I'm trying to get my S7-315 plc to communicate with my MP 377 HMI Station over ethernet but I'm having some problems. I have all the correct IP address set in each config area (I'm able to communicate to both individually with my PC) but I don't get any tag communication with the HMI. I noticed when I created the HMI station in the Step 7 manager it actually creates a new HMI project. I developed this HMI seperately in WinCC before I added anything to the PLC program. Is there a way when adding it into the manager to have it see the HMI app I've already created?
