Building Technologies Integration von DESIGO™ RXC in VISONIK CM2Z8338en_01
Building Automation Integration overview 12.06.2006
2.4 RX master functions /
NIDES binding templates
The actual purpose of integration is to make available the RX master functions . These
either incorporate the following higher-level functions directly, or they render them
possible by indirect means:
• Management functions at the management level (DESIGO INSIGHT or VISONIK
Insight)
• Coordination and control functions at the automation level (VISONIK BPS)
RX master functions include options such as operating modes, time-switch catalogs,
summer/winter compensation, setpoint adjustments etc., as illustrated below.

Coordination and control functions
To implement the RX master functions, the BPS needs current data from the
applications. This data is available in the network variables (NV) on the LON bus.
Defining the relevant NIDES bindings provides the BPS with access to the required
data. The RXT10 commissioning and service tool includes the following facilities for this
purpose:
– Use of the pre-defined VISONIK Templates 1 and 2
– Creation of new templates by adding or omitting network variables from these
templates.
Caution: Do confuse the NIDES bindings with those used internally and between the
LON devices. They each have their own templates in the RXT10 tool.
The scope of the RX master functions depends on the following:
– The functional scope required by the client at the management and automation
levels
– The maximum allowable number of integrated controllers per NIDES / BPS
It is often necessary to reach a compromise between these two sets of circumstances.
The next topics therefore provide information about the RX master functions with the
VISONIK Templates 1 and 2, and about the additional functions available. This is
followed by a preliminary hardware list for a preliminary estimate.
