17.9.1 Introduction
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.
17.9.2 Principle of operation
Two multiple transmit function blocks MULTICMDSND:1 and MULTICMDSND:2
and 8 slow multiple transmit function blocks MULTICMDSND:3 to MULTICMDSND:
10 are available in the IED.
Sixteen signals can be connected and they will then be sent to the multiple command
block in the other IED. The connections are set with the LON Network Tool (LNT).
Twelve multiple command function blocks MULTICMDRCV:1 to MULTICMDRCV:
12 with fast execution time and 48 multiple command function blocks MULTICMDRCV:
13 to MULTICMDRCV:60 with slower execution time are available in the IED.
Multiple command function block MULTICMDRCV has 16 outputs combined in one
block, which can be controlled from other IEDs.
The output signals, here OUTPUT1 to OUTPUT16, are then available for
configuration to built-in functions or via the configuration logic circuits to the binary
outputs of the IED.
MULTICMDRCV also has a supervision function, which sets the output VALID to 0
if the block does not receive data within set maximum time.
