Incorrect module configurations of ET 200S on the PROFIBUS DP

Invalid module configuration states
The following incorrect module configurations of ET 200S lead to station failure of the ET
200S or prevent entry into data exchange. These responses occur regardless of whether the
IM parameters "Operation at set <> actual configuration", "Replace modules during
operation", and "Startup at set <> actual configuration" have been enabled.
● Two missing modules
● Terminating module missing
● Number of modules exceeds maximum configuration
● Backplane bus fault (for example, defective terminal module)
Diagnostics
You can recognize all faulty module configuration states based on the following diagnostic
information:
All 12 bits set
IM151-1 BASIC interface module (6ES7151-1CA00-0AB0)
