Module 9085 Display PLC error message
The module transfers PLC error messages to the error system. The error
message texts come directly from the compiled error table (.PET) or from the
selected text file for PLC error messages. PLC error messages (except reset
errors) can be deleted by Module 9086 or by the user. However, deletion can
be disabled in the error table ("CE" column).
Up to 32 error messages can be placed in the queue.
If an error marker is assigned to the error, it is set.
System error: Is displayed without entry in the queue.

error message also occurs if no *.PET table was defined.
