Apply Start Values From Data Record Ds 143 Immediately - Siemens Simatic ET 200SP Manual

Energy counters
7.2 Preset and apply start values for energy and overflow counters
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 127: Start values for the individual energy meters
The start values for energy meters 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.
Byte 128 ... Byte 157: Initial values for overflow counters
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.
7.2.2

Apply start values from data record DS 143 immediately

It is possible to apply the start values for energy counters and overflow counters for each
individual phase separately by active, reactive and apparent energy.
Requirement
In your STEP 7 project you have created a PLC data type that has an identical structure to
data record DS 143 and you have entered the start values.
