PDC Control
Range: Enabled, Disabled
Default: Disabled
The synchrophasor standard allows for user-defined controls originating at the PDC, to
be executed on the phasor measurement unit. The control is accomplished via an
extended command frame. The relay decodes the first word of the extended field,
EXTFRAME, to drive 16 dedicated FlexLogic™ operands:
least significant bit) to
PDC NETWORK CNTRL 16
if any, in the EXTFRAME are ignored. The operands are asserted for 5 seconds following
reception of the command frame. If the new command frame arrives within the 5
second period, the FlexLogic™ operands are updated, and the 5 second timer is re-
started.
This setting enables or disables the control. When enabled, all 16 operands are active;
when disabled, all 16 operands remain reset.
TCP Port Number
Range: 1 to 65535 in steps of 1

Default: 4713
This setting selects the UDP port number that will be used for network reporting.
The phasor measurement unit one-shot feature allows pre-scheduling a phasor
measurement unit measurement at a specific point in time. This functionality can be used
to test for accuracy of the phasor measurement unit, and for manual collection of
synchronized measurements through the system.
