3. Configuration and Maintenance
Software
The D20/D200 is equipped with a range of maintenance utilities to assist the user in configuring,
testing and monitoring the system:
3.1 SGConfig
SGConfig is a tool, installed on a personal computer, which helps you manage information
associated with your GE Enegy equipment. The primary use of SGConfig is to facilitate the
configuration of D20/D200 hardware and software through the maintenance port on the main
processor and I/O peripheral.
Information is accessed through a hierarchy of windows, as follows:
Project Window
Provides a graphical representation of your project. Each device in the
project is represented by a corresponding icon. Connections between
devices are shown by a series of lines and arrows.
Device Window
When you double-click on a device, the device window is opened in the
main area. The device window will display all of the configurable
applications for the device. The device window has four tabs:
Data Collection Applications
Data Translation Applications
System Point Database Applications
Data Processing Applications
Application Window
Displays the tables for a particular application.
Report Window
Allows you to select and print reports.
3.2 LogicLinx
The LogicLinx application is a powerful tool that allows the user to program PLC-like logic
functions in the D200 environment. LogicLinx consists of an executor, running in the remote
device firmware and an editor, running in a Windows PC environment, which is used to create
the desired programs. LogicLinx is compliant with all five programming languages defined in
the IEC 61131-3 standard.
3.3 WESMAINT
WESMAINT is a maintenance facility that resides on the D20 and D200. It uses a series of
menus and screens displayed on a PC or VT100 terminal to create a simple interface.
WESMAINT presets a window through which field technicians and programmers can look
directly into the equipment to view collected data and system status and, for some applications,
make changes to the configuration.
