PLC Programming Considerations
Appendix A
A-11
PLC-5/25 Series A, rev. D or later
Other PLC-5 processors released after the date of this publication also
support this function.
1. Put the PLC controller in the Program Mode or the Remote Program
Mode.
2. From the first screen of the software, press F1–Online Prg/Doc.
3. Press F8–Monitor File.
4. Create an Integer File for I/O Status—two words are required for
each rack.
Press F7–General Utility
Press F1–Memory Map
Press F6–Create DT (data table) File
Example: Entering N10:13 creates an Integer File 10 with words
(0–13). This is 2 words for each of the 7 remote racks that may be
connected to a PLC-5/25.
5. Assign the Integer File created in step 4 to the I/O Status.
From the General Utility screen, press F2–Processor Status.
Enter the Integer File number into the area called I/O Status
File—located in the lower center area of the screen.
Example: If you created File N10:13 as in the example in step 4, you
would enter 10.
6. Configure the processor to recognize all of the remote I/O devices
connected to the remote I/O link.
From the Processor Status screen, press F3–I/O Status.
Press F1–Autoconfigure.
This will check all of the devices connected to the remote I/O link, set
the proper bits in the I/O status file, and display the setup on the I/O
status screen.
