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
