3.1 Bus interface
In common building services management systems GLT as well as in other areas of automation en-
gineering a variety of field buses are used. Bender systems like EDS470/473, RCMS470 and MEDICS
communicate with each other via the Bender Measuring Interface BMS.
Our protocol converter FTC470XDP (gateway) is intended to connect this BMS interface to the
PROFIBUS DP. For that purpose, the FTC470XDP is connected to the PROFIBUS DP network in the
function of a PROFIBUS DP slave.
