5.4 SYSTEM SETUP
•
NETWORK REPORTING IDCODE: This setting specifies an IDCODE for the entire port. Individual PMU streams
transmitted over this port are identified via their own IDCODES as per the device settings. This IDCODE is to be used
by the command frame to start or stop transmission, and request configuration or header frames.
•
NETWORK REPORTING RATE: This setting specifies the reporting rate for the network (Ethernet) port. This value
applies to all PMU streams of the device that are assigned to transmit over this port.
•
NETWORK REPORTING STYLE: This setting selects between reporting synchrophasors in rectangular (real and
imaginary) or in polar (magnitude and angle) coordinates. This setting complies with bit-0 of the format field of the
C37.118 configuration frame.
•
NETWORK REPORTING FORMAT: This setting selects between reporting synchrophasors as 16-bit integer or 32-bit
IEEE floating point numbers. This setting complies with bit 1 of the format field of the C37.118 configuration frame.
Note that this setting applies to synchrophasors only – the user-selectable FlexAnalog channels are always transmit-
ted as 32-bit floating point numbers.
•
NETWORK PDC CONTROL: The synchrophasor standard allows for user-defined controls originating at the PDC, to
be executed on the PMU. 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
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.
•
NETWORK TCP PORT: This setting selects the TCP port number that will be used for network reporting.
•
NETWORK UDP PORT 1: This setting selects the first UDP port that will be used for network reporting.
5
•
NETWORK UDP PORT 2: This setting selects the second UDP port that will be used for network reporting.
