Bezel LED(s)

[drdeason]

I have a T10A, and it looks like there are LEDs in all 4 corners of the bezel; are there? If so, is there any way to control them from a PLC?

You can use the system tags to control the LED's.

I thought there's only one LEDs that can be used in system tags. In the upper left corner?? or new hardware is available?

Best regards

Some HMI's have multi-LED's and not all of them allow the customer to control them. The system tags do not changed based on the type of HMI you have. You should refer to the hardware documentation of the specific HMI and find out the capabilities of the HMI you are using. Then you can use the appropriate system tags to control the LEDs.
