Forgot to ask, RS500 program making ladders

[dbonniwell]

#2 ladder is Main, how are ladders 3 on up created with in the program?

 

[randylud]

Add them under program files and they become sub-routine files!

 

[OkiePC]

More specifically, in the project tree (left pane) right click on "Program Files" and click "New...". You'll be prompted for a file number, name, and description. This cannot be done online.

You also need to add rungs with JSR instuctions that call the additional program files in file #2. File 2 is the only file the PLC will scan without being called by a JSR.

Just in case

All the above is correct unless you're using a ML1000.

 

[TConnolly]

The ML1000 comes with 16 predefined ladder files. You cannot add more and you cannot delete them. Ladder 3 is reserved for the fault routine, 4 for the high speed counter interrupt routine, and 5 for the selectable timed interrupt routine (though if you dont use the HSC or STI you can use them for something else) and 16 is reserved for a debug routine. You also cannot change the data files or enlarge them.

I try to stay away from the ML1000 - The ML1200 is only a few bucks more and well worth it for the functionality.

As an aside to this has anyone ever come across a programm to actually make ladders. The type you use to climb I mean. Just interested if there is a ladder ladder program out there. Regards Alan

Guess we could always make one? Sounds like a good project!

I would love to see the safety inspection routine on that project
