Note
IM 155-6 PN ST (6ES7155-6AU00-0BN0) with firmware version V4.1
You can upgrade the previous version of the IM 155-6 PN ST interface module (6ES7155-
6AU
00
-0BN0) to the firmware version V4.1. In this case configure the module as IM 155-6 PN
ST interface module (6ES7155-6AU
01
-0BN0) with firmware version V4.1.
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.
