Navigation pane The left pane of the project window displays the names and symbols of all containers
of a project in the form of a folder tree.
Object Each element of a project structure is called an object in DIGSI.
Object properties Each object has properties. These might be general properties that are common to
several objects. An object can also have specific properties.
Off-line In Off-line mode a link with the SIPROTEC 4 device is not necessary. You work with
data which are stored in files.
OI_F Output indication fleeting → Transient information
On-line When working in On-line mode, there is a physical link to a SIPROTEC 4 device which
can be implemented in various ways. This link can be implemented as a direct con-
nection, as a modem connection or as a PROFIBUS FMS connection.
OUT Output indication
Parameter set The parameter set is the set of all parameters that can be set for a SIPROTEC 4
device.
Phone book User addresses for a modem connection are saved in this object type.
PMV Pulse metered value
Process bus Devices with a process bus interface allow direct communication with SICAM HV mod-
ules. The process bus interface is equipped with an Ethernet module.
PROFIBUS PROcess FIeld BUS, the German process and field bus standard, as specified in the
standard EN 50170, Volume 2, PROFIBUS. It defines the functional, electrical, and
mechanical properties for a bit-serial field bus.
PROFIBUS address Within a PROFIBUS network a unique PROFIBUS address has to be assigned to
each SIPROTEC 4 device. A total of 254 PROFIBUS addresses are available for each
PROFIBUS network.
Project Content-wise, a project is the image of a real power supply system. Graphically, a
project is represented by a number of objects which are integrated in a hierarchical
structure. Physically, a project consists of a series of folders and files containing
project data.
Protection devices All devices with a protective function and no control display.
Reorganizing Frequent addition and deletion of objects gives rise to memory areas that can no
longer be used. By cleaning up projects, you can release these memory areas again.
However, a clean up also reassigns the VD addresses. The consequence of that is
that all SIPROTEC 4 devices have to be reinitialised.
