System Overview
Technical Description
Integrated and distributed systems
Both the integrated and the distributed systems contain SYS 500 with all its
components. The system components (a communication system and a workstation)
can be optionally integrated to it in an integrated system. The distributed system
contains, in addition to SYS 500, a communication frontend or an operator
workstation.

Single and redundant systems

A single system is a MicroSCADA system that contains only one unit of each
system component, while a redundant system can contain two base systems, and/or
two NET units and/or two LAN connections dedicated for the same purpose. The
idea with a redundant system is to make the system more safe when doubling some
of its components. In most systems, the component availability is very important.
This means that if one of the system components fails, the other one takes over the
specific functions immediately after it has recognised a break-down in the other base
system.
