I managed to get into the PLC program it was a matter of changing the attributes to -mx which allows the program to be read and modified. The other main issue is the software does not give the full conversational programming which most of these controls have. I have seen a video on YouTube which shows how the software can be updated or changed but there is no clue as to how this software is obtained. I have emailed Fagor Automation but there is no reply as yet. Maybe it is a matter of unlocking different features or changing the license code. I wonder if anybody out there could shed some light on how this is done. Thanks for any replies. Dave.
