compactRIO + interbus + servo

[Alex@GT]

I have a servo drive i am attempting to interface with using a compactRIO-9082. However, the drive uses the interbus protocol an an ethernet RJ-45 cable. What would be the best solution to acquire communication?

thanks!

NI does not appear to have any drivers for the interbus communication protocol. Since this appears to be a serial protocol you should be able to make basic serial calls using the NI-VISA driver, but this will likely not be simple.

Thanks for the reply. How would i go about setting up interbus communication in VISA, exactly? 

I think another (more expensive) option would be to get a Profibus module as well as a Profibus/Interbus gateway (http://www.anybus.com/products/products.asp?PID=137&ProdType=Anybus%20X-gateway)

Would this work?

cheers.

Hey Alex, 

Just throwing in my 2cents. It probably is going to be much faster to use profibus than try and setup Interbus from scratch. The node you linked to might work if your Interbus device is a master. There is also a c-series profibus module you could use to talk to the converter.

From what I know of Interbus, the underlying complexity is somewhere between profibus and ethercat and you will have a hard time getting it to work. If you really want to go that route you may consider write a complete driver or create a c-series modules so you can resell it.

Thanks for the input, Jesse_D. Could you elaborate on why the profibus approach would only work if the interbus is a master? I'm fairly sure it's a slave drive, so is there any way around that?

Hi Alex, 

I just looked at the device description for the model you posted. It specifically stated that the adapter behaved as an interbus slave. 

The only way around I know is to find a new adapter.

Yes i also just realized this. There doesn't seem to many, if any, Interbus master adapters available. I'll keep searching though.
