I don't know if this has come up before or not, but several times a year we have to do special interfacing between our machines and external devices. Our older machines were able to do onboard ladder edits so I could modify and add inputs to the custom user macros to monitor bits. The new machines have the edit functions locked out so we can not do the edits and the user custom macros #1000 - #1015) are not brought out to external inputs so I need to find a way to edit the ladder once I download it from the machine. I am looking for suggestions if anyone has used a ladder edit program. I know there is Fanuc ladder III but have not priced it yet but don't know if there are any other software packages available. Thanks
