12.11.3 Setting guidelines
The parameters for Single command, 16 inputs (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
Off, Steady, or Pulse.
• Off, 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.
