ABB CI873K01 3BSE058899R1 Communication Interface

Bus Protocol: Supports EtherCAT master mode with a maximum communication rate of 100 Mbps and data transmission cycles as short as microseconds, meeting high-speed real-time control needs.

Slave Capacity: A single module can connect up to 254 EtherCAT slaves, supporting large-scale networking for complex systems.

Synchronization Mechanism: Built-in high-precision clock synchronization (error ≤1 μs) ensures precise collaborative operation of multiple slave devices.

Data Transmission: Supports cyclic data (process data) and acyclic data (parameter configuration) transmission, compatible with master-slave and peer-to-peer communication modes.

Interface Design: Equipped with 2 EtherCAT interfaces (RJ45 or dedicated interfaces), supporting bus topologies (linear, tree, star) and network expansion via interface cascading.

Isolation and Protection: Adopts electrical isolation technology (isolation voltage ≥500V AC) for strong Electromagnetic Interference (EMI) resistance, suitable for harsh industrial environments; interfaces have built-in surge protection to enhance system reliability.

LED Indicators: Includes power (POWER), operation (RUN), communication status (EtherCAT, ERROR), and slave connection status indicators to reflect module working status in real time.

Fault Self-Checking: Supports module-level fault diagnosis (such as communication interruption, slave anomalies, clock synchronization errors), with diagnostic information uploaded to the monitoring system via the controller for quick problem localization.

Rail Installation: Compatible with 35mm DIN rails, directly insert into the I/O slot of the AC 800M controller, supporting horizontal or vertical installation; module spacing ≥10mm for heat dissipation.

Anti-Static Measures: Wear an anti-static wristband during installation to prevent electrostatic damage to chips.

Power Supply Wiring: Use 1.5mm2 shielded cables to connect to 24V DC power, with positive/negative poles corresponding to module terminals (+24V, GND); recommend a series 2A fuse.

EtherCAT Bus Wiring:

POWER (Green): Steady on → normal power supply; off → check power wiring, fuse, or controller power supply.

RUN (Green): Steady on → normal module operation; flashing → initializing or parameter configuration anomaly.

EtherCAT (Green): Steady on → normal bus communication; off → communication interruption (check cable connection, slave power, or address).

ERROR (Red): Steady on → module fault or slave anomaly; flashing → clock synchronization failure or slave timeout (check synchronization configuration or slave response).

Communication Interruption:

Excessive Synchronization Error:

Connects servo drives and encoders in CNC machines to achieve high-precision position control and speed synchronization.

Coordinates multi-axis movements in industrial robot systems to ensure accuracy in trajectory planning (e.g., welding, assembly scenarios).

Real-time collection of sensor data (e.g., material position, equipment status) in electronic manufacturing equipment (SMT chip mounters, AOI inspection devices) to control actuators for rapid response.

Communicates with frequency converters and pneumatic valves in packaging machinery to achieve synchronous control of high-speed sorting and packaging processes.

Connects vacuum valves, temperature controllers, and other devices in semiconductor production lines to meet real-time control needs in high-cleanliness environments.

Communicates with distributed I/O modules in new energy battery production lines to monitor parameter collection and adjustment for processes such as battery injection and packaging.
