Benchmark Ethernet/IP on LinuxRT

[CyGa]

Hi,

I'd like to connect a PXI controller running LinuxRT with an AllenBradley PLC through EthernetIP.

This setup will replace an existing system that reached its end of life. The PLC system will stay.

The actual PLC code has a loop running at 5ms. And the RPI is set 1 for the EthernetIP communication.

I need to ensure that I'll be able to serve the PLC through that link from the PXI controller. The number of words exchanged is quite small (25 in, 25 out) but still the loop is fast.

Is there a benchmark somewhere (or from experience)  that would highlight the speed that can be reached for Ethernet/IP transactions in that conditions ?
