Create PLC_PRG Module
If you want to create an initial module in a new project, the module automatically
receives the name "PLC_PRG". Execution starts from there and you can also call
other modules from there (programs, function blocks, and functions).
Initially, PLC_PRG is the only module!
Please note that until you have created a task configuration,
PLC_PRG
is the
only module that is called up and executed cyclically by the runtime system
during operation. This module is called up and executed exactly once per control
cycle.
1.
In the
