It features a 10 MB program memory, 16 MB flash memory, and supports up to 23,808 local I\/O points across 31 bases and 372 slots, delivering high-speed execution for complex batch and continuous industrial processes.\u003c\/p\u003e\n\u003ch3\u003eProgram Execution and Instruction Processing\u003c\/h3\u003e\n\u003cp\u003eThe CPU executes basic LD instructions at 0.042 us per step and MOV instructions at 0.126 us per step. For floating-point math, single-precision addition\/subtraction completes in 0.602 us, multiplication in 1.106 us, and division in 1.134 us, while double-precision operations require 1.078 us, 2.394 us, and 2.66 us respectively.\u003c\/p\u003e\n\u003cp\u003eProgram control methods include cyclic scanning, time-driven interrupts, and internal memory interrupts. I\/O refresh supports both scan-synchronous batch processing and immediate direct instruction execution. Programming supports Ladder Diagram (LD), Sequential Function Chart (SFC), Structured Text (ST), and Instruction List (IL) in view-only mode.\u003c\/p\u003e\n\u003ch3\u003eMemory Allocation and System Capacity\u003c\/h3\u003e\n\u003cp\u003eSystem memory includes 512 KB of symbolic variable memory (up to 256 KB retain settable) and 256 KB of direct variable memory (%MW0 to %MW131071 with up to 128 KB retain settable). Additional fixed memory space includes 128 KB for file registers (%RW), 16 KB for input image tables (%IW), 16 KB for output image tables (%QW), and dedicated system flags for PID loop processing, high-speed links, and P2P communications.\u003c\/p\u003e\n\u003cp\u003eThe module manages up to 128,000 network or remote I\/O points using Smart I\/O modules. Maximum rack extension distances reach 100 m using UTP copper cabling and up to 2 km with fiber-optic links.\u003c\/p\u003e\n\u003ch3\u003eCommunication and Hardware Interfaces\u003c\/h3\u003e\n\u003cp\u003eThe CPU features built-in communication interfaces, including one RS-232C serial port supporting Modbus slave protocol and one USB port (12 Mbps) for programming and configuration. Additional network connectivity can be expanded using rack-mounted serial or Ethernet modules.\u003c\/p\u003e\n\u003cp\u003eOperating on a 960 mA backplane current draw, the processor performs comprehensive self-diagnostics including watchdog timing, memory verification, I\/O monitoring, battery status, and power sags. In failover conditions, switchover time completes in less than 50 ms.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e2MLR-CPUH\/F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eMasterLogic-200\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRedundancy\u003c\/td\u003e\n\u003ctd\u003eNon-redundant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProgram Memory\u003c\/td\u003e\n\u003ctd\u003e10 MB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlash Memory\u003c\/td\u003e\n\u003ctd\u003e16 MB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBasic LD Execution Speed\u003c\/td\u003e\n\u003ctd\u003e0.042 us \/ step\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMOV Execution Speed\u003c\/td\u003e\n\u003ctd\u003e0.126 us \/ step\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFloating-Point Math Speed (Single)\u003c\/td\u003e\n\u003ctd\u003e(+\/-) 0.602 us, (*) 1.106 us, (\/) 1.134 us\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFloating-Point Math Speed (Double)\u003c\/td\u003e\n\u003ctd\u003e(+\/-) 1.078 us, (*) 2.394 us, (\/) 2.66 us\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Base Expansion\u003c\/td\u003e\n\u003ctd\u003e31 bases, 372 slots\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Local I\/O Points\u003c\/td\u003e\n\u003ctd\u003e23,808 points (using 64-channel DI\/DO modules)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Remote Network I\/O\u003c\/td\u003e\n\u003ctd\u003e128,000 points (using Smart I\/O)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExtension Distance\u003c\/td\u003e\n\u003ctd\u003e100 m (UTP), 2 km (Fiber-optic)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSymbolic Variable Memory\u003c\/td\u003e\n\u003ctd\u003e512 KB (max 256 KB retain settable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDirect Variable Memory\u003c\/td\u003e\n\u003ctd\u003e256 KB (max 128 KB retain settable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBuilt-in Communication Ports\u003c\/td\u003e\n\u003ctd\u003e1 x RS-232C (Modbus slave), 1 x USB (12 Mbps)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCPU Operation Modes\u003c\/td\u003e\n\u003ctd\u003eRUN, STOP, DEBUG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCPU Restart Modes\u003c\/td\u003e\n\u003ctd\u003eCold, Warm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSwitchover Time\u003c\/td\u003e\n\u003ctd\u003eLess than 50 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003e960 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.12 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum local I\/O capacity supported by the 2MLR-CPUH\/F CPU module?\u003c\/p\u003e\n\u003cp\u003eA: It supports up to 23,808 local I\/O points when using 64-channel discrete I\/O modules distributed across up to 31 expansion bases and 372 slots.\u003c\/p\u003e\n\u003cp\u003eQ: Which communication protocols and interfaces are built directly into the module?\u003c\/p\u003e\n\u003cp\u003eA: The CPU includes a 12 Mbps USB port for configuration and an RS-232C port that natively supports Modbus slave protocol.\u003c\/p\u003e\n\u003cp\u003eQ: How does the module handle retain data during a power failure?\u003c\/p\u003e\n\u003cp\u003eA: Retain data regions for symbolic and direct variable memory are retained based on parameter configuration using battery-backed basic setup parameters.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":67956636385576,"sku":"2MLR-CPUH\/F","price":315.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0827\/6266\/2184\/files\/2MLR-CPUHF1_Cocoai.png?v=1792658763","url":"https:\/\/www.powerdcs.com\/products\/honeywell-2mlr-cpuh-f-masterlogic-cpu-module","provider":"Power DCS Parts Limited","version":"1.0","type":"link"}
