2.3 Mapping the RXC controllers in the RX master

As the RX master, the VISONIK BPS maps the DESIGO RXC application to VISONIK

data points and parameters as follows:

• TEC data points for HVAC functions (TEC groups and TEC rooms)

• Link points for third-party blinds, lighting and special functions

Functions

The mapped data points can be operated like normal VISONIK points. As an example,

the diagram below shows operation of a TEC group and TEC room at the BPS by use

of POP cards:

The table below provides further information on the elements in the diagram above:

Element

Description

RX n+1, etc. All LON devices are identified by a unique address before they

leave the factory (the neuron address). This is used to identify the

devices on the LON. At the engineering stage, however, each RXC

device is assigned a VISONIK address with a controller number

(RXC n+1 etc.) and a room number.

NIDES.RX The NIDES.RX converts the data received from the DESIGO RXC

controllers into RS data points, and passes these to the RX master.

(RS data points are the units of information used in the

AS1000/MS2000 systems of the Building Automation division of

SBT.)

RX master The VISONIK BPS as RXC master:

– Maps the RS data points from the NIDES to virtual TEC

structures and link points, and vice versa

– Makes available a range of functions – the RX master functions

–for coordination, control and operation

At the BPS, access is not via the network-based LON address of

the RXC controllers, but via the application-based room and group

addresses assigned in the engineering phase, as shown in the

example above for:

– TEC group 3 (@TCG3)

– TEC Room 22 (@TCR22)

Note: Access to individual controllers takes place indirectly, via the

room, as usual for TEC controllers.
