B. Drucker, Scanner oder Barcode-Leser Functional principle BL20 electronic modules are plugged into the purely passive base modules which are used for connection of field devices. Maintenance is significantly facilitated due to separation of the connection level from the module electronics. Furthermore flexibility is enhanced because the base modules provide a choice of tension spring or screw connection technology. The electronic modules are completely inde- pendent of the type of higher level field bus through the use of gateways.
