Hi All,

very new to Ignition. Im trying to change UDT type parameter via Gateway script that is executed every second\>

system.tag.writeAsync("[default]_types_/GW\_ACV/Parameters.Reset", [1])

it doesn’t seem to do anything, Ive also tried tagConfigure with no success.

What am I missing ?

Parameters are not "live" the same way as tags, so do not propagate the same way. Use `system.tag.configure()` to alter a tag's configuration in a way that will restart the tag.
