3.2.7.1 Function block
Figure 15: Function block
3.2.7.2 Functionality
The function block represents the IEC61850 GOOSE communication monitoring and
diagnostics in the relay. Function block includes the GOOSE diagnostic counters
that can be accessed via HMI, and
ALARM
output.
ALARM
output indicates if overall GOOSE communication status is good or not.
If
ALARM
output status is “False”, all GOOSE inputs are receiving data within the
timeout limits. If the output is “True”, there is an issue (e.g. timeout or decoding),
with one or more of GOOSE inputs in the relay.
For more information on the GOOSE configuration and monitoring refer to the
IEC61850 engineering manual.
3.2.8 Serial port supervision SERLCCH

Figure 16: Function block
3.2.8.2 Functionality
The serial port supervision function SERLCCH represents one serial communication
port driver. Depending on the hardware configuration, the protection relay can be
equipped with two UART-based serial communication ports. The communication
ports can be both galvanic (RS-485) or one port could be fiber-optic. The protection
relay uses the ports for serial communication protocol links.
Serial communication drivers are identified in the device configuration as COM1
and COM2, which correspond to function blocks SERLCCH1 and SERLCCH2,
respectively. Each COM port driver has its own setting parameters on the HMI under
Configuration > Communication > COMn (n=1,2).
Output
LNKxLIV
is active (TRUE) whenever characters are received on the serial
interface. Output
CHxLIV
is active (TRUE) while complete link frames are received.
Both outputs go to FALSE state after 15 seconds of inactivity on the port.
