Controlling Brightness on a T50 Mobile Panel (6PMT50.101E-16B) Logically

Hello everyone,

I recently acquired a T50 mobile panel (model number 6PMT50.101E-19B) and I’m looking to control its screen brightness programmatically.

In the user manual, I found a potentially relevant section that mentions controlling brightness using AsRfbExt, as shown in the image below:

The reason why this approach is interesting is that I need to be able to dim the panel to lower han 20% brightness.

I have a few questions regarding this:

  • From my understanding, AsRfbExt interacts with a VNC application. Does this mean that the power panel needs to be actively connected to a VNC server for this method of brightness control to work?
  • Has anyone in the community had experience using this AsRfbExt library and could offer some guidance or point me towards relevant resources?
  • If a VNC connection is required for brightness control via AsRfbExt, will I still be able to simultaneously use a web HMI hosted on the PLC’s webserver?

I’ve also come across an example for AsRfbExt using ANSI C, but I find the associated documentation to be somewhat lacking.

My hardware setup includes:

  • Panel: 6PMT50.101E-19B
  • PLC: X20CP0484

Thank you in advance for any assistance you can provide!

You can use the OPC UA server functionality on the Power Panel. It has a method SetBrightnessUnlimited, which allows to set the screen brightness in the range from 0% to 100%
