I’m trying to find the procedure for backing up a Mitsubishi Meldas 320M control, as I won’t have a ton of time to play around and try to figure it out.
Also, what battery does the 320M need?
Here’s a procedure for an M50, but he’s not sure if it’s the same as the 320M:
“Not 100% sure on the M320. On the M50, press DIAG IN/OUT, then press MENU soft key twice, then press OUTPUT. You see a screen showing the various options.
May as well output everything. Type #1 in "#" column and for the DATA column enter "ALL" and press input (it will output over RS-232). Type #2 (for tool data) in # field and leave DATA field blank and hit input again. Then enter #3 (parameters) and nothing in DATA and hit input. Then #5 (common variables), nothing in DATA and hit input. Then type 30 in the # field, nothing in DATA and hit input (outputs macro programs). It should show it as it outputs and say "DATA OUT COMPLETE" when done.
Then hit E-stop, and go to the NC controller in the back of the cabinet and turn the CS2 swith (small rotary switch, usually under a cover plate) to position 1. This stops the ladder. Then type 99 in the # field and "ALL1" in the DATA field, and press INPUT. Then put 99 in the # field and "ALL2" in the DATA field and hit input. Then 99 again in the # field and "ALL3" in the DATA field and input. Turn the CS2 switch back to 0 to re-start the ladder and dis-engage E-stop, machine will be back up and running.
ALL1 is parameters, PLC constants, timers, work offsets, R-registers, PLC latches and switches, spindle and axis parameters, communication settings and all the critical stuff you need.
ALL2 is tool offsets, common variables, too life data, etc.
