What is the structure of the control and feedback interface for
DS 143?
Introduction
Bytes 2 to 7 of data record 143 (Page 232) form the phase-based control and feedback
interface for the data record DS 143.
● 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, overflow counters and operating hours
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.
