Electrical installation
4.10 Signal connections
Note
Address 126 is used for commissioning. Permitted PROFIBUS addresses are 1 ... 126.
When several Control Units are connected to a PROFIBUS line, you set the addresses
differently than for the factory setting. Each PROFIBUS address in a PROFIBUS line can
only be assigned once. Either set the PROFIBUS address in absolute terms using the rotary
coding switches – or selectively in parameter p0918. Each change made to the bus address
is not effective until POWER ON.
The currently set address of the rotary coding switch is displayed in parameter r2057.

The LAN (Ethernet) interface does not support Auto MDI(X). For this reason, only crossover
cables may be used to connect devices.
For diagnostic purposes, the X127 LAN interface features a green and a yellow LED. These
LEDs indicate the following status information:
