Well the word or abbreviation "DO" most of the time it means Digital Output or I have seen it used in automotive plants for an action rung.
 
this is a ge series 3 controller. it is on a 1000 ton japanese shear. i have had to figure out many things in the program because they don't name things the same way we do.

---II---II-----------0-- do

this is how a simple line looks, "do" being the description of the line. i probably will need to add more lines so you can get a "feel" of the program.

thanks

Sorry I never did the 3s
Call Qaulatrol 800 784-9385 Alan Wells. It has been years since I had to call so he may not be there any more. From what I remember Qaulatrol bought the right to series 1,3,& 6. I don't think they got the 90 series. If they can't help call GE they will point you to the manuals. 877 521-5252
