Hello,
We have some systems which utilize TIA Portal V13 (CPU S7-1200). We currently have a Siemens HMI (TP-700 Comfort) on the system. I am looking to add an additional HMI to do some statistical gathering. I am contemplating a Proface. My question is this: Must the HMI be added to the TIA project as well? I tried importing tags into GP ProEX (Proface software) but was unable to. Any other PLC I have worked with never required addition of an HMI to the project itself, but from what I have read and heard, any HMI's must be added to the TIA project. Is this the case?
