For MELDAS 300 PLC

[yepingapple]

Hello,

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 ?

Hi yepingapple,

I am afraid I can't be much of a help, but I got very interested in what you are doing since I also have a Meldas 520AMR control on my 1996 Feeler FV-800.

What do you do with the Meldas 520 systems when you "modify signals"? I would be very intersted to know the whole procedure for that.

I also hope that any Meldas 300 owner chime in soon to help you solve your problem.

I know on the 500 controls you need to transfer the ladder from the ROM cassette to a RAM cassette. Once on the RAM cassette you can make changes through the F0 screens. Once the changes are completed the ladder then needs to be transferred back to the ROM cassette. As far as I know you can only get the cassette's from Mitsubishi.

On the 520AMR control you also need an additional adapter as the cassette connector is different then a standard 500 control.

As far as the 300 control I believe it is a similar precedure only using a board instead of a cassette which you would also need to get from Mitsubishi.
