Application Examples 8-7
Application Example Program
Shown below is an excerpt from the user program. When the switch is
closed, bulbs 1 and 2 turn on and the decimal value 5555 is moved to
analog output 1 and is converted to an analog signal.
This application consists of an SLC 5/02 processor controlling local
and remote I/O.
(1)
The local I/O resides in a 4-slot chassis, consisting
of:
• 1746-OW8, 8-point AC/DC relay output module
• 1746-IA8, 8-point AC input module
Basic SLC 500 Example
Using and RIO Scanner
An RIO scanner, Catalog Number 1747-SN, resides in slot 3 of the local
chassis. The scanner controls two remote expansion chassis (one
7-slot and one 4-slot) and a RediPANEL.
1747-ASB module 1 controls the following I/O modules:
• 1746-NIO4I, analog module (2 current/voltage inputs and 2
current outputs)
• 1746-IV32, 32-point 24VDC sourcing input module
• 1746-OV32, 32-point 24VDC sinking output module
• 1746-OB16, 16-point DC sourcing output module
• 1746-OA16, 16-point AC output module
(1) An SLC 5/02 or greater processor is needed for the RIO scanner.
