application program excerpt
The following is a very basic SLC 500 remote I/O application example.
This application consists of an SLC 5/02 processor controlling one
local and one remote chassis of I/O.
(1)
The local I/O resides in a
4-slot chassis, consisting of:
Basic SLC 500 Example
Using and RIO Scanner
•
1746-OW8, 8-point AC/DC relay output module
•
1746-NIO4I, analog I/O combination module (2 current/voltage
inputs and 2 current outputs)
A RIO scanner, Catalog Number 1747-SN, resides in slot 3 of the local
chassis. The scanner controls one remote 7-slot chassis using one
1747-ASB module.
The 1747-ASB module controls the following I/O modules:
•
1746-IA16, 16-point 100/120 VAC input module in slots one,
two, and three
•
1746-OA16, 16-point AC output module in slots four, five, and
six
(1) An SLC 5/02 or greater processor is needed for the RIO scanner.
