II/O-LIGHTBUS FIELDBUS COUPLER 2.5 MBaud CARRIER RAIL DIN 35 CAGE CLAMP CONNECTION
This buscoupler allows connection of the WAGO-I/O-SYSTEM as a slave to the LIGHTBUS fieldbus.The buscoupler automatically configures, creating a local process image which may include analog, digital or specialty modules.

The data of the modules is stored in the process image which is created automatically according to the order in which the modules are connected to the buscoupler. The bits of the digital modules are sent byte by byte. If the amount of digital information exceeds 8 bits, the buscoupler automatically starts with a new byte.
