System Overview
Technical Description
Operator workstation
An operator workstation is a computer that is used for controlling and supervising
the process (it shows pictures and dialogs). It can be integrated into SYS 500 System
Server, or reside in a separate computer that is connected to a base system computer.
A laptop computer can also serve as a workstation. It is then connected to the control
system over a dial-up line. The workstation computer can also be connected to a
local area network (LAN) with a modem.
An operator workstation consists of a computer, an operating system, workstation
programs, HSI (Human System Interface) and printers.The MicroSCADA HSI
consists of a display, keyboard and mouse.
Workstation programs
Workstation programs are a set of programs that are used for process supervision
and control. It enables the use of a MicroSCADA Notification Window, which
shows system messages, and MicroSCADA Monitor Starter. The MicroSCADA
Monitor Starter opens MicroSCADA monitors.
MicroSCADA monitors
A MicroSCADA monitor is used to supervise and control a MicroSCADA
application on screen. It enables interaction between the operator and the base
system computer. The monitor may be of Visual SCIL or X-monitor type.
MicroSCADA monitors are always connected to SYS 500. The pictures and dialogs
displayed on a screen of another computer are always stored in the SYS 500 System
Server. The monitor may run remotely on an operator workstation and office
computer via LAN, or remotely on a portable workstation via a dial-up modem or a
GSM mobile phone connection.
Basic functionalities of SYS 500 System Server, e.g. process communication and
reporting, do not require that MicroSCADA monitors are open. The application runs
without them.

MicroSCADA system description
A MicroSCADA system is a system where MicroSCADA Technology products are
used. It can contain one or more computers that are connected to each other in order
to exchange data or pictures.
There are several ways to build a MicroSCADA system. It might contain one or
several base systems, NET units, operator workstations, process units and peripheral
equipment. Different commonly used system configurations are described here. An
example system overview is shown in Figure 2.3.-1.
The computer that serves as an operator workstation can also be used for
other purposes than as an operator workstation.
