Connect AC800M controller (CI855) to faraway network switch
Could you please help me with this issue:
I have one AC70 connecting to AC450 thru Advant Filedbus 100 (hard wire). That wire is underground with long distance. Now I want to upgrade AC70 with AF100 to AC800M with MB300 (current Control Network of AC450) Interface module CI855.
The issue is there any way to take advantage of existing hard wire to connect AC800M(CI855) to MB300 network switch? I don't have route for Fiber optics.
Thank you in advance.
can't you use AF100 with new AC800M+CI869 in place of AC70? In this case you don't have to worry about whether communication will work or not.
Note that MB300 is not based on TCP/IP, it works via UDP ethernet protocol and it is not easy to find a reliable ethernet switch which works with MB300.
If you really need to use MB300 then *maybe* you can think about using pair of ethernet extenders via RS485.
The first one I have googled is PATTON CL1101/TB.
For me this solution is more curiosity than reliable one. You should definitely test it before you go ahead.
