zenon logic block VACO misses the first value change in each interval

Summary

 
Summary

relative values calculated by the metering point administration may be incorrect under certain conditions

 
 
Description

The relative value that is computed by the metering point administration (or to be more precise by the VACO block in the zenon logic program) is reset to 0 after every archive cycle. If the absolute value changes at the exact same time when the relative value is to be reset to 0, this increase will not be recognized and therefor the calculated relative value is incorrect.

 

 
 
Solution

The described issues has been resolved. Now every value change of the absolute variable is correctly considered, even if the change happens in the exact same moment when the relative value is to be reset.
