Application

The IED can be provided with a function to send and receive signals to and from other
IEDs via the interbay bus. The send and receive function blocks has 16 outputs/inputs
that can be used, together with the configuration logic circuits, for control purposes
within the IED or via binary outputs. When it is used to communicate with other IEDs,
these IEDs have a corresponding Multiple transmit function block with 16 outputs to
send the information received by the command block.
Setting guidelines
Settings
The parameters for the multiple command function are set via PCM600.
The Mode setting sets the outputs to either a Steady or Pulsed mode.
