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).
Activity logging parameters ACTIVLOG
Activity logging ACTIVLOG
ACTIVLOG contains all settings for activity logging.
There can be 6 external log servers to send syslog events to. Each server can be
configured with IP address; IP port number and protocol format. The format can be
either syslog (RFC 5424) or Common Event Format (CEF) from ArcSight.
