Reaction Time Limits
The following three values define the Connection Reaction Time Limit
(CRTL).
If you adjust these values, then you can adjust the Connection Reaction Time
Limit. If a valid packet is not received within the CRTL, the safety connection
times out, and the input and output data is placed in the safe state.
Value Description
Requested Packet Interval (RPI) How often the input and output packets are placed on the wire (network).
Timeout Multiplier The Timeout Multiplier is the number of retries before timing out.
Network Delay Multiplier The Network Delay Multiplier accounts for any known delays on the wire. When
these delays occur, timeouts can be avoided using this parameter.
