GE Information
1.10 Firmware
The D20/D200 software is based on a core set of software modules, collectively referred to as
the base system. The base system is programmed into the D20/D200 on-board flash memory as
firmware. Processing and data acquisition functionality is distributed between the I/O peripheral
processors, which have similar but smaller base systems, and the D20 main processor. The base
system for the D200 is commonly referred to as the CCU base system. For a detailed description,
see section 2.2.3 ,
D20/D200 base systems have the following features:
•
System calls are available for user-generated software
•
D20 peripheral firmware and processes
•
Support of libraries and processes for a wide range of I/O devices
•
Database manager facility (WESDAC Interface Node)
•
Background system diagnostics
•
Comprehensive diagnostic and maintenance facility support (WESMAINT)
1.11 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:
•
SGConfig, a PC-based tool for configuring D20/D200 hardware and software remotely over
a network or locally through the maintenance port.
•
LogicLinx, an IEC 61131-3 compliant soft logic automation tool comprising a executor
running in the D20/D200 firmware and PC-based editor for creating PLC-like programs.
•
WESMAINT is a maintenance facility that resides on the D20 and D200 accessed through a
simple terminal to view collected data and system status and, for some applications, make
changes to the configuration.
•
68K Monitor, an on-board advanced diagnostic tool accessed thorough a terminal interface
and used for troubleshooting, including memory examination, dumping and editing, setting
break points, and CPU usage and process profiling.
