Is there a standard in NMEA 2000 for chartplotters for the update interval? I am sending pressure, humidity and temperature on a five second interval which seems to always show the last updated value. Never

. On the other hand, I have freshwater level sending at at 100ms and sometimes ithe plotter stops displaying and shows

for a period of about one or two minutes, then displays the value again. Same with engine parameters when at a 500ms interval, showing

and then the value about every 10 seconds on and 10 seconds off. Is there a way to know how often to send an update so that the plotter only shows

when Signalk no longer is getting updates from the sensor? I can probably write some logic to ensure there is exactly the interval needed but I would need to start with how often.
