Creating Ladder Logic and Basic Module Program
The final step is to write a ladder program for the SLC processor,
including the 1747-SCNR scanner for slot 3 of the processor’s chassis.
After downloading the program to your processor, place the processor
into the Run mode. Your programs should now be able to read data
from the 1794-IB16 module 0000000in word I:3.3 and write to the
1794-OB16 module in word O:3.2.
The analog input data resides in words M1:3.5 through M1:3.8, while
the analog output data must be placed in words M0:3.3 and M0:3.4.
M1:3.9 is the seventh word received from the analog module. It
contains status bits for the analog I/O channels. Please refer to your
1794-IE4XOE2 analog combo module documentation for additional
details.
Example 6: Creating
Peer-to-Peer Scheduled
Connections Between
1747-SCNR ControlNet
Scanners The following example discusses how to create peer-to-peer
scheduled connections between 1747-SCNR ControlNet scanners.
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 an
SLC-5/05 in slot 0, a 1747-SCNR scanner in slot 1, 1746-OB16 module
in slot 2, and 1746-IV16 module in slot 3.
