Great points; and thank you for the clarification on delay vs. period. I will want to think through (again) the various needs and values that should be restricted or limited. Say, set a delay of 600s to let the realization sink in after sending a downlink with a 60000m (field trip) vs. 60000ms delay. Of course, I could predetermine the maximum value and simply validate, or simply make each port a separate configuration, and have one port where I can set the values. And to reduce downlink size, if I used the bitmap or other single byte, that would also be helpful to the network. Thank you.
