Invalid Configuration States Of The Et 200Sp On Profibus Dp - Siemens SIMATIC ET 200SP IM 155-6 DP HF Manual

5.3.8

Invalid configuration states of the ET 200SP on PROFIBUS DP

Incorrect configuration states
The following incorrect configuration states of the ET 200SP distributed I/O system lead to a
failure of the DP slave or prevent the start of data exchange.
● Number of modules exceeds maximum configuration.
● Faulty backplane bus (e.g., defective BaseUnit). No interrupt is generated when the
ET 200SP backplane bus is interrupted
● No server module
● Configuration exceeds maximum length of 1 m
● Configuration of an incorrect BaseUnit
Note
All I/O modules of the ET 200SP distributed I/O system fail (substitute value behavior) at a
station stop. However, the interface module will continue to exchange data.
Revoking the station stop (by correcting the invalid configuration state) leads to a brief failure
of the ET 200SP distributed I/O system and automatic restart.
Diagnostics
The table below shows the incorrect configurations and their diagnostics:

Slot 33 set, remaining
slots not relevant
All 33 bits set
If the BaseUnit is configured incorrectly, the channel diagnostics "Parameter assignment
error" is signaled for the respective slot. Check the parameter "Potential group" in the
parameters of the I/O module.
