SBC Software
Runtime database system (DMS)
The data management system is the central
database of the entire system. All process data is
managed in the DMS and is available at all times.
Communication with the individual program
parts (e.g. the graphic editor) is event-oriented.
Long-term database system (PDBS)
The database system stores and manages
history data, alarms and logs. This module also
allows data to be exported to other databases,
enabling process data to be collected in real
time and stored in different databases.
Process Engineering Tool (PET)
The PET provides a clear and easy display of all data from the data manage-
ment system in table form. All data (incl. communication, alarming, logging,
functions, etc.) belonging to a project can therefore be created and
managed in the process engineering tool.
Database systems
The S-Driver
The S-Driver is used for communication with SBC automation stations based
on the S-Bus protocol. The driver supports all types of communication, e.g.
serial interface, modem, USB and TCP/IP. Because the S-Driver is based on
the SBC proprietary SCOMM-DLL, all PG5 tools can be used in parallel with it.
The S-Driver has a mechanism to optimise data traffic using automatically
generated telegram packets. A further optimisation is achieved by prioritis-
ing telegrams according to categories, such as alarms, actual values, or
setpoints.
Visi.Plus as OPC client
To enable the neutral integration of automation systems even from
other manufacturers, Visi.Plus offers an OPC client that reads data
from the OPC Server of a third-party supplier and automatically
enters it in the Visi.Plus DMS database. The user can then access it
for further processing in the Graphic Editor or Alarm Manager, or
for storage in the historical database.
Communication drivers
BACnet Driver
This driver has been developed completely independent of the system, this
allows the scanning and the preparation of any objects. Optimal integration
is achieved however, with Saia PCD® products.
This driver enables communication between one or several BACnet-capable
devices and the Visi.Plus.
