Requirements

The function block FB_TcTouchLock_AcquireFocus and the TCTouchLock service can only be used under Windows 7 and Windows 10. The function is supported by multi-touch Control Panels and Panel PCs from the PCT-V03 touch screen version. The functionality is not available with other touch panels.

The touch screen version of your device can be found on the name plate (see Fig. 3).

The devices to be controlled must be connected to the same IPC. In addition, the use of an input option for requesting/releasing the touch focus, which can also be used with a locked touch screen, must be taken into account. Also consider a hardware input for unlocking.
