Siemens SIMATIC NET PROFIBUS manual Ordering Data, Profibus ILM

Active Components for Wireless Networks

Functions

The ILM allows a wireless link with PROFIBUS slaves at a maximum range of 15 m. Communication with several slaves is possible. Interruptions in transmission are detected and indicated by LEDs and the signaling contact. If there is a deterioration in the transmission quality, this is indicated by LEDs and the signaling contact before data transmission is stopped.

The module can be operated in daylight thanks to an integrated filter. When installing the Infrared Link Module, make sure that there is a free line-of-sight link between the modules.

When using several ILM transmission paths, avoid one path interfering with another by including partitions or maintaining minimum clearances.
