If you need such big sequences, you should consider splitting it into 2 or more sequences, or using not only an IND, but also a DEP sequence etc... .Splitting it into 2 sequences is common practice at our site....Have 2 seq talk to each other, send command and wait for confirmation from 2nd seq etc.... Otherwise review the code and try a different approach, using more subroutines, using an include sequence etc.... I'm not sure about this but I think it's the number of lines which determines the size of the sequence. You can put multiple lines of code all on line seperated by ; ie BO001 := FALSE;BO0002 := FALSE; in stead of BO0001 := FALSE; BO0002 := FALSE; Like i said I'm not sure if it makes any difference in number of lines, but I usually do this.

Is there a way to add more code?
