As for the processor model I do not know yet. This is a future project when $ gets availiable. The I/O will be all 1746-OBP16 and 1746-IB16. No Analog. Have been using Micrologic 1500s so I forgot that the first slot in the 5/03 is "0". I assume it will use the G file. I will be using 7 slot chassis in both. The Processor chassis will have 6 I/O cards. The remote rack will have 6 I/O cards. 1st I/O used in my program for the remote rack is I:7/0. Are you saying the SN needs to be in slot 7 of the main chassis ? And I need to use I;O/O to start ?
Slot Zero is for your CPU or ASB module. You never place I/O modules into Slot 0 of the local chassis. You may use that slot for an I/O module on an expansion chassis, but it is no longer "Slot 0" in that instance.
Yes, the SN module's Slot Number determines the range of the RIO addresses for that scanner. You cannot change this.
If you have already written a program with RIO references assigned to slot 7, then you'll need to either purchase a 10 slot chassis for your local rack or globally search and replace all of those Slot 7 I/O references in your program.
There is nothing wrong with using the older technology, if it gets the job done for you in the most cost effective manner. The only problem that you will encounter is the fact that AB jacks up the price on their older technology offerings in order to encourage users to upgrade to their newest technology.
While the hardware for a newer PLC system might cost less, you'll have to determine whether the new software purchase will offset that price difference.
Best of luck!
