BPS communication with BATIGYR

Function sheet

BATIGYR is a communicative individual room control system for fan coils.

Communication takes place via the BatiBUS. If a VISONIK system is used for

higher room management, the building process station (BPS) server as the

communication master.

The BATIGYR room temperature controllers and room units RCE86... control the

temperature of individual rooms and zones. The room temperature controllers

communicate with the VISONIK BPS (equipped with communication card COM1) via

the BatiBUS and the PNB interface. The BPS coordinates the individual devices and

integrates them in the higher management station.

BatiBUS

The BatiBUS is a global building field bus. It is promoted by the "BatiBUS Club Interna-

tional“ founded in 1989. The bus consists of a twisted 2-wire conductor. The

communications protocol is open and defined in different standards (NFC, CENELEC,

ISO/IEC).

In BATIGYR, the BPS has the following communication master tasks:

Tasks Examples

Providing information Operating mode, actual values, setpoints,

changeover.

Coordinating the RCE86... Grouping, master-slave relations.

BatiBUS supervision Communication between controllers and PNB.

Handling of electrical energy Controller outputs for the electrical heating coils.

Integration The room temperature controllers on the BatiBUS are mapped as data points to the BPS process image. During engineering, each controller is assigned an address and a data point, and master/slave combinations and groups are formed in accordance with the room assignment. On startup, the BPS transmits the configuration to the PNB and requests the current controller values. During operation, all changes are sent to the BPS, thus rendering their process image up-to-date at all times.

Energy handling Introduction BATIGYR was developed for energy efficient operation of fan coils. Plant example 8878Z04 Q BPS Y RCE.. The following functions are available to handle electrical heating coils: • Read energy information. • Enable electrical heating. • Limit electrical energy. The BPS supports these functions as briefly described below. However, the associated task (TSK 17) must be enabled.
