•
Perform waveform capture
•
Perform harmonic analysis
•
log data
•
triggered trace memory
•
Get help on any topic
•
Print the instruction manual from compact disc
PQMPC allows immediate access to all the features of the PQM with easy to use pull down menus in the famil-
iar Windows environment. PQMPC can also run without a PQM connected. This allows you to edit and save
setpoints to a file for later use. If a PQM is connected to a serial port on a computer and communication is
enabled, the PQM can be programmed from the Setpoint screens. In addition, measured values, status and
alarm messages can be displayed with the Actual screens.
6.1.2 HARDWARE CONFIGURATION
The PQM communication can be set up two ways. The figure below shows the connection using the RS232
front port. Figure 6–2: PQMPC COMMUNICATIONS USING REAR RS485 PORT shows the connection
through the RS485 port. If the RS232 option is installed, this port will be visible on the front panel.
