The Beckhoff Bus Terminal system

Up to 256 Bus Terminals, with 1 to 16 I/O channels per signal form
The Bus Terminal system is the universal interface between a fieldbus system and the sensor / actuator
level. A unit consists of a Bus Coupler as the head station, and up to 64 electronic series terminals, the last
one being an end terminal. Up to 255 Bus Terminals can be connected via the K-bus extension. For each
