  • Entry
  • Associated product(s)
You are using an input device that supports multi-touch. However, inputs via the touch-sensitive display are not recognized correctly or not at all.

Case 1 - No multi-touch in Windows Embedded Standard 7

You are using Windows Embedded Standard 7 (WS7E). Inputs via the touch-sensitive display are not recognized.

Validity
Operating system

  • Windows Embedded Standard 7 (WS7E)

Devices

  • SIMATIC Panel PC with capacitive multi-touch
  • IPC and SIMATIC Industrial Flat Panel with capacitive multi-touch

Cause
The operating system Windows Embedded Standard 7 (WS7E) does not support multi-touch. Inputs via the touch-sensitive display are only possible in single-touch mode.

Remedy
You can operate the touch controller in your SIMATIC multi-touch screen both in multi-touch mode and in single-touch mode. To enable inputs via the touch-sensitive display you have to switch the touch controller for Windows Embedded Standard 7 into single-touch mode. In single-touch mode you use the multi-touch display screen with just one finger without any multi-touch gestures.

You switch modes either via the pre-installed Panel Configuration Center or via the "SIMATIC IPC Switch Touch Mode" tool.

Panel Configuration Center
To switch to single-touch mode you start the Panel Configuration Center, select "Touch settings" and click the "SWITCH MODE" button. The touch controller will then work immediately in single-touch mode.

Case 3 - No multi-touch after long operating period

After a long operating period, Multitouch operator panels can no longer be operated or applications are terminated unexpectedly.

Validity
This behavior can occur with the devices below.

Devices

  • SIMATIC IPC477D
  • SIMATIC IPC677D
  • SIMATIC IFP
  • SIMATIC IFP ETH

Situations

  • The Multitouch operator panel is being operated in single-touch mode and there are many operations.
  • WinCC / TIA malfunction messages are configured such that with a message an event is triggered by the mouse.
  • A mouse connected to the USB port of your IPC is frequently used to operate the plant.

Cause
For Multitouch operator panels, the Hidlock.exe process ensures locking between multiple operator panels. Certain circumstances might mean that this process occupies parts of the main memory and after use does not release them again.

Remedy
Replace the "Hidlock.exe" file on the device concerned with a corrected version of the file. The corrected version of the Hidlock.exe file is available below as the download "Multitouch Fix Hidlock".

Download is authorized only for registered users.
