We recently just finished a huge shutdown/turnaround at 2 of our big plants. One plant we went with controlnet over devicenet (CN2DN) again, done this several times now, at the other plant we went with ethernetIP over devicenet (EN2DN). All mcc buckets and other ``dumb`` things are devicenet with DSA/ E3+ drawback the slower baud rate, things like vfd`s servo`s etc are either controlnet or ethernet, higher baud rates. We just recently took another week long course on Industrial Comm. Proticals, including old dh+rio 56.7k "10000ft baudrate and profibus/fieldbus (modicon plc)
Anyways to get to the point, I asked the instructor if we were ever in a bind at 2.00am in the morning and our allen bradley controlnet splice kit was missing or out of connectors, could you use a normal comppression BNC connetor to get by.
Does anyone here know if it will work, and if they do whats the difference between allenbradleys controlnet connectors and normal BNC connectors. I know that the ethernetnet just uses normal RJ45 jacks but ethercat is different and you need the proper terminal ends.
