Tag triggered script but only on value change - Ceros2112 - 09.06.2026

Hello,

is it possible to trigger an event script based on tag objects but only if the value of that single object is changed?

for example, I have some objects with cyclic send and I want to trigger the script only when the value change

thank you

Use this:

Code:
key = 'prev_value_' .. event.dstraw

value = event.getvalue()

prev = storage.get(key)

if value == prev then

  return

end

storage.set(key, value)

-- put script here
