Previous State

[Frank68]

Create an event script attached to 1/1/2:

Code:

output '1/1/1'
storage_key = 'prev_value'

curr = event.getvalue()
prev = storage.get(storage_key)

if curr ~= prev then
  grp.write(output, prev)
  storage.set(storage_key, curr)
end

Perfect is good , but if I need to initialize the storage  with the current value , neede to create manualy a script to memorize it , is correct ?

Thank's in adavantage
