This page is WAY out of date now .

The concepts are the same but the version of classicladder is different and HAL has matured.

Go ahead and look at this page, then go here-> ClassicLadder

This command changes the ini file that emc will use to whatever filename you put in there. This ini file in turn calls a different hal file. That file demo_step_cl.hal starts up the real-time ladder interpreter and connects it to hal and the emc. This hal file also causes classicladder to read a ladder logic file named demo_step_cl.clp that provides the logic needed to get this version of emc into and out of estop properly.

When you started emc2 using the command "sudo scripts/emc.run scripts/step_cl.ini" all of the widgets needed to edit ladder are available to you. Move the ladder display to the run you want to edit. This can be a bit tricky. There are little gray lines across the display between rungs.
