AdvancedHMI Software

I'm just trying to get started by creating a simple "hello world" program.
My PLC is programmed so that when input 20 goes high, output 16 goes high (a lights an indicator).
In AdvancedHMI, I have a button and an indicator. The button's PLCAddressClick is set to _IO_EM_DI_20 and the indicator's PLCAddressSelectColor2 is set to _IO_EM_DO_16.
I have also tried using aliases (SENSOR/LED_WHITE) and traditional addressing (I1:20) etc.
When I click the button I get CIP Error Path destination unknown. Manually setting I20 high does not colour the indicator (but it does light my LED).
Thanks for your help.

Try to create a BOOL tag (controller scope) without the leading "_", then use that tag name in PLCAddressSelectColor2
The Micro800 has some restrictions on reading certain tags and maybe it will not allow the tag you are trying to use

It looks like my problem was that I was addressing the I/Os directly. I created a global variable and used that instead, and copied its value to the I/O in the PLC and it worked. Thanks!
