Control information
When data record 143 is written with the WRREC instruction, Bytes 2 to 7 are used as
phase-specific control information for energy counters, overflow counters and operating
hours counter. The length of the control information amounts to 2 bytes for each phase:
● In control byte 1 you determine which counter you want to reset and the time at which
counters are reset.
● In Control byte 2 you determine which energy counters and which overflow counters you
want to reset.
