Application
SEMOD55872-5 v10
Generic communication function for measured values (MVGAPC) function is used to send the
instantaneous value of an analog signal to other systems or equipment in the substation. It
can also be used inside the same IED, to attach a RANGE aspect to an analog value and to
permit measurement supervision on that value.
Setting guidelines
SEMOD55424-5 v5
The settings available for Generic communication function for Measured Value (MVGAPC)
function allows the user to choose a deadband and a zero deadband for the monitored signal.
Values within the zero deadband are considered as zero.
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.

Receiving data
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.

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.
