Assignment of data record DS 143
Byte 0 and Byte 1: Version of the data record
Header information for the version of the data record.
Byte 2 ... Byte 7: Control bytes for energy and overflow counter
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.
Byte 8 ... byte 157: Start values for the individual energy meters and overflow counters
The start values for energy counters in data record 143 are 64-bit floating point numbers.
The format corresponds to the data type LREAL in S7-1200 and in S7-1500.
The initial values for overflow counters in data record 143 are 16-bit integers. The format
corresponds to the data type UINT in S7-1200 and in S7-1500.
Byte 158 ... byte 169: Start values for operating hours counter
The start values for operating hours counters in data record 143 are 32-bit integers. The
format corresponds to the data type REAL in S7-1200 and in S7-1500.
