PROFIsafe Communication Error

What does 16148 mean?

This error signifies a disruption or malfunction in the PROFIsafe communication between the safety CPU and the I/O module. This can be caused by network issues, incorrect addressing, or a faulty communication interface on the module, leading to a loss of safe data exchange.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Check the PROFIsafe address configuration on the I/O module (e.g., DIP switches) and in the safety CPU's project to ensure they match precisely.

2. 4

   If the error persists after these checks, contact ABB technical support for further diagnosis, as it may indicate a deeper hardware or firmware issue.
