Do you have problem? do you need help? or you just want to share your project?

It is very easy to replace MMC100.2 by MMC103. the only thing you need to do --may PLC USER alarm text, you need read it out and convert to MMC 103 format.

 1st of all, 840D NCU (PLC inside ) can run cutting program without any MMC (no MMC100.2, no MMC103--it can working) --I know some cheap machine builder did like this. Don't worry about to they can run--I am sure they can

All NC software (system and user program are stored in NCU RAM back up by battery during power off.

I suggest you order a used MMC103 (should be in working condition ) just hook up to your 840D NCU, --it is not plugged and play but only a couple of setting need to do 

You need to send a picture of your old OP031? from the back, I need to see you may need to order a power supply for MMC103

PS: if you are in Germany ( i see you wrote German) that should be easy to find old MMC103

if you cannot sure, PM me, I can give you some help

Hi, i am really happy to read an answer from you.. as i see in the other topics you are a pro for this questions :)

I know my english is not the best but i try my best :)

Auf deutsch wäre es einfacher :)

I am sure that i need help!

My biggest problem is, that i dont understand which different it is between the mmc100.2 and the 102/103.

Ok sure the first different is, that my 100.2 works under DOS and my 103 under WIN98 the 103 have a HDD the MMC100.2 not.

My problem is, that the HDD from the bouth 103 was broken and at this time i have buyed a new HDD with 20GB and i only have installed the win98 OS.

What i dont understand is... the mmc100.2 is running under DOS, but where is the 840D Siemens Software installed? On the MMC100.2? Or do i only connect the MMC100.2 to the NCU via MPI and the Software is on the NCU/PLC?

If yes, how can i connect my "new" MMC103 with the NCU/PLC?

If you or someon can and will help me i will be really happy :)

 NCU have "6" is good, but the detail LED , I need to see pictures taking from CNC

You cannot install software to your MMC103.--MMC103 and 840D all discontinued

(PM me how much you bought this MMC103.). your Power supply is good--don't buy another 

You don't answer where you are--Germany?.

My suggestion is the best for you (cost and safety)--"buy a good functional MMC103" from eBay.

You may think to keep your current MMC103 --yes it is possible, but for you may be hard job--you need to find from some other people's machine, the same MMC103, Image his HDD (Ghost or other )--then release to your HDD. do you think it is possible for you. Also, Not every people can do good image-making MMC103 working. 

so search in eBay find the same parts number MMC103 make ask seller if it working send cost link to me. 

I have 2 working MMC103, I can exchange for you.--send you windows only MMC to me, I send working Siemens MMC103 to you--of course,it is not free. PM me for how to exchange for detail

Hi,

i will take a picture today.

The Powersupply is connected to my MMC103 and the MMC103 is booting into Windows.

The MPI cable is connected.

The NCU is booting (showing 6 on the 7-segment)

I need to know what i have to install on the MMC103 to connect the mmc with the NCU.

On the MMC is only installed Windows.

Thank you
