DS200EXDEG1A Turbine Control System

Functional Overview
The DS200EXDEG1A is a 24-channel discrete (digital) input module in the GE Mark VIe control system. Its primary function is to collect discrete signals (contact open/close signals) generated by field devices such as sensors,
 switches, and relays, convert them into digital signals that can be recognized and processed by the PLC or control system CPU,
and transmit the processed data to the GE Speedtronic turbine control system or other control equipment, enabling automated control and monitoring.

Certifications and Safety

This module is UL certified and can be used in both hazardous and non-hazardous locations. The UL certification covers various classes and divisions, and relevant UL mark documents are available for reference.

The system controller uses a RISC processor chip, and the program adopts a task running mode. Each task can set the running cycle and running priority. Therefore, it can not only meet the control requirements of complex regulating loops (generally requiring a long control period), but also meet the fast electrical switching control requirements, so that one controller can cover the control requirements of all aspects of the factory. A large number of user-defined control function blocks are reserved during programming. Users can add or subtract functions according to future production needs. The application of the IEC61131-3 programming standard allows users to quickly become familiar with it as long as they have some basic knowledge. The system is programmed.

(3) System global database technology

The core technology of the system’s global database is “decentralized storage , global management”. The system programming software only generates a project file for the project. Although each controller opens up a certain space as a data variable storage area, there is only a global system variable table on the system programming software for data exchange between the operator station and the process station. There is no need to convert the database to direct access programming. The modification and inspection of variables are also global to the system. The configuration of the system’s process station and operator station is a set of software. The installation, commissioning and start-up of the automatic control part of the entire project only took two or three weeks, which is a very important factor.

(4) Open TCP/IP protocol

Ethernet technology uses TCP/IP protocol Ethernet modules in the operator station, engineering station and process, so that the system can be connected to the factory LAN without adding additional equipment. Since the system supports standard DDE and OPC data exchange standards, the system can be connected with various Data exchange with third-party databases or software will be easier.

(5) The system is easy to expand

The system software has no resource limit. If the user needs technical transformation in the future, new control points, process stations, and engineering station software do not need to be purchased again. During programming, only a few resources can be added under the original project file project tree, which will facilitate the user’s future system development. expansion and long-term development.

(6) Chinese interface

The system menu, operation panel, system character table and system prompt information are all in Chinese.

4. Characteristics of S800 I/O station

Industrial IT’s I/O modules are all intelligent modules with their own CPUs. Their main functions are signal conditioning and A/D, D/A conversion, and completing various data including linearization and engineering unit conversion. preprocessing.

As a distributed process I/O station, S800 I/O is modular in design, economical, flexible, easy to install and wire, and can be directly connected to the drive system. Its modules and terminal blocks can be combined at will to suit different space and application requirements.
