Step7 S7317 problem with a temp varibale

[spook]

Hello,

I met last week a problem with a temp variable in a FC. I changed the program since but i want to understand because other FC/FB uses temp variable.

In the same rung i write then load a tempreal value, and get different values, when i read values online.

      L     "DBWaterAir".SetPoint_LevelTeepolTank    80.0
      L     5.000000e+000                5.00
      -R    
      T     "TempReal"                    75.00

      U(    
      O     "DBWaterAir".TeepolRequest
      O(    
      L     "DBWaterAir".LevelTeepolTank_Pourcent    
      L     #TempReal                    26664 (something like this)
      <=R   
      )     
      )     
      U(    
      L     "DBWaterAir".LevelTeepolTank_Pourcent
      L     "DBWaterAir".SetPoint_LevelTeepolTank
      <R    
      )     
      =     "DBWaterAir".TeepolRequest

This temp real was used in an other rung in the same way, but it was ok. When i changed in the second rung the name of the tempreal, in the first rung, the load value wasn't the same??? then i had to change very fast the programm and delete the first tempreal value.

I don't use any L datas, and all temps (3) are real and transferd with real.

If anyone has an idea
Thanks

Maybe someone can understand what you write, but I cannot.
Also, is the code you have listed the "bad" code or the "good" code ?

If the listing is the complete code, then you are loading a temporary variable (#TempReal) without initialising it. That wont work.

 

[L D[AR2P#0.0]]

I read this as a mix up between

"TempReal" and #TempReal

Tx, it was actually this problem between local and memento variable.
Shame on me

Sorry for my bad english
