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 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.
