6.6.10 Diagnostics in the case of invalid ET 200S configuration states
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.
• Two missing modules
• Terminating module missing
• Number of modules exceeds the maximum configuration
• Module missing in slot 1 (in the case of the IM151-1 STANDARD,
6ES7151-1AA00-0AB0)
• Faulty backplane bus (for example, terminal module is defective)
Note
As of IM151-1 BASIC/IM151-1 STANDARD (6ES7151-1AA01-0AB0), IM151-1 FO
STANDARD, and IM151-1 HIGH FEATURE: If one module is missing (gap) and
