I have experience programming in an environment where the HMI and the PLC are all in a single software environment. Meaning all the tags and variables are shared automatically.
Can someone explain the basic mechanics of using separate HMI and PLC software packages. How do they share tags etc. Do you set up an exchange of some type for every instance where you need to share data ?
I just need an overview of how this works.....
