You can change the volume and the brightness of the UniStream PLC in one of the following two ways:

1. With actions.

Change Volume (range: 1-100): When the trigger bit turns ON, the volume increases to the level in the linked register. This bit is reset by the system.

If the register value is out of range:

– Lower than 1: Volume set to 1

– Higher than 100: Volume set to 100

Change Brightness (range: 10-100):  When the trigger bit turns ON, the screen brightness increases to the level in the linked register. This bit is reset by the system.

If the register value is out of range:

– Lower than 10: Brightness set to 10

– Higher than 100: Brightness set to 100

2. Through the HMI screen via UniApps.

Press the upper right corner of the PLC for 8 seconds.
