Have someone can tell me how to save MELDAS-300 PLC to the ROM ?
Because I modified some signals, then save in the ROM, but after restarting the machine, it restituted the origenal.
For MELDAS-520, I had modifed 300 machines .It's good.
For MELDAS-300, I know that it can be modifed and updated in site.
Can you tell me how to operate or recommend some manuals for make it valid ?
