Return Signals for Diagnostics
Definition
The “return signals for diagnostics” setting informs you of diagnostic events that
have occurred.
Sequence of the Setting
1. When the module makes a new entry in the diagnostic buffer, it sets the DIAG
bit. Whenever an error occurs belonging to any of the error classes listed in
Appendix C, an entry is made in the diagnostic buffer.
2. If the module recognizes a write job with incorrect data, it sets the DATA_ERR
bit. The cause of the error is entered in the diagnostic buffer.
3. The data are stored in the channel DB.
4. If the diagnostic buffer is read by FC DIAG or by the error evaluation of the
parameter assignment user interface, the module sets the DIAG bit back to 0.
