Code:

-- ** Staircase logic with external time object and retriggering on input object Version 3.2 ** --
-- ****************************** Created by Erwin van der Zwart **************************** --
-- ************************************** SET PARAMETERS ************************************ --

-- Set input address
AddressInput = '32/1/20 ' -- 01. 1 bit (boolean)
-- Set output address
AddressOutput = '32/1/21'  -- 01. 1 bit (boolean)

-- Set external time address (optional)
AddressExternalTime = '32/1/22' -- 07. 2 byte unsigned integer

-- Use time left indication
UseTimeLeft = true -- Set to false if no time left indication is used

-- Set feedback adress of time left indication (optional)
AddressTimeLeft = '32/1/23' -- 255 byte string

-- Set time delay (Used when external time is not available)
SetDelay = 120 -- 2 minutes

-- Seconds or Minutes
SetSec = true -- Set to false for Minutes

-- Set factor delay (Multiplies Delay)
SetFac = 1

-- Logic can be turned of by value 0

Hi admin, thanks for your response, I need to include it in the script itself. I have tried your script and it only activates the output if the block is true, but I need if the block is true that it activates and deactivates me at the end of the time.
