General reset
With module versions with 20 bytes of output data you can reset some measured values and
counter levels.
An edge change of 0 -> 1 at the bit for the general reset has the following effect:
● Counters for energy, operating hours and limits start at "0" again.
● Results of the power quality analysis are deleted.
● Minimum and maximum value calculation starts again with initial values.
For the general reset, set bit 7 in byte 16 of the output user data. (Page 195)
Figure 6-1
Substitute value behavior
The substitute values for input values of the AI Energy Meter HF amount to "0".
