7.5 What is the structure of the control and feedback interface for DS 143?
Analog input module AI Energy Meter 480VAC/CT HF (6ES7134-6PA00-0CU0)
68 Manual, 07/2018, A5E42674880-AA
When data record 143 is written with the WRREC instruction, Bytes 2 to 7 are used as
phase-specific control information for energy meters, overflow counters and operating hours
counters. The length of the control information amounts to 2 bytes for each phase:
● In control byte 1 you determine which counter you want to preset and the time at which
counters are to be preset.
