13. Diagnostics, troubleshooting and aids
All error codes are listed in the following. If you use the data blocks with
extended configuration
in the configuration
software for your control system, the error code is output in the corresponding byte. In the
standard configuration
, only
a corresponding error status bit is set and the system indicates the error via the diagnostics LEDs.
Important!
The error code given in the tables below is sequential and starts with 0x01. You must add any upstream
error codes from PROFINET or the control system to the ERROR codes stated. For PROFINET, the
offset to be taken into account is 0x100.
Most messages are also displayed on the devices.

13.3. Resetting system to factory settings (factory reset)
You can reset the device using one of the following methods:
Ì
With the aid of the configuration software for your control system (this resets only the Profinet portion).
Example for Siemens TIA-Portal: in the “Online & Diagnostics” dialog box
Ì
With the aid of the DIP switches in the bus module MBM (this resets the overall system including the MLI topology).
Procedure: Switch off system, set “RST” DIP switch to “ON” position and restart system. If DIA and MAINT flash alter-
nately, switch the system off, set the “RST” DIP switch to “OFF” position and restart the system.
Ì
Check the safe function of the safeguard and, if necessary, other safety functions after every factory reset
