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.
Example (4-Wire Wye):

In the example, a status query is performed 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.
