I am using GX Dev. FX (ver. 5.0). I am trying to delete a line in the program. I have made a copy of the original and given it a rev no. and deleted the appropriate part of the ladder. When I come to convert it, the program assumes that I am connected to the PLC, although I am off-line. Needless to say it returns an error message that there is no communication with the PLC. Can someone advise as to where I am going wrong in not being able to convert a program off-line. Appreciate your advise, thanks.
