Product introduction

CMC-DCS-6000 Marine discrete control system is a platform hardware equipment for the navigation of the central ship for large-scale ship monitoring and application. This product is equipped with high performance master control module. full system scanning period is low to 10ms. and in two scanning cycles, the heat preparation is complete. and the sequence event recording function of the 1ms time resolution can be realized. Through the flexible configuration of the board, it can realize AI, AO, DI, DO, RTD, TC, SOE and other conventional hard wire interfaces, and support Modbus TCP/RTU, CAN Open, NMEA 0183 and custom protocol communication. This product supports the rapid configuration development of IEC61131-3 standard language, and provides common graphics and functional logic modules based on ship application scenarios, which can realize the rapid configuration development of interfaces and functions.

Product function

• Full redundancy: The system network, control network, controller, communication modules, I/O modules, and power interface modules can be configured in redundancy mode. Chassis level redundancy is supported. Any single point of failure does not affect system functions.
• Multiple isolation: The system power supply is isolated from the onsite power supply, and the module channel is electrically isolated from the system.
• Safety design concept: borrow a lot of safety system design concepts, such as signal quality bit judgment, fault oriented safety, improve system safety;
• Reliability design concept: Meet derating design requirements, and then effectively improve system reliability through FMECA, reliability growth experiment and other measures.
• High performance: 50M high-speed internal Profibus-DP bus, up to 800Mhz main control CPU;
• High-precision timing: Support network timing and double-channel second pulse input, timing accuracy up to us level;
• Strong compatibility: Based on industrial Ethernet and Profibus-DP fieldbus architecture, compatible with Modbus-RTU, Modbus-TCP and other fieldbus protocols, supporting star, ring or bus topology;
• Friendly man-machine interface: feature-rich HMI man-machine interface, in line with IEC61131-3 control algorithm programming software, support user-defined all kinds of function blocks and scripting language;
• Online upgrade: Firmware can be upgraded remotely, hardware configuration and control algorithm can be modified flexibly, and on-site no-stop and no-disturb installation is supported.
• Openness: Supports flexible access to or access to third-party devices through the communication module.
• Rich diagnosis: all modules are equipped with intelligent diagnosis unit, which can directly or indirectly complete self-diagnosis of power supply, communication status, module working status, signal break/short circuit/underrange/overrange, etc., which can provide complete system status diagnosis information and support real-time fault reporting;
• Easy to use: Supports cabinet installation, wall hanging installation, small size, light weight, front cable, easy maintenance.
