Hi there. I have panel view 550 keypad . Part number 2711-k5A5 has communication port rs-232 phisically it's protocol dh-485 . Can I replace it with other one has communication port rs-485 phisically it's protocol dh-485 . It's connected to SLC 5/04 through the serial rs- 232 port (Cho) on processor module by straight forward cable with two d-shell type 9 pin sokets in the two sides .The new panel view had rj-45 communication port . What can I do to connect it with SLC 5/04 in the same protocol dh-485.  i think i must make new straight with rj45 soket in side . And the other side will be d-shell type . And edit the hmi program on panel builder soft to change the model .and download it .is that true or false? Thanks in advance.

Even if the channel 0 of the SLC -5/04 is converted into dh-485 in my machine program ?? I must need the "1761-NET-AIC " interface device ??

You will need rslinx software to establish to the communication with the PLC . Then need rslogix 500 ( the cheapest version is MICRO version ) to download your machine program into the PLC memory.  Hope this help you.
