7.1 Objects of a Standard PLC application
43100
All objects of a Standard PLC application are listed as subelements of the node [Application] in the
standard area of device tree. In the basic configuration a Standard PLC application contains the
following objects:
[Application] is the container of the Standard PLC application
[SafetyApp_Mapping] is a helper application for the data exchange between Standard PLC and the fail-safe PLC
→Set interval of the data exchange (→ S. 85)
[Bibliotheksverwalter] provides access to the standard and device-specific function libraries
[DataFromSafe] and [DataToSafe] are global variable lists for the data exchange between the Standard PLC and the
fail-safe PLC.
→Data exchange between standard PLC and fail-safe PLC (→ S. 82)
[PLC_PRG (PRG)] provides access to the program editor of the standard application
→Create standard PLC application (→ S. 48)
[Taskkonfiguration] provides access to the settings of the task processing
→Configure main task (→ S. 69)
