siggiv Posted February 11, 2015 Share Posted February 11, 2015 Hi I am trying to make a user input to activate alarm according to weekday and time of day. For example make alarm active (enable) from 18:00 on friday evening to 08:00 on monday morning. similar as "Active Times" in DAQConnect. here is how I started: while (1) if ((systime() > 18h) && (systime() <= (08h)) & (v.ON_Button_Alarm[0] == 1)) Alarm.MyAlarm.Enabled = True Else Alarm.MyAlarm.Enabled = False Endif delay(1)endwhile Thanks for any help siggi Link to comment Share on other sites More sharing options...
AzeoTech Posted February 13, 2015 Share Posted February 13, 2015 Its probably easier to simply put the criterea in the alarm itself. I personally would create a function that returns 0 or 1 depending on whether the alarm should be active, then you could use the same criterea for a group of alarms. So if the alarm expression was just: myChannel[0] > 50 you would do something like: (myChannel[0] > 50) && alarmsActive() where alarmsActive() is a function like: function alarmsActive() return(v.On_Button_alarm[0] && (systime() % 86400 > 3600*8) && (systime() % 86400 < 3600 * 18))) I like using % 86400 to determine time of day rather than hms notation. Note that this just disables the alarm if v.On_button_alarm is 0, and the current time of day is between 08:00 and 18:00. Link to comment Share on other sites More sharing options...
