Hello all,
I have a Panelview 550 Cat 2711-K5A5 that has one Serial port ( RS-232). Which I can talk to via my cable via DF1. Which is weird because the manual says the K5A5 is a DH485 only. Is this because someone but the wrong firmware on it or something? Or is this because someone probably replaced the back with a different part number? Also the communication screen on the panelview says it has DH+ even though it clearly doesn't have the terminal for DH+. I am asking because I would like to change it to DH485 so it can talk to an existing PLC that is already setup for DH485. I can change the PLC to DF1 but would require turning the key to rem prog, which I don't really want to do inside the plant, because then I would probably have to bypass everything and even then you never know what might happen.
Thanks
