Module Overview
ABB DTCC901B (order number 61430001-FU) is a high-performance Ethernet communication module designed for industrial automation, specifically for high-speed data exchange between control systems and Ethernet devices. As the core communication component of ABB Advant OCS, Symphony Plus and other series of control systems, its core function is to build a "high-speed data channel" between the controller and the upper monitoring system, third-party Ethernet devices, and remote I/O modules, supporting real-time data transmission and instruction interaction under industrial Ethernet protocol, and providing key technical support for centralized monitoring, decentralized control and information integration of industrial production processes.
This module has the characteristics of multi protocol support, high transmission rate, and strong anti-interference ability. It can flexibly adapt to different industrial Ethernet architectures and is widely used in industries such as power, chemical, water treatment, and rail transit that require high real-time and reliability communication. It effectively solves the interconnection problem of heterogeneous networks in industrial sites and improves the intelligence and integration level of control systems.
Core functions and technological advantages
2.1 Core Functions
-Multi protocol compatible communication: The core supports basic Ethernet protocols such as TCP/IP and UDP, as well as mainstream industrial Ethernet protocols such as Modbus TCP and EtherNet/IP. It can flexibly switch protocol modes through software configuration, achieving seamless integration with Ethernet devices from different manufacturers without the need for additional protocol conversion modules.
-High speed data transmission: Equipped with a 10/100Mbps adaptive Ethernet interface, supporting full duplex/half duplex communication modes, the data transmission rate can reach up to 100Mbps, and a single module can simultaneously handle multiple communication connections (up to 64 concurrent connections), meeting the needs of large-scale data exchange.
-Flexible communication architecture support: Supports dual working modes of client and server, can be configured according to on-site communication needs, and adapts to various communication topologies such as "upper computer controller", "controller controller", "controller remote device", etc.
-Real time communication and data priority management: Built in communication priority scheduling mechanism can set high priority for key control data, ensuring priority transmission of instruction issuance, emergency status feedback and other data, reducing communication delay, and ensuring real-time control process.
-Comprehensive communication diagnosis and monitoring: It has diagnostic functions such as link status monitoring, data transmission error statistics, and connection status tracking. When network interruption, protocol mismatch, data packet loss, and other faults occur, an alarm signal is immediately triggered and diagnostic information is uploaded to the controller, making it easy to quickly locate the problem.
2.2 Technical advantages
-High compatibility and system adaptability: Perfectly compatible with ABB Advant OCS, Symphony Plus and other series of control systems, it can be directly connected to the system backplane bus to achieve high-speed data exchange with controllers and I/O modules; Simultaneously supporting compatible communication with third-party PLC, HMI, SCADA systems (such as WinCC, Intouch), reducing system integration costs.
-Industrial grade reliability design: adopting enhanced electromagnetic compatibility (EMC) design, complying with IEC 61000-6-2/4 industrial anti-interference standard, which can resist electromagnetic radiation, voltage fluctuations and other interferences in industrial sites; The module adopts isolation protection circuit internally to avoid the impact of Ethernet link failure on the control system.
-Redundant communication support: Supports dual Ethernet port redundant configuration. When the main communication port or link fails, it automatically switches to the backup port with a switching time of ≤ 10ms to ensure the continuity of the communication link; Simultaneously supporting redundant communication units with modules of the same model to enhance system communication reliability.
-Convenient configuration and operation: Visual parameter configuration can be achieved through ABB Control Builder or Symphony Plus Engineer software, supporting online modification of communication protocols, IP addresses, port numbers, and other parameters with real-time effectiveness; The module comes with status indicator lights (power, link, communication, fault), which can visually determine the operating status of the device.
