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

However, if a TRIP is activated as a result of a task overflow the application program of the PLC is

stopped as well!
