MELSEC A1N-CPU and MEDOC need some help!

Hi,

I didnt thought i would come across an A1N CPU in my life. But now i have and it is as i thought programmed in MEDOC 2.4.

Is it possible to program this CPU with GC IEC DEVLELOPER 7.04.
I need to convert the MEDOC PLC program to Developer..

And im a bit unsure about the programming cable.. its an SC-05N cable?


Help is apriciated.

I am not sure about IEC Developer but in plain GX Developer there are two ways to import a Medoc programme. For most programmes the simple "import from Melsec Medoc format file" will work but on more complex projects it is sometimes necessary to use Medoc to print to a file and then "import from Melsec Medoc format file (printout)". If this is necessary Medoc will run in a dos box on windows at least up to XP (I have not tried it on a later version) and the only problems tend to be with comms. Using the print functions should not be a problem. In the UK the required cable is an SC-09 but this looks the same as your SC-05N so it could be the same thing.

Thanks for info: I managed to convert the progra into IEC GX Dev.. Via Print..
No I need to convert it to Ladder.. hmm.. Cant find GX Converter any where..

With GX Developer (not IEC) you can connect directly to the cpu (with SC09) and upload the program in ladder.
I don't know if IEC can do that too as I don't have it)

Ahh so i can upload program in ladder.. thats new info.. I can try.. I can make it a try.. Would save some time instead of re writing this whole thing

Is GX Developer free these days?

A harware question about A1N CPU... I have a spare CPU... but does A1N need a rack to work? I have a spare CPU and it get power but no CPU in RUN.. cant connect to it.. I suspect that i need the back plane?

GX developer is about £700 - or £800 with SC09 cable.

I would have thought you should be able to communicate with the A1N without the back plane as it has it's own power supply....... but I don't think I have ever done that.

Got it to Work wonderful!!

.. SC-05N cable works with serial to USB converter and A1N CPU..

Thanks for all help
