What does 8448 mean?

An operation involving the Safety PLC has concluded, but it requires further action related to its switch address settings or the presence of an SD-Card in the non-safety PLC. This is a state indicating the PLC is not fully ready for safe operation until these parameters are correctly addressed and reset. Ignoring this can lead to incorrect PLC state or functionality.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Restart the Safety PLC.

  2. 4

    If the error persists, despite addressing switch address and SD-Card issues, replace the Safety PLC.
