      I"m trying to communicate with a Beckhoff BK9000 bus coupler and to reset the watchdog timer I need to send consecutively the values 0xBECF and 0xAFFE to a single register.

      I only want to send this reset command when the watchdog timer elapsed due to some problem....

      I'm not sure if this is possible with Rexygen......

        thanks for your question. If I understand correctly the solution can look like:

        Hope it helps.

        Cheers, Tomas

          Hi Tomas,

          Thanks, this is indeed a working solution. I only needed to slow down the messages to 1 per second, which is still fine.

            glad I could help. You are right, I didn't take to count the timing. Good luck with your project!

            Cheers, Tomas
