Old Values As New Values

NOAll values from communication (even old ones) go to the system as new values.

...

I/O tag address consists of three parts.

First one defines the type of value:

  • P - Power (calculated from Energy read from the input file)
  • W - Work (calculated by integrating Power within current hour)
  • E - Energy (directly from the input file with possible recalculations due to size of Interval -  see the parameter Expected Interval)

value of Work or Power. The second one - "Primary EAN Code" and "BackupEAN Code" are used as a unique identifier of value, which is placed in "Address Column Name" of source file.

The third part represents the value type (AP+,AP-,AQ+,AQ-), which is in the "Value Type Column Name".
