CORE BUSINESS Distributed Processing Unit (DPU) is the core component of the process control station, used to store system information and process control strategies and data  DPU wiring The connecting wires at the rear of the DPU mainly include power wires, ground wires, dual-machine switching cables, network communication cables, I/O network cables, etc. DPU function expansion OC4000 has the ability to be applied to various control and information processing occasions. According to different applications, DPU can be connected to different I/O systems Features of DPU High-performance 32-bit microprocessor. Single DPU configuration or 1:1 redundant configuration DPU can be used. Redundant DPU can realize bumpless switching in one cycle. DPU system performance Use Windows CE.NET real-time multitasking operating system as the software platform, install OC4000 controller software Network interface card 369B1724P0005 (C9220002) The network interface card is the communication interface between the DPU and the I/O station, and is responsible for the exchange of real-time data between the I/O station and the DPU Composition of DPU Dual machine switching card 369B1861P0006（C2908412A） The dual switch card is an intelligent PC interface card. The dual switch card of the redundant DPU is connected by a cable, which mainly realizes the logical switch of the redundant DPU. Bus backplane The bus backplane is an ISA passive PC bus backplane. There are 6 ISA bus slots on the ISA backplane with power indication. This picture is the appearance of the ISA bus backplane. |
