ABB DAPI100 3AST000929R109 Ethernet Communication Interface Module

ABB DAPI100 3AST000929R109 Ethernet Communication Interface Module

Product Overview

ABB DAPI100 (order number: 3AST000929R109) is a high-performance Ethernet communication interface module for industrial automation control systems, belonging to the core adapter series of ABB's industrial communication product family. Its core positioning is to serve as a "data bridge" between industrial equipment and Ethernet networks, enabling bidirectional data exchange between industrial equipment such as PLCs, controllers, I/O modules, intelligent instruments, and upper monitoring systems (SCADA/HMI), enterprise management systems (MES/ERP), and cloud platforms through standardized Ethernet protocols. It solves communication compatibility issues between different devices in industrial sites and is a key component in building transparent and efficient industrial communication networks.

This module integrates ABB's technological advantages in industrial communication protocol parsing and anti-interference design, with features such as high communication speed, strong protocol compatibility, good stability, and outstanding anti-interference ability. It can adapt to the complex electromagnetic environment and harsh operating conditions of industrial sites such as metallurgy, chemical, power, and automotive manufacturing. Its modular design supports quick installation and flexible configuration, and can be seamlessly integrated into mainstream control systems such as ABB AC 800M and Symphony Plus. It is also compatible with third-party industrial equipment, greatly reducing the difficulty of system communication integration.

Core functions and roles

2.1 Multi protocol data conversion and forwarding

The DAPI100 module has powerful protocol conversion capabilities and can achieve bidirectional conversion between industrial equipment specific protocols and standard Ethernet protocols. The module is equipped with various mainstream industrial communication protocol parsing engines, including PROFIBUS DP, Modbus RTU/TCP, EtherNet/IP, ABB dedicated PPA bus protocol, etc. It can convert the dedicated protocol data output by PLC or controller into TCP/IP Ethernet protocol data and upload it to the upper monitoring system; At the same time, convert the Ethernet control instructions issued by the upper system into a dedicated protocol that can be recognized by the device, achieving remote control of on-site equipment. For example, I/O data from the PROFIBUS DP bus can be converted to Modbus TCP protocol and connected to an Ethernet based SCADA system, breaking down barriers between different communication buses.

2.2 High speed Ethernet data transmission

The module supports 10/100Mbps adaptive Ethernet interface and adopts full duplex communication mode, with stable data transmission rate and low latency, meeting the needs of industrial real-time control. In the data upload scenario, real-time data collection and transmission at the millisecond level (≤ 5ms) can be achieved to ensure that the upper system can timely obtain the operating status of on-site equipment; In the scenario of issuing control instructions, the response time for instruction transmission is ≤ 2ms, ensuring the accuracy and timeliness of remote control. In addition, the module supports data frame priority setting, which can assign high priority to critical control data to avoid transmission delays caused by network congestion and ensure that the core control process is not affected.

2.3 Network redundancy and high availability guarantee

In response to the high reliability requirements of industrial communication, the DAPI100 module supports dual Ethernet port redundancy configuration (1+1 redundancy), where two Ethernet ports can be connected to different network switches to form a redundant communication link. When the main communication link fails (such as network cable breakage or switch failure), the module can automatically switch to the backup link within 10ms without interruption of data transmission, ensuring the continuity of the communication network. At the same time, the module has a network fault self diagnosis function, which can monitor the link status in real time. When a link abnormality is detected, it is immediately fed back to the upper system through an alarm signal, making it easy for operation and maintenance personnel to quickly troubleshoot the fault.

2.4 Industrial grade anti-interference and environmental adaptation

The module adopts industrial grade electromagnetic compatibility design and has strong anti-interference ability. Through the built-in electromagnetic shielding layer and signal filtering circuit, it can effectively resist electromagnetic radiation, pulse interference, and voltage fluctuations in industrial sites, complying with the IEC 61000-4 series electromagnetic compatibility standards; The module power interface has overvoltage, overcurrent, and reverse connection protection functions, which can work stably within the voltage fluctuation range of DC 24V ± 20%, avoiding module damage caused by power supply abnormalities. In addition, the module supports a wide temperature range of -25 ℃~+60 ℃, with a relative humidity tolerance of 5%~95% (without condensation), and can adapt to industrial site environments with high temperature, high humidity, and high dust.

2.5 Flexible Configuration and Remote Management

The module supports multiple configuration methods, including local configuration through RS-232 debugging interface, web page configuration through Ethernet network, and centralized configuration through ABB dedicated configuration software (such as ABB Communication Studio). Operators can set module IP addresses, subnet masks, gateways, communication protocol types, data mapping relationships, and redundant parameters through the configuration interface, making the configuration process simple and intuitive. At the same time, the module supports SNMP network management protocol, and the upper management system can remotely monitor the module's operating status (such as communication speed, link status, CPU load) through this protocol, and achieve remote firmware upgrades without the need for on-site module disassembly, reducing maintenance costs.
