Creating a Ladder Program
The final step is to write a ladder program for the SLC processor,
including configuring the 1747-SCNR scanner for slot 3 of the
processor’s chassis.
1 . After downloading the program to your processor, place it into
the Run mode.
2. Set the Run/Idle bit (O;e.0/10, where e=slot number of your
1747-SCNR scanner) to a 1.
Your program should now be able to read data from the
1746-IA16 in word I:3.3, write to the 1746-OB16 in word O:3.2
and read data from the 1746-IV16 in word I:3.5.
Example 2: Configure the
1747-SCNR Scanner with
the 1746-NIO4V Analog
Input/Output Module The following example discusses how to configure the 1747-SCNR
scanner with the 1746-NIO4V combination analog input/output
module.
Hardware Setup
The hardware setup for this examples includes a computer with
RSLogix500, RSLinx, RSNetWorx for ControlNet software, and a
1784-KTCX15 interface card. The chassis configuration includes a
1747-ACNR15 module in slot 0, 1746-IA16 module in slot 1,
1746-OB16 module in slot 2, and 1746-NIO4V module in slot 3.
Configure the ControlNet Network with RSNetWorx
for ControlNet Software
Follow the procedure below to configure the ControlNet network
using RSNetWorx for ControlNet software.
1 . Start RSNetWorx for ControlNet software by double-clicking its
icon.
