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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e256 KB Coprocessor Memory: Offers expanded memory for executing custom applications written in C, BASIC, or Assembler.\u003c\/li\u003e\n\u003cli\u003eDual 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.\u003c\/li\u003e\n\u003cli\u003eIndependent Processing: Runs user-defined tasks parallel to the main PLC CPU, improving system performance and flexibility.\u003c\/li\u003e\n\u003cli\u003eLanguage Support: Enables application development using multiple programming languages to handle complex or specialized functions.\u003c\/li\u003e\n\u003cli\u003eProtocol Conversion: Can be programmed to interface with third-party devices using custom or legacy communication protocols.\u003c\/li\u003e\n\u003cli\u003eIntegration with PLC-5: Seamlessly fits into PLC-5 systems, providing additional computing capacity without disrupting core logic.\u003c\/li\u003e\n\u003cli\u003eDIN Slot Mountable: Fits directly into standard Allen-Bradley 1771 I\/O chassis alongside other PLC-5 modules.\u003c\/li\u003e\n\u003cli\u003eVersatile Communication: Supports point-to-point, multidrop, and peer-to-peer serial network configurations.\u003c\/li\u003e\n\u003cli\u003eEnhanced Application Control: Suitable for custom HMI drivers, data logging, machine diagnostics, and algorithm execution.\u003c\/li\u003e\n\u003cli\u003eIndustrial Grade Reliability: Built to meet Allen-Bradley’s standards for continuous operation in automation environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 1771-DMC boosts the computational power and flexibility of PLC-5 systems by enabling custom, standalone processing functions that support specialized industrial control applications.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":49105332568320,"sku":"1771-DMC","price":2938.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0388\/5331\/2557\/files\/73449-01-04.jpg?v=1785545080","url":"https:\/\/alotechparts.com\/products\/1771-dmc-allen-bradley-plc-5-control-coprocessor-main-module-256kb","provider":"Alo Tech Solutions","version":"1.0","type":"link"}
