Structure of the control and feedback interface for DS 143

Introduction
Bytes 2 to 7 of data record 143 form the phase-based control and feedback interface for the
measured value data record of the energy counter.
● Bytes 2 and 3: Control and feedback interface for phase 1
● Bytes 4 and 5: Control and feedback interface for phase 2
● Bytes 6 and 7: Control and feedback interface for phase 3
Status information
When data record 143 is read with the RDREC instruction, Bytes 2 to 7 supply phase-
specific status information for energy counters.
The status information enables you can see which counters are returning their values in the
data record 143. If energy counters return their values in the status byte 1, you can
determine the type of energy counter with status byte 2.
