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

Plenty of information, how helpful it is, i do not know. Some pdf look very promising.

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.

If the machine is currently functional then it is just about plausible that you could monitor and reverse-engineer the protocol.

However, unless you want a project, it might not be sensible to attempt.

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?
