18.13.6 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).
