I can't figure out why my studio 5000 code won't download to a physical HMI I'm testing it on. It was working before and it stopped working after I tried using a different code file.
I can see and connect to the PLC through both Studio 5000 and FT View. I can download different HMI screens to the physical HMI via FT view, I can even run the "Test application" feature in FT view and the simulated HMI works perfectly and I can actively change things in the code and have it show up on the simulated screen.
The .Mer file I uploaded to the HMI is the same one I can run in "test application" and despite me being connected to the HMI, it's like it won't recognize any uploaded code.
