The Rosemount 702 Transmitter is capable of detecting momentary discrete
inputs of 10 milliseconds or more in duration, regardless of the wireless
update rate. At each wireless update, the device reports current discrete
input state along with an accumulating count of close-open cycles for each
input channel.
