Ändern von geplante Programmzeiten dynamisch durch die Visualisierung

 

Task

How to allow end-user to change time from visualization system (so he doesn’t go into scripting) when the shutters are opened in the morning and when closed in the evening.

Create objects

  • Create 3 objects:
    – Scheduler start time (type: 10. 3 byte time / day)
    – Scheduler end time (type: 10. 3 byte time / day)
    – Control object e.g. shutters (type: 1. 1 bit boolean)

User function library program

Add following code to Scripting -> Tools -> User Function Library:

  1. function matchdate(now, obj)
  2.     -- get object value
  3.     local odate = grp.getvalue(obj)
  4.     -- check hour and minute parts, seconds are ignored
  5.     return type(odate) == 'table' and now.hour == odate.hour and now.min == odate.minute
  6.   end
  7.  
  8.   function scheduler(startobj, endobj, ctrlobj)
  9.     -- current date as table
  10.     local now = os.date('*t')
  11.  
  12.     -- check schedule start
  13.     if matchdate(now, startobj) then
  14.       grp.write(ctrlobj, true, dt.bool)
  15.     end
  16.  
  17.     -- check schedule end
  18.     if matchdate(now, endobj) then
  19.       grp.write(ctrlobj, false, dt.bool)
  20.     end
  21.   end

Scheduled program

Create scheduled script that runs every minute.

  1. scheduler("auto_scheduler_start", "auto_scheduler_stop", "shutters1")

Launching objects from visualization

Day is not checked in this example, only Time value.

More complex logic on event

  • We can create an Event-based script for control of the object which can execute more complex logic for example:
    – Morning: open shutter1 on 50%, shutter2 – 100%
    – Evening: leave shutter1 opened on 10%, shutter2 – fully closed
  1. value = cnv.decode(event.datahex, dt.bool)
  2.   -- scheduler start
  3.   if value then
  4.     grp.write('dimmer 1', 50)
  5.     grp.write('dimmer 2', 100)
  6.   -- scheduler end
  7.   else
  8.     grp.write('dimmer 1', 10)
  9.     grp.write('dimmer 2', 0)
  10.   end
