9. If the Connection Reaction time limit is acceptable, click OK; or for more
complex requirements, click Advanced to set the Advanced Connection
Reaction Time Limit parameters.
The Timeout Multiplier determines the number of RPIs to wait for a
packet before declaring a connection timeout.
The Network Delay Multiplier defines the message transport time that is
enforced by the CIP Safety protocol. The Network Delay Multiplier
specifies the round-trip delay from the producer to the consumer and back
to the producer. You can use the Network Delay Multiplier to increase or
decrease the Connection Reaction Time Limit.
Safety Tag Mapping
Controller-scoped standard tags cannot be directly accessed by a safety routine.
To allow standard tag data to be used within safety task routines, the GuardLogix
controllers provide a safety tag mapping feature that lets standard tag values be
copied into safety task memory.
