Accessing Input and Output Safety Connection Reaction Time Limit
The Connection Reaction Time Limit is defined by these three values:
By adjusting these values, 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 are placed in the safe state (OFF). To view or
configure these settings, follow these steps.
1. In the configuration tree, right-click your I/O module and choose
Properties.
2. Click the Safety tab.
Value Description
Requested Packet Interval (RPI) This is how often the input and output packets are placed on the wire (network).
Timeout Multiplier The Timeout Multiplier is essentially 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.
