3.12.10.2 Setting guidelines
The parameters for Single command, 16 signals (SINGLECMD) are set via the local
HMI or PCM600.
Parameters to be set are MODE, common for the whole block, and CMDOUTy which
includes the user defined name for each output signal. The MODE input sets the
outputs to be one of the types Disabled, Steady, or Pulse.
• Disabled, sets all outputs to 0, independent of the values sent from the station
level, that is, the operator station or remote-control gateway.
• Steady, sets the outputs to a steady signal 0 or 1, depending on the values sent
from the station level.
• Pulse, gives a pulse with 100 ms duration, if a value sent from the station level is
changed from 0 to 1. That means the configured logic connected to the command
function block may not have a cycle time longer than the cycle time for the
command function block.

Scheme communication logic for
residual overcurrent protection
ECPSCH - 85
3.13.1.1 Application
To achieve fast fault clearance of ground faults on the part of the line not covered by
the instantaneous step of the residual overcurrent protection, the directional residual
overcurrent protection can be supported with a logic that uses communication channels.
