The status query was also set in the examples given here. In example 1, the status
query is made for phase L1. No bit is set in the status word (Byte 0) and no error
message is present.
In example 2, the status query is made for phase L3. The status word (Byte 0) is at
0x44, an error has occurred at phase L3 (ERROR, ERR_L3). Byte 2 is at 0x40,
i.e., overvoltage at Phase L3, the set threshold has been exceeded.
