Why are the logic rungs of a Micro1 PLC not displayed in 8010SFW30 program?

Published date: 06 July 2018

If the program was originally written with the 8003 PR3 hand held programmer and the author didn't follow the rules for the SFW30 software, the rungs will not be displayed on the computer screen. A program with this problem can be uploaded and down-loaded. The program can print the ladder logic for rungs that follow the rules, all other rungs will be printed in Boolean format.

Note: The Micro1 PLC was obsoleted in 2009 and the recommended PLC replacement would be the M221.
