The table below shows all modules that do not support a station configuration with more than
32 I/O modules:
Table 6- 1 Incompatible modules with functional status
AI 4xI 2-/4-wire ST 6ES7134-6GD00-0BA1 002
AI 4xRTD/TC 2-/3-/4-wire HF
Status of the supply voltage
Load voltage diagnostics are only valid if the station started up with a valid and complete
configuration.
● For modules without parameter assignment in the following table, the status of the supply
voltage (status byte of the server module) 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.
Resetting an interface module to factory settings via the RESET button
There is a special operation for interface module IM 155-6 PN/2 HF to reset it to the factory
settings using the Reset button.
The supply voltage to the interface module must be switched on.
