3.7 MSQI

The calculation of the unbalance will be performed only if the device is used for a 3- or 4-wire system with
unbalanced load.
Some of the measured quantities are available for specific systems only (see appendix).

3.8 GGIO1...12

CAM not only provides measurement data and meter standings of the measured power system. It is also able to
be used as an IEC 61850 gateway, to handle information of external devices, which are themself not IEC 61850
capable.
The CAM may be equipped with up to 4 optional I/O modules. Each of these modules may provide three digital
inputs or two analog inputs. Their corresponding information will be mapped to the IEC 61850 interface. To do so,
to each of the inputs an instance of the node GGIO (1...12) is associated:
- Module 1: GGIO1, GGIO2, GGIO3
- Module 2: GGIO4, GGIO5, GGIO6
- Module 3: GGIO7, GGIO8, GGIO9
- Module 4: GGIO10, GGIO11, GGIO12
For the analog input modules GGIO 3, 6, 9 and 12 are not available, because two inputs each are provided only.
Three kind of measurement information of external devices can be mapped:
 GGIO.Ind: State information, e.g. ON/OFF, a self-monitoring signal, an alarm or event
 GGIO.AnIn: Measured quantity information (0/4...20mA), e.g. from a transducer for active power. The measured
quantity is mapped as a scaled value (e.g. 0...1500W), but without unit.
 GGIO.HTWh / HTVArh / LTWh / LTVArh: Energy meter information, by counting kWh / kvarh metering pulses
from an external device. The distinction between high and low tariff pulses is active only, if tariff switching is
configured in the device.
