5.3 Data registers
These registers are used to store the measured values. They can be read in process data mode [
}
29] , but
not written.
The three sets of registers are loosely assigned to the mains phases, but to some extent also contain
general measured values.

(1)
The status word [
}
42] can be read from any of the three sets of registers. It contains the status
information for all three channels.
(2)
The stored peak current values can be reset to zero at any time using bit 0 of the extended control byte
[
}
30] .
(3)
The energy consumption is stored in the registers every half-hour, and is retained even when the KL8001
is switched off.
(4)
The operating hours are stored every 30 minutes in the register and are retained even if the KL8001 is
switched off.
Reading a data register
If the register number of a data register is entered during process data mode in the associated control byte,
then its contents will be returned in the corresponding process data word.
