6.1.6.10 Diagnostics in the case of in valid ET 200S configuration states
on the PROFIBUS DP
Invalid configuration states
The following invalid configuration states of the ET 200S lead to station failure of
the ET 200S or prevent entry into data interchange. These responses occur
irrespective of whether the IM parameters ”Operation at Preset <> Actual
Configuration”, ”Replacement of Modules during Operation”, and ”Startup when
Expected <> Actual Configuration” have been enabled.
• T wo missing modules
• Bus termination module missing
• Number of modules exceeds maximum configuration
• Module missing in slot 1 (in the case of the IM151-1 STANDARD,
6ES7 151-1AA00-0AB0)
• Faulty backplane bus (for example, terminal module is defective)
Note
As of IM151-1 BASIC / IM151-1 STANDARD (6ES7 151-1AA01-0AB0), IM151-1
FO STANDARD and IM151-1 HIGH FEATURE: If one module is missing (gap) and
the ET 200S is switched on, the station will not start up (see diagnosis below).
