AC Measured Value Collection (010)
In the output data of the I/O module, the collection is selected via the COL_ID,
and 4 different measured values are selected from this collection via the
MET_IDs. The corresponding measured values are then made available in the
input data. After this, 4 other measured values can be selected, and so on.

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 parameterized threshold value has been
exceeded.
