Status of the supply voltage
Load voltage diagnostics are only valid if the station started up with a valid and complete
configuration.
• For modules in the following table without a parameter assignment, the status of the
supply voltage is always signaled as "1" regardless of the actual status of the supply
voltage.
• If a potential group is exclusively made up of modules without parameter assignment
from the table below, no group diagnostics "Missing supply voltage L+" is signaled for this
potential group.

Response times
The response time of the IM 155-6 PN ST is made up of:
• Backplane bus cycle time
• Operating system processing
Note
Validity of the formula
The following formula applies to the ET 200SP backplane bus.
The formula does not apply to the ET-Connection bus.
Backplane bus cycle time
The backplane bus cycle time is the time the interface module requires to output new output
data, read new input data and then copy the data to the PROFINET send buffer.
The backplane bus cycle time is the result of the update time configured for the interface
module as IO device and amounts to at least 1 ms.
• If the configured update time ≥ 1 ms, the backplane bus cycle time is equal to the
configured update time.
• If the configured update time < 1 ms, the backplane bus cycle time is the product of an
integer multiple of the configured update time.
