System Error Announcement - ABB SAM600 Operation Manual

Section 2
SAM600 Process Bus I/O System
Board temperature: The board temperature of the SAM600 modules is supervised. In case a
board temperature of 80°C or above is detected, a high-temperature alarm is reported. If the
SAM600 module detects board temperature below 80°C, the SAM600 module returns back to
normal operating state.
Board Calibration: SAM600-CT and SAM600-VT modules check at startup the integrity of A/D
calibration. If the check fails a log is created and the condition is reflected in a corresponding
status LED (see Section 7.2.3). In addition, the quality information of the IEC/UCA 61850-9-2LE
stream will indicate this by raising the failure bit (see
Digital input voltage detection: If the SAM600 module fails to detect the input voltage on its
digital input channels, it reports a hardware error.
Sample synchronization status: If the expected synchronization is not achieved (for example,
Grandmaster clock with GPS configured and no time master with GPS connection available),
the SAM600 module reports a mismatch in its synchronization state.
Input stream missing: If the SAM600 module does not detect a stream which the module is
configured to receive on the SAM600 system bus, a stream missing condition is reported.
Note that Input stream supervision is limited to IEC/UCA 61850-9-2LE streams generated by
the SAM600 modules in the system. Bridged-trough streams are not supervised.
Link state of network interfaces: The link state (link up/link down) of all network ports is
constantly monitored. The detected link state is reflected in a corresponding status LED (see
Section 7.2.3). Upon detecting a change in the link state of a port a log entry is recorded.
SAM600 system bus link supervision: In addition to link up/link down supervision of physical
ports the connection of the SAM600 module to the SAM600 system bus is constantly
monitored. In case the SAM600 system bus is configured as HSR ring, a single link failure in the
ring is logged and indicated by the neighboring modules. A double link failure in the HSR ring
(or a single link failure in a daisy chain SAM600 system bus) will be indicated by all modules in
the SAM600 system.
IEEE 1588 time synchronization on network interface: Each SAM600 module constantly
monitors the exchange of IEEE 1588 time synchronization messages with its device neighbors
on the SAM600 system bus and also, if configured, on its uplink port. If a message loss is
detected, the SAM600 module reports this condition as Peer Delay Error and records a log
accordingly.
Mismatch of neighboring SAM600 module: Each SAM600 module constantly monitors the
communication with its device neighbors on the SAM600 system bus. In each of the following
situations the SAM600 module reports a topology error:
• No neighbor is detected on a SAM600 system bus port that should connect to a
neighboring SAM600 module.
• A neighboring SAM600 module is detected, but its SAM600 module identifier or type is
not matching with the system configuration. A neighboring SAM600 module is detected
on a port, but according to the system configuration no SAM600 module should be
connected.
A topology error is indicated by steady light on the HMI (see Section 7.2.3). In addition, a log is
recorded.
