2.2.5 Transmission
Data
The following data are transmitted every 60 electrical degrees for pilot wire communication or
every 30 electrical degrees for direct fibre optic communication to the remote terminal:
A-phase current
B-phase current
C-phase current
Sampling synchronization control signal
Synchronized test trigger signal
User-programmable commands
Sampled current data, for the current and previous samples, are transmitted to the remote terminal
in pairs.
In addition to the above data, cyclic redundancy check bits are transmitted to monitor the
communication channel. If a communication failure is detected at the local terminal, the output of
differential protection is blocked.
A synchronized test trigger signal is used to test the differential protection simultaneously at all
terminals. For details, see Section 4.2.7.4.
User programmable commands
Any signals (On/off data) shown in Appendix B can be assigned to COM1 to COM5, SUB_COM1
to SUB_COM5 and SUB2_COM1 to SUB2_COM12 as user programmable commands by using
the PLC function. The default setting is as follows:
