Hi all,
I'm working on a project replacing a failed SLC5/03 with a new ML1400. I've gotten the program updated and working, all the IO changed over, but have a couple of questions about DH485 connectivity.
The existing system uses a SLC5 hooked in via DF1 FDX to a 1747-AIC, and from there DH485 to a PV900 about 2000' away. I'm having trouble finding a manual for the 1747-AIC - I'm mostly just trying to figure out how 'active' the 1747-AIC is and if I can just use a 1763-NC01 on the ML1400 (CH0, configured for DH485) to communicate or if I'm going to need to make additional changes in the program.
As far as I can tell, it's a dumb converter but I want to make sure before I get on site again. If the 1763-NC01 would work, is there anything that needs to be done on the program other than setting CH0 to DH485?
Unfortunately, it's not feasible to play around with the PV900 until I'm there to do the swap, so I'm already figuring there will be a fair amount of time working on that part of the integration.
Any knowledge someone could share would be helpful on this - I'm leaning towards it being a dumb converter as the only manual I've been able to find is simple hook-up data and doesn't mention any configuration.
Thanks!
