The individual elements in the diagram on the previous page are as follows (starting at
the bottom):
Element
Description
Application
The term “application” refers to the software solution for a given HVAC
application, e.g. a room fan-coil system. The application maps all
inputs, outputs and parameters in the “device”.
Device The “device” refers to the type of DESIGO RXC device in the
database of the RXT10.1 tool, and is a component of a project.
Project The “project” reflects the structure of a LON network. It contains all the
information about the existing devices and their bindings.
NVs DESIGO RX converts the parameter and I/O information into network
variables – the language used by the LON.
Each NV has a name, and comprises one or more elements.
Examples:
Name Description Elements
nvoSpaceTemp Actual room temperature 1
nciSetpoints Definition of setpoints for heating/cooling 6
For nciSetpoints, for example, the six elements represent the setpoints
for heating/cooling in the various operating modes.
NIDES binding
template
The NIDES binding templates determine which network variables are
adopted by the NIDES.RX. For this purpose, the RXT10
commissioning and service tool includes two standard templates for
each application.
Note: The NIDES binding templates should not be confused with the
templates used for bindings between the RXC controllers.
Process image
The process image in the NIDES.RX contains all the information
obtained from the “project” on the basis of all NIDES binding
templates.
RSDP Abbreviation for “RS data point”. Unit of information in the AS1000 and
MS2000 systems. The NV elements are exchanged between the BPS
and NIDES.RX in the form of RSDPs of a particular type. The RSDP
for a given NV is identified by the “SAPIM” text labels. This mapping
information is stored in the NIOPEN.ASC file or in the RxNiBps.col
configuration file for the BPS.
Example: The NV nvoSpaceTemp is transferred as an RSDP of the
type RSUZ. The associated SAPIM text label is oSpaTmp.
Infolist The Infolist contains the RSDPs for all network variables intended for
integration into the system. It is downloaded from the BPS into the
NIDES.RX at the commissioning stage.
VISONIK
data points
The network variables associated with the RSDPs are mapped to
VISONIK parameters (TEC points or link points), cf. Section 3.2.
Example:
The value of nvoSpaceTemp goes to parameter @TCR.RRTP.
Operation
The VISONIK parameters can be operated on the BPS via:
- VISOTOOL Editor / COLBAS
- the POP cards (not available for link point parameters)
