Hi,
I have an SLC 5/04 (541) in a 10-Slot rack with the following hardware installed :-
1746-BAS in Slot 1
3150-MCM (Prosoft Modbus) in Slot 2
1746-IB16 in slot 4
(Slot 5&6 spare - reserved for 1746-IB16)
1756-OW16 in slot 7
(Slot 8&9 spare - reserved for 1746-OW16)
I am just about to install a 1746-SN in slot 3
I want to have a remote 7-slot chassis hold 2x1746-IB16, 1x1746-OW16 and 3x1746-NI4, as well as the 1746-ASB.
I have not used Remote I/O before and am trying to digest the manuals for the SN and ASB modules. It's starting to make some sense, but I have a few of questions that I'd appreciate some help with please....
1. Hopefully, there are no glaring issues with the proposed configuration above?
2. The distance between the racks will be ~100m, I'm expecting to run the link as fast as I can - 230K, I take it that will be OK in terms of distance?
3. I know that the link can only run at the speed of the slowest device, with just the processor and the remote rack, that should not be a problem, but if I add a PV-300, does that change the maximum speed that's possible?
4. I'm a bit confused about the configuring the 1746-SN - particularly with the analogue modules in the remote rack. (The processor is Series B Rev 3, OS401 Ser C FRN 8). From what I've read so far, the discrete modules appear to be fairly straight forward, but the analogue modules appear more complex.
I'd appreciate a few pointers on the roles of G Files, M files, block transfer commands etc. in the context of how I get the analogue data to the processor.
Is there any preferred order for the discrete and analogue modules in the remote rack? Does placing them one way or another help reading/writing to them more efficient?
In the G file configuration, do I create one group for all modules, e.g., something like Group 0, 3/4 Rack, for 6 modules - I'm assuming the ASB in slot 0 of the remote rack, so would potentially have 6 I/O modules. Does the number of "primary devices" include those that will be accessed by both discrete transfers and block transfers?
I think that the analogue modules need block transfers to work?
Thanks a lot for any help - I am busy RTFM'ing, but it's proving quite difficult to get my head around the concepts
regards
Dave
