Tab. 3-5: Presetting addresses in the template file Template_750-819.pro
This template can be upgraded and modified at any time.
Once the IEC 61131 application programmed in WAGO-I/O-PRO 32 has been
compiled, all declared variables can be stored in a Symbol-file (SYM-file).
After downloading the SYM-file in the WAGO TOPLON
variables are ready to be linked with network variables.
Note
Given that all variables are automatically imported from the template into the
standard WAGO TOPLON
be deleted from the template in order to achieve a better clarity.
3.2.6.2.3 Addressing the configuration variables
Variables used for external configuration via the LON fieldbus are absolute
addressed in double flag words. The address range begins with %MD1792 and
has a capacity of 128 variables.
After downloading the SYM-file into WAGO TOPLON
configuration variables are ready to be linked with CPs (Configuration Proper-
ties) just like the PFC variables.
3.2.7 Starting-up LON fieldbus nodes
The general procedure for starting up a WAGO LON fieldbus node with the
fieldbus controller 750-819 is described step-by-step for TOPLON
the brief instructions WAGO TOPLON
002 part 7).
These should form a guideline for further projects.

Attention
This description is given as an example and is limited to the execution of a
local start-up of an individual LON fieldbus node with TOPLON
3.2.8 Programming the PFC with WAGO-I/O-PRO 32
Due to the IEC 61131 programming of the LON fieldbus controller
750-819 you have the option to use the functionality of a PLC.
