Sorry for the newbie questions. I've downloaded built and installed the ethercat master 1.5.2.
Used the generic driver to communicated with an Beckhoff EK1101 hub, EL1034 digital input and EL2034 digital output. I then modified the ./example/user/main.c code to work with these modules. Seems to work OK. I then looped the digital out to a digital in to some basic performance testing. At a update rate of 1kHz (1 millisecond), it can detect a change on average of about 2 ms. I increased the rate to 2kHz, it can detect a change on average of 1ms, BUT, I see an occasional, "EtherCAT WARNING: Datagram da69fecc (domain0-0-main) was SKIPPED 1 time". I don't see this warning at a 1kHz update rate. Are these reasonable results, and does this imply that the fastest rate I can expect without errors/warnings is 1 kHz? Would I get significantly better results using the Ethercat kernel module for my chipset?
