Rockwell Automation 1747-SCNR ControlNet Scanner Module Reference Manual - Manual (Page 105)

Application Examples E-27
You have successfully configured your two connections to read/write
data between the SLC processor and the remote ControlNet chassis.
All that remains is to save the configuration to the network keeper,
which in this case is the 1747-SCNR scanner.
1 . Click the Save icon or choose the File menu and then Save.
You are prompted to Optimize and re-write schedule for all
connections.
2. Click OK.
3. Click YES to the warning message.
Your network configuration information is now written to the
network keeper.
The display on the front of your 1747-SCNR scanner should
show an image of a full glass next to the word I/O. This
indicates that all configured connections have been successfully
downloaded to the scanner. In addition, the A and OK LEDs are
solid green and the B LED are off, unless you are using the
redundant media option, which is not being used in this
example. The 1747-ACNR15 module is displaying that it is active
(ACTV) and its LEDs are solid green for A and OK and the B
LED is off.
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.
• After downloading the program to your processor, place it into
the Run mode.
Your program should now be able to read data from the
1746-IA16 in word I:3.3 and write to the 1746-OB16 in word
O:3.2. The analog input data and channel status will reside in
words M1:3.3 and M1:3.18, while the analog module
configuration data must be placed in words M0:3.3 and M0:3.14.
