Hello,
Im new to PLC and HMI programming. I dont have to use it much but since I come across them at work often I might as well understand how to write some basic stuff.
I set up a test bench at my desk.. Has a Panel PC that runs wonderware (I used Intouch Machine addition to program) and a controllogix PLC programmed with rslogix. I was able to get everything talking and wrote a basic start stop latch string in the PLC, exported tags to intouch and can control a pilot light on the hmi with an on and off button and see the tags toggle when online with PLC. This is a bad way because I cant figure out a way to keep the off button high.
There is a pushbutton in ITME which I have tried but have not had luck with. Gives me a few tag boxes to fill in but I dont understand what should go where.
-Tag/Expression
-Disable
-Indicator
So if I have a few tags...say Button1, Button2, Light1 where Button1 is on and Button2 is off which tags should get put into the boxes for the puchbutton? Ive tried a few different ways and cant figure it out.
Thanks in advance for any input. Also recommendations for things I can try to get working next would be cool too.
