Connecting CNC machines

Not sure if it's the best place for this topic.

In my workshop, I'm trying to network the CNC machines.

There are a total of 4 CNC machines: 1 is using TCP/IP, RJ45 cable, and 3 will be running NetBEUI, BNC RG58 cables.

I'm planning to have them connected through a router on the shop floor (using BNC to RJ45 ethernet converter for the BNC), and then connect the router to a computer in the production office (which will be running XP).

Would something like this work? All I really need is so that I can make backup of programs easily, and have the machines download programs off the computer before run, and delete after run, without the privilege to save anything back (which should be easily configured with the right permissions).

What I'm not sure is whether the 3 CNC machines could talk to the router, since they're on NetBeui, and also connected with a ethernet converter.

Any Advice? Thanks in advance.

You might need to use a network hub instead of a router, but it sounds like it should work.

Possible problem issues;
1. tcp/ip machine can't communicate with the netbeui machines and visa versa.
solution: all should be set to the same protocol
2. BNC to RJ45 and then to router. This can be a problem not ony in the media conversion but your router is not a managed switch. You will need to change/manage the port this bus connects to half duplex/full duplex 10mb. At auto the connection will fail to negociate.

It shouldn't be a problem for me to change that one CNC from TCP/IP to NetBEUI, I think it's on either Win98 or 95.

So basically, have them all on NetBEUI including the computer they will be connected to (the computer that acts as a file server), and get a smart switch instead of a router to manage the connections?

If that's the case, I'll do a test on one of the old CNC machines with NetBEUI first, see if it can talk to the file server with the media conversion in place before running the cables and all those expensive stuff.
