Discrepancy time expired

What does 3 mean?

The time difference between input signals from redundant sensors connected to a safety I/O module has exceeded the configured discrepancy time limit. This indicates a potential issue with sensor synchronization, signal integrity, or incorrect timing configuration. This is a severity 3 error.

1. 1

   Check the configured discrepancy time value within the safety application or module parameters.

2. 2

   Verify the physical wiring of the affected safety channel, ensuring connections are secure and correct.

3. 3

   Inspect the sensors connected to the channel for proper operation, alignment, and response time.
