Application of Module 753-646 with Programmable
Fieldbus Controllers
The function blocks provide the interface between the KNX communication
objects of the module and the IEC application.
The data formats of the function blocks are represented by data point types
(DPT's). A DPT_SWITCH function block (1 bit format) may be used for, e.g.,
switch objects (on/off). For each DPT a separate function block is available. This
enables not only the scaling, but also the individual input and output of the DPT
datasets. Depending on the application, these modules may be used in the IEC
application. The WAGO-ETS Plug-in filters the addresses of these function
blocks from the SYM_XML file generated by the WAGO-I/O-
PRO
. Thus, an
assignment between KNX group addresses and DPT function blocks can be
created in the ETS Plug-in.
In addition, the library provides a master function block controlling the
communication between the KNX module and the IEC application. The data of
the previously mentioned DPT modules are processed here.
