As I know, the fastest wireless update is 4 sec. This may be too slow for capturing position feedback for certain valve application. Will the future transmit rate improved to capture events that happen within this 4 sec ?
Yes, there is a WirelessHART function called Report-by-Exception. It will transmit the feedback position only when there is a change in travel position. It means that data is transmitted only when there is a triggered and includes a timestamp. This will helps to improved battery life.

Currently we have product with 1 sec update rate
