ABB CI670 3BHT300017R1 Masterfieldbus Interface, Slave

I. Overview

The ABB CI670 3BHT300017R1 is an EtherNet/IP interface module designed for high-speed Ethernet communication in industrial automation systems. Its core positioning is a "high-bandwidth data interaction hub between ABB AC 800M controllers and EtherNet/IP devices". Its core value lies in establishing a high-speed data transmission network of "AC 800M Controller - Distributed EtherNet/IP I/O - Third-party Intelligent Devices - Industrial Cloud Platform" through in-depth adaptation to the EtherNet/IP protocol, gigabit Ethernet transmission architecture, and redundant communication design. It provides an integrated solution of "high-speed protocol conversion + redundant communication guarantee + multi-device compatibility" for industries such as automotive manufacturing, high-end equipment, and logistics automation that have strict requirements for communication bandwidth (e.g., real-time transmission of large data volumes) and synchronization accuracy (e.g., microsecond-level device collaboration). This addresses the core pain points in industrial systems, including data transmission bottlenecks, difficult device interconnection, and insufficient real-time performance.

• It supports a gigabit Ethernet rate (1000Mbps), with a single-module data transmission capacity 10 times that of ordinary 100Mbps modules, meeting the needs of high-definition visual inspection and concurrent upload of large amounts of sensor data.

• Specifically designed for the AC 800M controller, it can be seamlessly integrated into the ABB System 800xA automation platform to achieve integrated configuration and monitoring of "controller - module - device" without the need for additional adaptation software.

Whether for real-time collaboration of multiple robots in an automotive welding line or large-volume AGV data interaction in a logistics sorting system, its high-speed transmission and stable redundancy capabilities ensure efficient and reliable system communication.

III. Functional Features

(I) Gigabit High-Speed Transmission to Break Through Data Bandwidth Bottlenecks

• Large-Volume Real-Time Data Interaction: With a 1000Mbps gigabit rate and ≥800Mbps throughput, it can simultaneously transmit I/O data from 64 slaves, 16 channels of high-definition visual inspection video streams (1080P/30fps), and device status parameters, with a data refresh cycle as low as 100μs. In an automotive body visual inspection production line, the CI670 can upload inspection data from 12 vision sensors (each generating 10MB of data per second) to the AC 800M controller in real time. The controller quickly identifies body welding defects through data analysis, reducing the inspection response time to 500μs and improving the production line qualification rate.
• Long-Distance Fiber Optic Expansion: An optional SFP optical port supports fiber optic transmission, with a transmission distance of ≤10km for single-mode optical fiber and ≤550m for multi-mode optical fiber. This is suitable for cross-workshop communication in large factories (e.g., between the cell workshop and assembly workshop of a new energy battery factory, 3km apart), avoiding signal attenuation and electromagnetic interference in copper cable transmission and ensuring stable data transmission (bit error rate ≤10⁻¹²).

(II) In-Depth AC 800M Integration for Integrated Management and Control

• Seamless System Connection: Specifically designed for the AC 800M controller, it is directly inserted into the controller rack and communicates via the internal bus, requiring no additional wiring. It is compatible with ABB Control Builder M configuration software, enabling EtherNet/IP slave mapping (e.g., associating AI signals of Rockwell 1756-I/O with AC 800M variables), synchronization parameter configuration (e.g., CIP Sync clock source setting), and online debugging in the same environment, improving configuration efficiency by 50%. For example, in a high-end equipment workshop, engineers can configure 20 EtherNet/IP slaves in just 30 minutes via Control Builder M without switching between multiple software tools.
• System 800xA Linkage: It supports real-time data interaction with the ABB System 800xA platform, allowing parameters such as network load rate, slave communication status, and synchronization accuracy to be uploaded to the 800xA HMI. Maintenance personnel can monitor the module's operating status through a visual interface (e.g., "Primary network load rate: 70%", "Slave 12 synchronization error: 0.5μs"), and an audible and visual alarm is automatically triggered in case of anomalies, eliminating the need for on-site network fault troubleshooting.

(III) Multi-Redundancy and Safety Design to Ensure Communication Reliability

• Multi-Level Redundancy Protection: Network redundancy (primary-backup dual-network switching time ≤5ms) ensures uninterrupted data transmission if an Ethernet link fails. For example, in a logistics sorting system, if the primary network switch fails, the CI670 immediately switches to the backup network, maintaining uninterrupted AGV scheduling data transmission and avoiding sorting stagnation. Device-level redundancy (active-standby hot backup for master and slave stations) and power redundancy further reduce the risk of failures, increasing system availability to 99.999%.
• Safety-Level Data Transmission: It supports the CIP Safety protocol and SIL 2 certification, enabling the transmission of safety signals such as emergency stops and safety door status. Data transmission adopts triple protection of "message encryption (AES-256) + CRC verification + timestamp verification" to prevent data tampering or delays. In an automotive welding line, the CI670 transmits robot emergency stop commands (safety signals) to the AC 800M via the CIP Safety protocol, with a response time ≤1ms, ensuring the safety of personnel and equipment.

(IV) Multi-Brand Device Compatibility to Reduce System Expansion Costs

• Cross-Brand Interconnection: It is compatible with EtherNet/IP devices from major brands such as Rockwell, Schneider, and Omron. It supports importing device EDS files (electronic data sheets) to automatically identify device models and I/O channels, eliminating the need for manual writing of communication drivers. In a new energy vehicle battery production line, the CI670 can simultaneously connect to a Rockwell 1756-L8 controller (for cell liquid injection control), a Schneider M340 PLC (for battery assembly control), and ABB robots (for handling), enabling unified communication of multi-brand devices and avoiding additional investment in protocol conversion modules.
• Flexible Protocol Expansion: The Modbus TCP protocol can be enabled via software configuration to realize interconnection between EtherNet/IP and Modbus TCP devices (e.g., converting EtherNet/IP sensor data into Modbus TCP signals for upload to a third-party SCADA system), adapting to the upgrade scenario of existing factory equipment. For example, in the renovation of an old water plant, the CI670 converts data from newly added EtherNet/IP flowmeters into Modbus TCP signals, which are connected to the existing Modbus monitoring system without replacing the upper-level software.

(V) Industrial-Grade Environmental Adaptation and User-Friendly Maintenance to Reduce Operating Costs

• Harsh Environment Resistance: The wide temperature range of -25℃ to +60℃ covers outdoor control cabinets in northern winter and high-temperature workshops in southern summer. The resistance to ±8kV ESD contact discharge and 30V/m RFI radiation immunity defends against industrial electromagnetic interference (e.g., from frequency converters and high-voltage motors), ensuring a communication bit error rate ≤10⁻¹² at the gigabit rate. The RJ45 interfaces are equipped with dustproof and waterproof covers (IP40 protection), and the optical fiber interfaces adopt an LC anti-misinsertion design, extending the interface service life to more than 5 years.
• Convenient Maintenance and Diagnosis: The Mini USB interface supports local parameter configuration (e.g., modifying IP address, synchronization cycle) and exporting fault logs (including fault time, cause, and affected devices). The gigabit network port supports remote firmware upgrade (pushed online via Control Builder M), eliminating the need for on-site trips for maintenance of remote sites. The module has built-in network diagnostic tools (e.g., ping, traceroute) to quickly locate network breakpoints (e.g., "Slave 15 route loss"), reducing fault troubleshooting time to 20 minutes.
