3.2 Application of the FTC470XDP
The connection of Bender systems to the BMS bus and to the PROFIBUS DP by means of the
FTC470XDP can become necessary for several reasons:
A PROFIBUS DP device is expected to respond to an event in the BMS world.
A BMS interface device is expected to respond to an event in the PROFIBUS DP world.
The BMS interface data and the PROFIBUS DP data are intended to be indicated and evaluated
centrally on a personal computer using PROFIBUS DP software.
The BMS interface data are to be indicated in the software of a building services management
system incorporating a PROFIBUS DP interface.
The configuration of devices of the BMS side is to be carried out via a personal computer with
PROFIBUS DP interface.
The control of certain BMS interface activities is to be carried out via the PROFIBUS DP.
3.3 Restrictions
Some Bender devices like TM operator panels or PRC1470 use in addition to the internal interface an
external interface capable of connecting such devices to extended networks. This external interface
cannot be addressed by the FTC470XDP. In BMS systems including TM operator panels or PRC1470
these components can only communicate with the FTC470XDP via the internal interface.
If FTC470XDP is operating to the internal interface of TM operator panel or PRC1470, a Master take
over cannot take place. In this cause only the functions described on page 17 can be used.
If the FTC470XET is operated on the internal bus of a PRC1470 or TM operator panel, the protocol
converter cannot take over the Master function. When operated in combination with these devices,
only Slave functions can be used. For details see “FTC470XDP communicates with the PROFIBUS DP
Master as ’BMS Slave’” on page 17.
Please note that some BMS Masters cannot return their Master function
