Functional principle

BL20 gateways are the head component of

a BL20 station. They are designed to interface the modular fieldbus nodes to the higher level fieldbus (PROFIBUS-DP, DeviceNet,

CANopen, Ethernet).

All BL20 electronic modules communicate

over the internal module bus, the data of

which is transferred to the fieldbus via the

gateway, so that all I/O modules can be configured independently of the bus system.
