4.1 L_IOParComGuarding − Monitoring function
This function block parameterises, via the input setting, the monitoring functions provided by the I/O
system.
Included are
·
NodeGuarding, Heartbeat and a Lenze−specific monitoring function,
·
setting the output channels’ switching behaviour in the case of an error via input
byErrorBehavior.
The function block output indicates the transmission status.

ð Inputs (Variable type: VAR_INPUT)
Variable name Data type Information/possible settings
bExecute Bool Execute write request
FALSE ä TRUE Write request is executed
byNodeAdr Byte Device address: 1 − 63
tGuardTime Time Nodeguarding: Time interval.
An NMT master must poll the I/O system within the guard time period.
Default t = 0 ms
t = 0 − 65535 ms
byLifeTimeFactor Byte Lifeguarding:
Life Time Factor x Guard Time = Life Time.
Once this period has expired, the I/O system is switched into a predefined status.
tHeartbeatConsumerTime Time Heartbeat: Monitoring interval.
The I/O system is switched into a predefined status if no telegram is received from
the Heartbeat Producer within this interval.
t = 0 − 65535 ms
byHeartbeatConsumerAdr Byte Node ID of the device to be monitored. (HeartbeatProducer Node ID)
