9 Communication

Using the serial system bus interface, the TROVIS 5179 District Heating Controller can commu- nicate with a building control system. In combination with a suitable software for process visual- ization and communication, a complete control system can be implemented.

The following communication settings are possible:

–Operation with a dial-up modem at the RS-232-C system bus interface

Basically, communication is only established automatically when errors occur. The controller works autonomously. Nevertheless, the modem can dial up to the controller at any time to read data from it or otherwise influence it, if necessary. We recommend to use the modem connect- ing cable (1400-7139).

–Operation with a leased line modem at the RS-232-C system bus interface Communication is established via a permanent connection between two leased line modems. This setup is applied for long-distance transmissions or when different signal level converters are used. The connection between controller and modem can also be established via the mo- dem connecting cable (1400-7139).

–Operation at a four-wire bus

To establish the link between controller and bus line, the signal level needs to be converted by a converter (SAMSON’s cable converter 1400-7308).
