C-more Micro HMI: Controlling Backlight Color from AutomationDirect

Since the C-More Micro is the master, we just need to tell it where to get the data it needs to control the Backlight Color. In this example we have told the C-More Micro to watch this SCREEN NUMBER TAG. The backlight color is offset two TAGs from that. So if the screen number is at address DS100, then the backlight color is t the TAG that is at DS100 plus 2. Screen Colors are 0 thru 5, with 6 being OFF and 0 being the current color – that is the color the screen was originally programmed to be. So lets try a couple here … Let’s change it to a 1 and that’s GREEN. Let’s change it to a 2 – that’s lime. Let’s change it to 3, there’s yellow. Four amber or orange, and 5 is RED. Again, 6 being off and zero says go back to being whatever screen color this was originally programmed for – in this case GREEN. Lets see how to set this up. You can reach that from the Navigation window’s function TAB PLC-Panel or from the Setup Menu: PLC -> Panel. We want to configure the PLC to Panel control over the backlight color. To do that we need to setup a TAG where the PLC can put the screen number. The C-more Micro then looks at that TAG which is DS100 plus 2 for the backlight color IF this checkbox is enabled. Note that there is a little reference sheet down here telling you that at this address it will change the backlight color and here are the colors. Again, 6 being off, and zero being the screen color that was originally programmed. So let’s take a look at that one more time. Bring up our simulator…. Since the screen number feature was turned off, we are only seeing the one address – the DS100 plus 2 – the two word offset. 0 Says use whatever screen color it is programmed for, 1 is green - that won’t help us any – and 3 – that’s yellow, and 5 that’s RED. 6 turns the backlight OFF and 0 says go to whatever backlight color was originally programmed That’s all there is to setting up Backlight control – be sure to check out the other videos in this series.
