3. PACiS GATEWAY MANAGEMENT
3.1 Configuration management
The Configuration files are divided into two main parts:
•
SBUS mapping (Station Bus),
•
TBUS mapping (Telecontrol Bus).
The kernel reads the configuration file during the initialisation phase of the PACiS GTW
application. It subscribes to SBUS predefined data, then runs as much Protocol DLL
processes as defined in configuration and product definition (each protocol DLL is under
license).
3.1.1 Configuration tool
To operate the PACiS GTW needs a configuration file or database. It is generated by PACiS
SCE (System Configuration Editor). The generated database has a specific configuration
version incremented when creating or updating the control system.
The database is a zip file that contains all data needed to operate the PACiS GTW. It is to be
noticed that there is no on line settings or parameterisation of the PACiS GTW.
Details of the configuration process are described in the AP chapter.
3.1.2 Downloading tool
PACiS SCE provides a configuration file that has to be downloaded into the PACiS GTW
possibly through SBUS Ethernet network. This operation is done thanks to PACiS SMT
(System Management Tool).
Without database or in case of fault the PACiS GTW remains in a maintenance mode.
PACiS SMT has the following features:
•
to download a stand-by database,
•
to switch stand-by database to operational one,
•
to change by operator request the operating mode between maintenance and
operational.
3.2 Database management
The PACiS GTW has two databases, the current one (operational) and standby one (or
reserved). New database is downloaded over the standby one without interrupting PACiS
GTW normal behaviour.
Starting with a current database, PACiS GTW checks database coherency to its inner needs.
When SBUS communication starts, PACiS GTW checks communication data coherency
between itself and other devices on IEC 61850.
It checks if IEC 61850 servers are present on Ethernet, if their database version and system
revision are the same.
After the database compatibility checking it subscribes on SBUS network data to transmit to
SCADA.
