Hello

I bought a CNC lathe (ERNAULT sumoa transnum with CNC GE Mark Century 1050 HL) in France, but I have some problems with it.

First: I can execute commands from EXECUTE mode but I can not write instruction in PROGRAM mode, I think it is a protection against editing part program. in the blue book and on the ladder diagram Schematics, I found a device number 510 "PART PROGRAM CUSTOMER EDINH.IX INHIBIT EDIT: internal supervisor devices controlled by the customer machine interface logic. has one state-of-this device Prevents Any exchange to Stored by the program in the control memory ", I tested this device mode interface and its value is 1.

secondly: today by booting the machine I got the attached message on the photo.

if someone can help me I would appreciate it.

cordially
