Using the Error Log
Error Log Concept
The CS1/CJ1W-PRM21 PROFIBUS Master Units are equipped with an error
logging mechanism, which will internally store error events. Most of the errors,
which are stored in the Unit’s Error Log are stored in volatile memory, i.e.
when power to the Unit is switched off, the errors are lost.
Severe errors however, are also stored in non-volatile memory, i.e. these error
reports are still available after cycling the power down and up again. The
errors which can be logged are listed in section
4-3-2 Error Codes
.
The CS1/CJ1W-PRM21 PROFIBUS Master Units can log up to 80 error
events, 16 of which can be logged in non-volatile memory.
Reading New Errors from
the Error Log
If a new error event is logged in the Error Log of the Unit, a bit flag can be
evaluated by the user, through the CS1/CJ1W-PRM21 Master DTM Diagnosis
User Interface. In order to view the bit flag, perform the following actions.
