Measured value data records
E.2 Measured value data record for base measurements (DS 142)
Analog input module AI Energy Meter 480VAC/CT HF (6ES7134-6PA00-0CU0)
Manual, 07/2018, A5E42674880-AA
229
Procedure
Data record 142 is located on the AI Energy Meter HF. Use the RDREC instruction to read
out the data record from the module. This system function block is stored in the STEP 7
library.
E.2.2
Measured value data record for basic measured values (DS 142) version 3
Measured variables of the module
The following table provides an overview of all the measured variables that data record 142
supplies. Please note that, depending on the connection type used the display of some
measured variables does not make sense and that the module deletes measured values that
are not relevant.
The measured value identification (measured value ID) is an index which references the
overview table of the measured variables in appendix (Measured variables (Page 163)).
