We are having problems with failures when attempting relatively rapid CANopen write requests. The initial estimate for the system assumed that four 1 Mbit CANbuses would support 80 writes at 50 Hz. In theory it looks easy, looking at bandwidth (assumed 50 bits per frame, gives 50 kbit/s per CANbus).
The question is basic, but probably not easy to answer: is it reasonable to expect to do 20 writes at 50 Hz = 1000 writes per second on each CANbus using CANopen? The web-page
