Use the software's status monitoring to see exactly where a "rung" is failing. This is the fastest way to identify a faulty limit switch or a failed relay. Conclusion
The 9.5 update focuses on and system compatibility , ensuring that programmers can work efficiently with both legacy "Series 0i" controls and the latest "30i-B Plus" series. 1. Enhanced Multi-Window Monitoring fanuc ladder iii 9.5

Identifying faults in the ladder logic or machine hardware by monitoring the execution of the sequence program.
Enter any address (e.g., Y5.0 ) and instantly see all rungs where it is used as an input, output, or set/reset.
