DH-485 Comms between AB 5/02 and 5/03
DH-485 Comms between AB 5/02 and 5/03
(OP)
I was wondering if there is a quick and painless way to add another SLC 4 slot rack that's running a 5/02 CPU to my existing SLC 4 slot rack running a 5/03...
The existing 5/03 talks VB script running on a PC via the serial port. I have an 2 8 input triac cards and a 8 output triac card in this system.
Recently, I have acquired another rack with a 5/02 CPU, 2 16 DI, and a 16 DO card. I'd like to integrate the two systems.
I did visit AB's homepage. Their DH-485 overview states that a network interface adapter would be needed.
Finally my question is: Can I connect the two CPUs using the DH-485 ports and configure the programs accordingly?
Any insight and reference is greatly appreciated!!

I figured that since I had the two racks with CPU cards, I'd try to integrate the two, if it were as easy is plugging in a patch cable to both DH485 ports and changing some code in my programs...
Thanks for the tip!

You might do some homework on DH-485 networks. The only time I have used it is with a SLC 5/03. I used DH 485 to communicate to a TCP flatpanel. I am sure AB mades a cable, or give pinoust so you can make your own. You would then need to write some message instructions to handle interlocks between the 2 processors.
