Synchronous Input Data Refresh Error

Hva betyr A10101 ?

This word (A10101) will contain the value '0001 hex' when the CPU Unit fails to receive synchronous input data from a Synchronous Unit within the specified time window. This indicates a loss of synchronization or communication with the connected unit. A value of '0000 hex' indicates normal operation.

• Failure of the CPU Unit to receive synchronous input data from a Synchronous Unit.
• Synchronous input data not transmitted or received within the configured synchronous operation cycle time.
• Disrupted communication link or physical connection issues between the CPU and the Synchronous Unit.

1. 1

   Verify the communication link and physical connections between the CPU Unit and the Synchronous Unit for integrity.

2. 2

   Check the synchronous operation cycle time setting in the PLC Setup (A10102) to ensure it is adequate for reliable data reception.

3. 3

   Confirm that the Synchronous Unit is transmitting data correctly and within the expected timing parameters.
