10.1 Changing the Configuration with the WBM
The “CFG/RST” button is on the left side. The button calls up the Web-Based
Management WBM to configure the device. The button must only be pressed
using a pointed non-metallic object.
During the visualization run-time, the WBM is called up.
When starting up the device (Power ON), the autostart list is stopped and the
device only starts the WBM. The button is not used to make any changes to the
settings.
10.2 Calibrating the Touch Screen
When connecting the panel to a WAGO controller, the touch screen is calibrated
via the WBM. Select “Display” > “Touchscreen Calibration”.
Figure 14: Touchscreen Calibration
Calibrate the touch screen carefully. To avoid parallax errors, use the display
from the position from which you will use it later. When possible, use the input
tool (finger, touch stylus) that you will use later in operation.
You should then set the calibration to “OFF” in the WBM. Otherwise, the
calibration screen is then displayed each time the device is started. See section 7
“Commissioning” > “Configuring in the Web-Based Management (WBM)” > “WBM
Page ‘Display>Touchscreen Calibration’”.
10.3 Cleaning the Touch Screen
Because the touch screen is touching sensitive, it must be disabled for the
duration of the cleaning. There are two options to start cleaning mode:
• In the WBM via the “Function Menu” quickstart button from the “Start
Clean Display” menu item
