Bus communication

Gassensoren werden über Bustopologie an die Gaswarnzentrale angeschlossen, und vereinfachen somit die Verkabelung. — Wiring with bus topology

to the cable shield

Bus communication between sensors and gas control panel offers many advantages:

Simple wiring in bus, star or tree topology
Connection of up to 200 sensors
Separate bus loops for redundancy are possible

Bus communication between the gas control panel and ME 1250 gas sensors is based on the Modbus standard. The gas control panels from Müller-Elektronik AG are ideally suited for bus communication with ME 1250 gas sensors. However, the protocol used is freely available and can also be read by third-party devices. Please note the Modbus register.

The maximum bus length is 1,000 meters and is therefore ideally suited for distributed applications.
