20.2.3.2 Receiving data
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.

Application
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.

20.3 IEC/UCA 61850-9-2LE communication protocol
20.3.1 Introduction
Every IED can be provided with communication interfaces enabling it to connect to the process
buses in order to get data from analog data acquisition units close to the process (primary
apparatus), commonly known as Merging Units (MU). The protocol used in this case is the
IEC/UCA 61850-9-2LE communication protocol.
The IEC/UCA 61850-9-2LE standard does not specify the quality of the sampled values. Thus, the
accuracy of the current and voltage inputs to the merging unit and the inaccuracy added by the
merging unit must be coordinated with the requirement for the actual type of protection function.
