Modules
WAGO-I/O-PRO programming tool or in a higher-level control when a
connected fieldbus coupler is used.
The data of the individual electronic ballasts or sensors are not mapped in the
process image of the connected coupler/controller, but tunneled to the
application programm so the data can be analysed and processed via the
commands.
LEDs indicate the operating condition of the module and the trouble-free
internal data bus communication as well as the state of both the signal
transmission and the DALI bus.
Any Modules can be placed in any configuration when designing the fieldbus
node. Grouping of module types is not necessary.
Attention
This module has no power contacts. For field supply to downstream I/O
modules, a supply module will be needed.
Attention
The DALI/DSI Master Module cannot be used in the following combination:
LonWorks® Fieldbus Coupler 750-319 together with the WAGO TOPLON®
IF and PRIO Plug-Ins.
The module is directly supported by the controllers of the
WAGO-I/O-SYSTEM 750.
A higher-level control must be used to control the module when a coupler is
used.
This module can be used with all couplers/controllers (except for the economy
variations 750-320, -323, -324 and -327) of the WAGO-I/O-SYSTEM 750.
