Looped Execute Statements Are Intermittent

[jrbusch]

Hi,

 

I am using a sequence to update some component parameters on a page. Basically there is a button to toggle the page between showing data from channels 1 to 20 or data from channels 21 to 40.

The button runs this sequence:

 

if(alarmPage == 1)

   alarmPage = 2

   

   for(i=1, i<21, i++)

         

      // Update RIU Names

      execute("component.RIU"+i+"_NAME.strExpression= 'registry.strRIU"+i+"'")

      execute("component.RIU"+i+"_NAME.strVisible = '~registry.L1_RIU"+i+"_Show_hide_RIU'")

         

      // Update Alarm Low/High

      execute("component.RIU"+i+"_LOW.strExpression = 'Var.alarm"+i+"low'")

      execute("component.RIU"+i+"_HI.strExpression = 'Var.alarm"+i+"high'")

         

   endfor

 

else

   alarmPage = 1

   

   for(i=1, i<21, i++)

         

      // Update RIU Names

      execute("component.RIU"+i+"_NAME.strExpression= 'registry.strRIU"+(i+20)+"'")

      execute("component.RIU"+i+"_NAME.strVisible = '~registry.L1_RIU"+(i+20)+"_Show_hide_RIU'")

       

      // Update Alarm Low/High

      execute("component.RIU"+i+"_LOW.strExpression = 'Var.alarm"+(i+20)+"low'")

      execute("component.RIU"+i+"_HI.strExpression = 'Var.alarm"+(i+20)+"high'")

         

   endfor

endif

 

 

I am finding that when I press the toggle button, about half of the time it functions properly, but the other half of the time, some of the parameters are just not updated. This seems completely random and can vary from just one single parameter not updating to 3/4 of them not updating.

It seems like sometimes some of the execute statements are not completing for some reason.

Any ideas?

 

Thanks,

Rob

I'm assuming that's not all the sequence and you have i declared somewhere.

 

Do you get any alerts in the command / alert?  Does it stop half way, or is the update random?  i.e. do components 1-8 update but not 9-20, or is it more random?

Hey Guru,

 

You're right, I was using a global i for some silly reason. I changed it to declare i private within the sequence and problem solved.

 

Thanks!

Yeah, that would do it!  Some other thread must have been changing i at the same time.
