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® PRIO plug-in, all 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® PRIO application, unused variables should not 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® PRIO, all defined configuration variables are ready to be linked with CPs (Configuration Properties) just like the PFC variables.
