This system block is only implemented as of software version V 8.x.
The system block DCTRL_DriveControl is used as interface between application and operating
system for device control:
·
TRIP−SET ( ^ 2−35) )
·
TRIP−RESET ( ^ 2−35) ).
In addition, the SB indicates the DrivePLC status for diagnostics purposes.
The process image is created in a fixed system task (interval: 2 ms).
Tip!
The inputs of the SB DCTRL_DriveControl only influence the internal device control.
If, for instance, a TRIP is activated by the operating system or the function block L_FWM() the
application program is not be stopped.
However, if a TRIP is activated as a result of a task overflow the application program of the PLC is
stopped as well!
