Description of Commands
COM RTC
Use the COM RTC to get a report on the status of the configured
synchrophasor client channels.
COM RTC c C and COM RTC c R
The COM RTC C and COM RTC R commands clear/reset the maximum
packet delay. The C and R options are identical.
CONTROL nn
Use the CONTROL nn command to set, clear, or pulse internal Relay Word
bits RB01 through RB32 (Remote Bit 1 through Remote Bit 32). Remote bits
in SEL
OGIC control equations are similar to hardwired control inputs, in that
you use these bits to affect relay operation from outside sources. For control
inputs, external input to the relay comes through the rear panel; in the case of
the CON nn command, external control signals come through the
communications ports. See Control Points on page A.6.11 for information on
remote bits.
If you enter CON nn with no set, clear, or pulse option specified, the relay
responds,
Control RBnn:. You must then provide the control action (set, clear,
or pulse) that you want to perform. (The relay checks only the first character;
you can type Set and Clear.) When you issue a valid CON command, the
relay performs the control action immediately and displays
