Siemens IM 155-6 PN ST - Supply Voltage Status Compatibility; Fail-Safe Module Reaction Times

Compatibility
IM 155-6 PN ST interface module (6ES7155-6AU01-0BN0)
44 Manual, 04/2017, A5E03576904-AE
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.

Reaction times for fail-safe modules
The following maximum reaction time of the interface module must be taken into account
when calculating the reaction times of fail-safe modules:
maximum reaction time = configured update time + 400 μs (but at least 1.4 ms)
