We have a project with S7 1500 and WinCC professional (TIA).
The WinCC professional should also display some screen of another S7 1500 plc.
That PLC is from another machine builder.
The machine builder has his own TIA portal project, and will continue to use that one, and will not use a project that contains all hardware (our plc and their plc).
I now should copy the HMI srceens he has prepared in his project to my project.
What is the best way to connect to the tags of his plc?
Do I put in his plc in my project (with at least the datablok containing the variables referenced by the tags)?
What if his databloks have optimized access?
If he adds one variabele at the end of a datablok, will the old variables above still be acceseble by my HMI?
Or how should I do it : the machine builder still using his own project for the plc, and I accessing tags in his plc from my own project?
