CLIOL(R)824A Relay Output Module
One instance of the LONMARK open-loop sensor object has
been assigned per input of the CLIOL824A/CLIOLR824A
Relay Output Module.
Each output object has its own configuration properties,
except for heartbeat configuration, which will be shared
among all objects.

Default Value
Value = 0
State = -1
Start-up Behavior
At start-up, i.e., power-up or reset, all nvi's will be initialized
with INVALID, leading the actuator to drive to the configured
safety position after 1 minute.
Receive Heartbeat
The default configuration for “Receive Heartbeat” is 300 sec.
If no nvi update is received during this time, the field devices
will go to their configured safety positions.
