Operating at a 24 MHz clock frequency, it executes control logic and manages communication across distributed automation architectures. The unit features 16 MB of total RAM, providing 10.337 MB of dedicated memory for user applications, alongside an integrated CompactFlash interface for program and backup storage.\u003c\/p\u003e\n\u003ch3\u003eProcessing Performance and Communication Architecture\u003c\/h3\u003e\n\u003cp\u003eThe processor board delivers an execution speed of 0.46 ms per 1000 Boolean operations to ensure stable loop control and logic processing. The unit incorporates two RJ45 Ethernet ports (CN1 and CN2) for control network connectivity, with each base plate assigned a unique hardware Ethernet address to ensure distinct network identity. Dual RS-232C serial ports handle local access and communication, where COM3 supports modem control functions and COM4 provides an isolated serial channel for engineering tools and system configuration.\u003c\/p\u003e\n\u003ch3\u003eOperational Characteristics and Hardware Features\u003c\/h3\u003e\n\u003cp\u003eThe module operates from a 24 VDC power supply with a typical power consumption of 4.32 W. It supports hot standby CPU redundancy for applications requiring continuous control availability. Status monitored via front-panel LED indicators and a real-time clock assist with diagnostic tracking. Built with an IP20 protection class, the module mounts directly onto standard DIN rails using ABB's slide-and-lock attachment mechanism.\u003c\/p\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\u003ePM856K01\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eABB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e3BSE018104R1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eCPU Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eABB AC 800M, System 800xA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClock Frequency\u003c\/td\u003e\n\u003ctd\u003e24 MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExecution Speed\u003c\/td\u003e\n\u003ctd\u003e0.46 ms per 1000 Boolean operations\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMemory Capacity\u003c\/td\u003e\n\u003ctd\u003e16 MB RAM (10.337 MB available for applications)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage\u003c\/td\u003e\n\u003ctd\u003eIntegrated CompactFlash storage\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interfaces\u003c\/td\u003e\n\u003ctd\u003e2 x RJ45 Ethernet (CN1, CN2), 2 x RS-232C (COM3, COM4)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRedundancy Support\u003c\/td\u003e\n\u003ctd\u003eHot standby redundancy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e4.32 W (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 deg C to +60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-25 deg C to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection Class\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003eDIN rail (slide-and-lock mechanism)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eCE, RoHS, WEEE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eSweden\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 available memory for user applications on the ABB PM856K01?
