7.1 Objects of a PLC application
7143
All objects of a PLC application are listed as subelements of the node [Application] in the device tree.
In the basic configuration a PLC application contains the following objects:
1
[Application] is the container of the PLC application
2
[Library manager] provides access to the standard and device-specific function libraries.
3
[PLC_PRG (PRG)] provides access to the program editor of the application
→ Create PLC application (→ p. 25)
4
[Task configuration] provides access to the settings of the task processing
→ Configure main task (→ p. 45)
If needed, the programmer can add additional objects to the PLC application (→ Add visualisation to a
project (→ p. 41)).
