2. LOGICAL DIAGRAM
2.1 Internal Automation
PACiS GTW Gateway operates as an IEC 61850 application. The operating modes can be
described as follows:
FAULT
MAINTENANCE OPERATIONAL
INITIALISATION
[Init OK]
and
[Valid current DB]
Power on or Reset
[Init OK]
and
[Current DB not valid]
Stop
or (Switch DB and [DB changed])
or [DB processing failure]
or [Loss of communication and Key "maintenance_if_dcnx_ethernet" = 1]
Run and [valid current DB]
or [Switch DB performed]
XXXX: operator order (from SMT)
[yyyy]: application event/status
mode not visible from the network
Major fault
Switch DB
Switch DB
and
DB unchanged
Key "maintenance_if_dcnx_ethernet" is described in section 2.1 of chapter Maintenance ( GTW/EN MF/C12)
S0137ENb
FIGURE 1: OPERATING MODES OF THE GATEWAY
Modes:
•
INIT: transitory mode not seen from the network, OS starting, Application starting
SBUS starting: Check servers, Subscribe servers with the same database version
PROT DLL starting: starts one protocol DLL by protocol defined in database (if exist
and valid).
•
MAINTENANCE: Database error (coherency, system revision), DLL error.
•
OPERATIONAL: this mode can be qualified as OK or downgraded. Downgraded
corresponds to a the redundant application failure in case of redundant configuration.
Database downloading is possible in Maintenance and Operational.
Application event/status:
•
[Valid Current DB]: the Application owns a Current ApplicationDataBag, which is valid
(correct signature).
•
[DB Changed]: the Stand-by ApplicationDataBag is different from the Current one (this
is known by the Application).
•
[DB Unchanged]: the Stand-by ApplicationDataBag is the same than the Current one
(this is known by the Application).
•
[Switch DB performed]: the new Current ApplicationDataBag has been correctly
processed.
•
[DB processing failure]: the Current ApplicationDataBag processing has failed.
