On all AB controllers, all of the comm ports have equal support for messaging and online upload/download and monitoring. The only difference is the protocol and electrical characteristics. Channel 0 can be either DF1 or DH-485 protocol.
Great job, Mr. PLC Prof. I enjoy your videos every time I view them. Thanks again for your continued work. I have been away from working on AB-PLC units for most of 10 years, so all this viewing is very helpful. Thanks again. When I view the part 3 of RSLinx I will present a question. Until then I will see if you address it when I view all of these.
