GE 8521-LC-MT Hybrid Controller

GE 8521-LC-MT Hybrid Controller

OVERVIEW

PAC8000 Hybrid Control provides a fully integrated solution for process control, logic automation and strategy development. PAC8000 Hybrid Control provides a process engineer with the tools to design, implement, document, and maintain a process control system using advanced control strategies. PAC8000 Hybrid Control consists of a number of open system components. 

 The PAC8000 Hybrid Workbench is an integrated development environment that centralizes and coordinates project data including instrument indexes, control strategies (process and logic) and project management. It configures the control logic and generates an export database to create the operator (HMI) database.  A rugged field-mountable Control Platform, consisting of the PAC8000 Hybrid controller (8521- HC-MT) and the 8000 Process I/O system.

Applications

PAC8000 Hybrid Control is designed to satisfy the process automation market, which includes industries like: power generation and electrical distribution, food and beverage, chemicals and petrochemicals, water and waste water, oil and gas pipelines, cement and pulp and paper. PAC8000 Hybrid Control, with its simultaneous support of both process and logic automation strategies, is an ideal solution for process applications that may also require some sequential logic control in a process environment.

PAC8000 Process Control

PAC8000 Process Control is an open, easy-to-use process control engineering and management solution that delivers comprehensive, distributed control system functionality. PAC8000 Process Control is a fully integrated advanced process control and instrument engineering system offering configuration tools, modeling, simulation, troubleshooting utilities, project drawing management and self-documentation. It is a robust solution that provides the flexibility to configure control systems ranging from a few loops to thousands of points. A flexible, scalable design allows cost effective system expansion. In addition, the system's extensive use of industry standards simplifies integration with other applications.

PAC8000 Logic Control

The PAC8000 Hybrid Workbench is your complete tool kit for creating IEC 61131-3 programs. The Workbench fully supports the five IEC 61131-3 automation languages - Ladder Diagram (LD), Sequential Function Chart (SFC), Function Block Diagram (FBD), Structured Text (ST), Instruction List (IL) - plus Flow Chart and is used to develop, download, simulate, debug, monitor, and edit application programs. PAC8000 Logic Control lets you mix programming languages in the same project. Its true Windows interface will guide you through development of your project. The Workbench Simulator will test your programs before startup. Then use the Workbench to dynamically view programs as they run in real-time and make changes on-the-fly.

PAC8000 Control Platform

The PAC8000 controller executes your control strategies and manages all control activities for the I/O modules. It also manages communications on the control network. The controller provides a tight control loop response, providing a control output in response to input data within 100 ms. The controller incorporates a rigorous redundancy model, fieldbus integration for connecting to HART® and a Fault Tolerant Ethernet implementation to deliver reliable system operation in your application. The controller can concurrently execute both PAC8000 Process Control strategies for process control and an IEC 61131-3 control language for logic control applications.

PAC8000 Remote I/O

Remote I/O can be used with PAC8000 controllers, allowing you to further distribute control capability in your plant. Connected with an Ethernet Bus Interface Module (EBIM), Remote I/O communicates with the controller using high-speed peer-to-peer communications. The Workbench configures both Remote I/O and local I/O in the same way, providing a fully integrated Remote I/O solution. The PAC8000 Control Platform and Remote I/O are built for harsh process applications, operating over the industrial –40°C to +70°C temperature range that is typically associated with field transmitters and meeting ISA's stringent G3 corrosion resistance requirements. The Controller and I/O solution can both be mounted directly in Division 2 /Zone 2 hazardous areas and, when required, can provide a cost effective intrinsic safety solution.

Redundant PAC8000 Controllers

PAC8000 Hybrid Control offers extensive redundancy choices to provide you with several options to assure that your system provides the required system availability, including: 

 Redundant controllers 

 Control networks 

 System power supplies

Peer to Peer Communications

PAC8000 Controllers can communicate with each other on a peer-to-peer basis, enabling controllers to share data with each other. This capability assures that critical information can be efficiently shared between controllers instead of requiring data to be passed to each controller from the control room.

Benefits Cost saving solution

PAC8000 Hybrid Control takes advantage of Windows 2000 & XP based object-oriented technology, graphical user interfaces and easy to learn software solutions to reduce process control system life cycle expenditures by 30–40%
