The high and low limit settings provides limits for the high-high-, high, normal,
low and low-low ranges of the measured value. The actual range of the measured
value is shown on the range output of MVGAPC function block. When a Measured
value expander block (RANGE_XP) is connected to the range output, the logical
outputs of the RANGE_XP are changed accordingly.

GUID-CAE4B020-7131-49BF-BA29-3EEE0EFEA2B8 v2
The GOOSE data must be received at function blocks. There are different GOOSE
receiving function blocks depending on the type of the received data. Refer to the
Engineering manual for more information about how to configure GOOSE.
Function block type Data Type
GOOSEBINRCV 16 single point
GOOSEINTLKRCV 2 single points
16 double points
GOOSEDPRCV Double point
GOOSEINTRCV Integer
GOOSEMVRCV Analog value
GOOSESPRCV Single point
GOOSEXLNRCV Switch status

The GOOSE receive function blocks are used to receive subscribed data from the
GOOSE protocol. The validity of the data value is exposed as outputs of the
function block as well as the validity of the communication. It is recommended to
use these outputs to ensure that only valid data is handled on the subscriber IED.
An example could be to control the external reservation before operating on a bay.
In the figure below, the GOOSESPRCV is used to receive the status of the bay
reservation. The validity of the received data is used in additional logic to
guarantee that the value has good quality before operation on that bay.
