3.2 Functions for the DESIGO

RXC

applications

The RX master functions in the BPS are implemented by mapping VISONIK

parameters to controller network variables. As can be seen in subsection 2.2, the

VISONIK parameters are first transmitted to the NIDES.RX and only then mapped to

the network variables. The following diagram shows the process from the functional

viewpoint.

TRUNKBUS

The parameter values in are exchanged as RS data points in the trunkbus protocol via

the V24 link between the BPS and NIDES.RX

Network variables are exchanged on the LON side. This involves the connection of

controller inputs (nvi) to NIDES.RX outputs (nvo) and vice versa.

These connections, or “bindings” can be drawn in the Binding Template Editor of the

RXT10 tool. They are already defined in the standard VISONIK Binding Templates.

For the HVAC functions, the parameters used are primarily those of the TCR and TCG

points. For lighting and blinds, the link point parameters EMV (Event Main Value), FBV

(Feedback Value) and ERSTA (Error State) are used.

For each RX master function, the mapping of the relevant parameters to the associated

network variables is described in the subsections which follow. The first subsection

explains the symbols used, with “Intranet room operation” as an example.

With integration into VISONIK, it is also possible to integrate network variables for third-

party devices. However, the VISONIK system will not recognize the associated

applications. The general procedure for the integration of all kinds of network variables

is described in Section 4, Engineering, subsection 4.11, Integration of single

parameters.

The “Trunkbus protocol” and the “RS data points” are concepts associated with the

MS200 system (see also 4.2). Each RS data point represents a single NV element.

However, the user does not need to be concerned with this.
