Description

The Allen-Bradley 1771-DMC is an intelligent control coprocessor module for the 1771 Universal I/O System, designed to execute complex application logic independently of the main PLC processor. Featuring 256 KB of onboard memory, it supports C and BASIC programming, allowing users to perform advanced mathematical calculations, protocol conversion, data logging, and other computationally intensive tasks without affecting PLC scan performance. The module can operate with or without a programmable controller, providing a flexible solution for industrial automation applications.

Functions

Offloads complex calculations from the main PLC processor.

Executes custom applications written in C or BASIC.

Performs protocol conversion between industrial devices and communication networks.

Supports advanced mathematical algorithms and application-specific logic.

Exchanges data with the PLC through a TAG-based shared memory system.

Enables historical data logging, production scheduling, and process monitoring.

Advantage

Compared with conventional PLC processor modules, the Allen-Bradley 1771-DMC provides dedicated computing resources for complex automation tasks, reducing processor loading and improving overall system performance. Its programmable architecture and expandable design make it a versatile solution for specialized industrial applications.

Independent Processing Capability: Executes complex calculations separately from the main PLC, reducing scan time and improving controller efficiency.
Flexible Programming Environment: Supports both C and BASIC programming languages, enabling the development of customized industrial applications.
Advanced Shared Memory Management: Uses a TAG-based communication system for reliable and organized data exchange between the coprocessor and PLC.
Expandable Memory and Communication: Supports optional RAM SIMMs for memory expansion and the 1771-DXPS serial expander for additional communication interfaces.
Protocol Conversion Support: Simplifies integration between PLC systems and third-party devices by performing protocol conversion directly on the coprocessor.
Versatile Application Support: Suitable for advanced process calculations, statistical analysis, data logging, production scheduling, and other computationally intensive tasks.
Seamless 1771 System Integration: Designed specifically for the Allen-Bradley 1771 platform, ensuring reliable compatibility with existing PLC-5 and Universal I/O systems.
