PDP406 | METSO DISTRIBUTED PROCESSING UNIT

DISTRIBUTED PROCESSING UNITREV A/ACPU PROCESSORThe Model PDP Distributed Processing Unit (DPU), which runs under theWindows CE.net real-time multitasking operating system, is the hardwareprocessing engine of the maxDNA distributed control system. The DPUperforms primary data acquisition, control, and data processing functions.The DPU, also known as maxDPU4F, is a self-contained microprocessorbased, rack-mounted unit, which occupies a single slot in a RemoteProcessing Unit cabinet using an 8-wide maxPAC backplane. It is designedto operate with user-defined combinations of maxDNA Model IOPInput/Output Modules, and to communicate with other devices, such asProgrammable Logic Controllers and Remote Terminal Units.As a station on maxNET, the DPU scans and processes information for useby other devices in the maxDNA system. Each DPU performs:• Comprehensive alarming and calculations.• Logging of Sequence of Events (SOE) data at 1 millisecond resolution.• Acquisition of trend information.• Continuous scanning of Model IOP I/O modules.• Execution of predefined algorithms, called Function Blocks, for processcontrol and data acquisition.
