Invalid configuration states of the ET 200MP on PROFINET IO

Invalid configuration states
The following invalid configuration states of the ET 200MP lead to a short failure of the
ET 200MP IO device or prevent the exchange of user data with the I/O modules.
● More than two power supply modules (PS) inserted to the right of the interface module
● Number of modules exceeds maximum configuration
● Faulty backplane bus (e.g., additional IM present).
● I/O modules of a power segment consume more power than can be provided (overload).
In the case of an overload, the interface module provides diagnostic information,
cyclically checks the connection to the backplane bus and re-establishes it as soon as
possible.
Additional information
You can find additional information on maximum configuration, power budget and power
segments in the ET 200MP distributed I/O system

STOP of the IO controller and recovery of the IO device

STOP of the SIMATIC IO controller
Diagnostic data received from the IO device while the IO controller is in STOP state does not
initiate a call of the corresponding OBs when the IO controller goes into RUN. You have to
read the data record E00C
diagnostic data for the slots assigned to an IO controller in an IO device.
Recovery of the SIMATIC IO device
If you want to read the diagnostic data in the STOP state of the IO controller, you have to
read the E00C
diagnostic data for the slots assigned to an IO controller in an IO device.
