Information About 1771-DMC

The 1771-DMC is a control coprocessor module designed for Allen-Bradley's PLC-5 programmable controller systems. With 256 Kbytes of memory, this main module functions as an intelligent companion to the CPU, executing custom programs independently to offload processing tasks. It supports high-level languages like C and BASIC as well as assembly language, which makes it suitable for developing custom control logic, protocol converters, or complex calculations. The module includes two communication ports: one 9-pin EIA RS-232C and one 25-pin configurable for RS-232C, RS-423, or RS-485, providing flexible serial connectivity with peripheral devices, operator interfaces, or other control equipment. This robust module enhances the versatility and computational power of PLC-5 systems without requiring additional external processors.

Key Features:

  • 256 KB Coprocessor Memory: Offers expanded memory for executing custom applications written in C, BASIC, or Assembler.
  • Dual Serial Ports: Includes (1) 9-pin RS-232C and (1) 25-pin configurable RS-232C/RS-423/RS-485 port for connecting to external devices.
  • Independent Processing: Runs user-defined tasks parallel to the main PLC CPU, improving system performance and flexibility.
  • Language Support: Enables application development using multiple programming languages to handle complex or specialized functions.
  • Protocol Conversion: Can be programmed to interface with third-party devices using custom or legacy communication protocols.
  • Integration with PLC-5: Seamlessly fits into PLC-5 systems, providing additional computing capacity without disrupting core logic.
  • DIN Slot Mountable: Fits directly into standard Allen-Bradley 1771 I/O chassis alongside other PLC-5 modules.
  • Versatile Communication: Supports point-to-point, multidrop, and peer-to-peer serial network configurations.
  • Enhanced Application Control: Suitable for custom HMI drivers, data logging, machine diagnostics, and algorithm execution.
  • Industrial Grade Reliability: Built to meet Allen-Bradley’s standards for continuous operation in automation environments.

The 1771-DMC boosts the computational power and flexibility of PLC-5 systems by enabling custom, standalone processing functions that support specialized industrial control applications.
