I am updating a project used panelview 1000, it connected a controllogx, but it not directly read/write controllogix's tag, controllogix map tags to some plc5 data file. panelview read/write these data files. but when I convert pannelview .pva to FT view's .MED, it can not connect Controllogix's mapping data files. it can read/write controllogix tag. Does it mean panelview plus can not read/write controllogix's Map plc5 data file? ( in controllox, tags is already mapping to plc5 data files). pls help. thanks a lot.
