Procedure
Data record 142 is located on the AI Energy Meter 400VAC ST. Use SFB "RDREC" to read
out the data record from the module. This system function block is stored in the STEP 7
library.
Measured values in STEP 7 as of V5.5
Measured values are represented as negative values in STEP 7 as of V5.5 if the value range
of the integer format (32767 dec) is exceeded. This is not an error in the measured value.
Solution: Select hexadecimal representation.
Conversion of 64-bit floating-point numbers
If you cannot process 64-bit floating-point numbers in your automation system, we
recommend conversion to 32-bit floating-point numbers. Note the conversion can cause loss
of accuracy. For a description of the conversion of the 64-bit floating-point numbers (data
type LREAL) into 32-bit floating-point numbers (data type REAL) please refer to the Internet
(http://support.automation.siemens.com/WW/view/en/56600676).
