Operation principle

There are 10 instances of the MULTICMDSND function block. The first two are fast (8 ms cycle
time) while the others are slow (100 ms cycle time). Each instance has 16 binary inputs, to
which 16 independent signals can be connected. Connected signals are sent through
MULTICMDSND to the receiving equivalent, MULTICMDRCV, located on a different IED.
The MULTICMDRCV function block has 16 binary outputs, all controlled through the command
block of one or many MULTICMDSND function blocks. There are 60 instances of the
MULTICMDRCV where the first 12 are fast (8 ms), and the others are slow (100 ms).
Additionally, the MULTICMDRCV has a supervision function, which sets the output connector
"VALID" to 0 (zero) if its block does not receive any data within the time defined by
tMaxCycleTime.
LON connections are established using LON network tool (LNT).
