I/O Module Checksum Error

ABB · AC500 Function Block Libraries

What does 16147 mean?

This error indicates that a checksum calculation for the safety-relevant configuration data (I-parameters or F-parameters) within the I/O module has failed. This signifies data corruption or an incorrect configuration download, which can compromise the integrity of the safety function and lead to unsafe conditions.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Re-download the safety configuration to the I/O module, ensuring a successful transfer and verification of all parameters.

  2. 4

    If the error persists after verifying and re-downloading the configuration, consider replacing the I/O module as an internal hardware issue might be present.
