When pin 4 is ON, it is possible to change the assignment of function codes for expansion instruction. If power is turned ON with pin 4 turned OFF after function code assignments have been changed, the settings will return to the default settings and the information for the expansion instructions that were changed will be lost. Also, if pin 4 is OFF, expansion instruction information will not be transferred from the Memory Cassette.

I have a somewhat similar problem. We have a vacuum furnace with a CQM1H-CPU51. We have no data whatsoever. The NT620C HMI has started to fade and it is impossible to read anymore and we are replacing it with a NS8. We have the managed to get the program on the NT620 onto the NS8 but anyway all that is for another day.

The immediate problem is to get the program from the CQM1H into CX-Programmer. I have connected CX-Programmer to the CQM1H with a serial cable and run TOOLS, PLC BACKUP TOOL, BACKUP FROM PLC and it searches and finds the PLC NewPLC1[CQM1H] and somewhere in the settings it gets the CPU as CPU51. Unfortunately, no other data whatsoever is transferred. The DIP switch settings are 1,2 & 8 Off; 3,4,5,6 & 7 On.

I'd really appreciate if someone can shed some light on this for me.

Jerry.
