Functional principle

The programmable BL20 gateways can be

used as autonomous PLCs or as decentral

PLCs in a network interconnection for a fast

preprocessing of signals.

BL20 gateways are the head component of

a BL20 station. The BL20 extension modules

communicate over the internal module bus

with the gateway and can be configured independently of the fieldbus protocol.
