Input Size Mismatch

What does F100:09 mean?

This CoE object indicates that the length of the input data does not match the input data length calculated from the safety logic. This discrepancy points to an incorrect configuration of the EtherCAT master or the safety project regarding the expected input data size for the EL6900, which can prevent the safety logic from running correctly.

• The size of the input data configured in the application does not match the expected size from the hardware or communication interface.
• Mismatched input mapping between the PLC and the physical I/O modules.
• Incorrect parameter P1-33 (Input configuration) in the safety device.

Click steps to track your progress.

1. 1

   Verify the configured input data length for the EL6900 in the EtherCAT master configuration (e.g., TwinCAT System Manager).

2. 2

   Compare the configured input data length with the length calculated and expected by the compiled safety logic project.

3. 3

   Ensure that the TwinSAFE safety project has been correctly compiled and downloaded to the EL6900, matching the current hardware configuration.
