Hello, I have 1.5.1 EtherCAT Master running on two machines: one is Intel-Atom based with two e1000e network interfaces, the other is a core i7 with an Intel 82579LM Ethernet interface. The operating system is Ubuntu 10.04LTS running the 2.6.33.7.2-rt30 kernel (RT PREEMPT).
A year ago, I was able to get the EtherLAB EtherCAT master up and running on similar computers with frame rates around 2000/sec. However, despite running the same program from a year ago with the same hardware, I can't get the frame rate to exceed 250/sec on either machine. With both the generic and e1000e drivers, the results are exactly the same (which is odd). I saw this in the mailing list archives: [snip] Now as I understand the product to get an update rate of 10 micro seconds for a small number of IO (that's what we have) we need to get the tx frame rate much higher than the standard 250/sec. [/snip] Is the frame rate capped at 250/sec? Is there a setting I need to change, or some configuration I can modify? I suspect there is something easy and stupid I am overlooking, but I'm at a loss. Thanks in advance for any feedback. Thanks Tom
