Synchrophasors
View Synchrophasors by Using the MET PM Command
The MET PM command shows if there is a serial port configuration error. If any
of the SPCERp bits assert, then the command displays
Y. Otherwise, it displays N.
The MET PM command checks for assertion of the PMTEST bit to show
whether the PMU is in a test mode. If the bit is asserted then the command dis-
plays Y. Otherwise, it displays
N.
The MET PM time command can be used to direct the PMU to display the syn-
chrophasor for an exact specified time, in 24-hour format. For example, entering
the command MET PM 14:14:12 will result in a response similar to Figure 18.6
occurring just after 14:14:12, with the time stamp 14:14:12.000000.
If you are not connected to the PMU when the MET PM time command issues
its timed response, you can use the MET PM HIS command to view this
response. This permits you to issue MET PM time to multiple PMUs at a certain
point in time and then go back later to see the results from all the PMUs at that
point in time.
See MET PM on page 14.39 for complete command options, and error messages.
