The main components involved in the integration of RX into VISONIK are:
Element
Description
BLN (SDLC) Building Level Network (SDLC ring) of the VISONIK system
BPS V16
VISONIK BPS, type PRV2.00, from Version 16, with large memory
board type PVA3.02 and the CFE “RX master” application for the
integration of DESIGO RX into VISONIK.
V.24 The VISONIK BPS is connected to the NIDES via one of the two
V24 ports, TTY1 and TTY2. (Communication with the TRUNKBUS
protocol)
NIDES.RX Interface via which the DESIGO RXC devices are integrated into
the automation level. The NIDES also acts as a LON ⇔ V.24
gateway.
Each BPS can accommodate one NIDES with max. 900 RS data
points.
RXC DESIGO RXC room controllers The controller functions are
determined by downloadable application software, referred to as
the “application”.
LON
(L
ONMARK)
Local Operating Network. Connects the DESIGO RXC controllers
with each other and with other LONMARK-compatible equipment.
NVs The devices on the LON bus communicate by means of network
variables (NVs). These units of information contain the data in a
structured format based on the L
ONMARK standard.
Bindings
The “bindings” are defined at the project engineering stage and
downloaded with the application in the commissioning phase. They
identify the network variables to be exchanged between individual
LON devices. Examples:
– In the diagram above, the changeover thermostat (T), a
L
ONMARK-compatible device, transmits the changeover
command to all the defined DESIGO RXC controllers.
– All DESIGO RXC controllers transmit changes of value to the
NIDES, in accordance with the NIDES binding template.
