Mitsubishi SSCNET

Hello All,
I have a Mitsubishi powered VMC that is need updates.
The Axis drives are MDS-A-SVJ 's and the spindle is MDS-A-SP.
These appear to be controlled via SSCNET. I am not finding much info on this.
It appears to be some type of high speed serial multi drop bus.

Any pointers would be great.
Thanks

Yep, I have looked through all of that.
There just does not seem to be much info on the MDS-A drives in the first place.
They do appear to be SSCNET but it is not clear which version.
It looks like the MDS-A drives are primarily used with the MELDAS controls.
If I need to put new drives into this machine, it is not worth saving.

Going to drag the o'scope and logic analyzer over to the shop this weekend.
I have not seen to many other people asking / searching for this.
Is there anyone else that might be interested in this?
The machine itself is a Mighty Comet.
I get the impression that there might be a fair number of these sitting in back corners of shops.

Would this help?

He says he has a driver for LCNC 2.7 and links to the PCI card he made on eBay

I made contact with www.yurtaev.com early on.
The MDS-A-SVJ drive predates this card.
The response from www.yurtaev.com was pretty much " I doubt it ".

actually i said i'm pretty sure it won't work with MDS drives as the current firmware is SSCNET II only (MR-J2S-B drives)
i have a basic understanding of SSCNET I protocol (MR-J-B, MR-J2- and plan to implement it in the future.
but i haven't seen MDS drives yet and judging by the differences between SSCNET I and II (no similarities at all except the link-level) i can guess it will not be SSCNET-compatible either. but i just bught a MDS-A-SVJ drive on ebay and will have a look at it when it arrive. but it gonna be tough without a woking setup
