ABB 500SCM01 1MRB150004R0001 1MRB200059/C Communication Module

Operating voltage: 24 VDC (powered by the rack power supply module).

Power consumption: Typical value ≤5 W.

Isolation protection: Electrical isolation between Ethernet interfaces and internal circuits (isolation voltage 1500 VAC) for electromagnetic interference resistance.

Maximum Ethernet throughput: Approximately 80 Mbps (depending on protocol load).

Serial interface baud rate: Adjustable from 1200 to 115200 bps.

Ring Network Support: FastTrack redundant ring networks can be formed via Ethernet interfaces, with self-healing time <50 ms during faults to ensure communication continuity.

Disconnection Detection and Recovery: Supports real-time network status monitoring, automatically triggering alarms and attempting reconnection when disconnections occur.

Can act as a protocol gateway to enable data conversion between EtherNet/IP and Modbus RTU networks (e.g., connecting third-party Modbus devices to Ethernet).

Supports concurrent operation of multiple protocols (e.g., handling EtherNet/IP communication and Modbus RTU slave requests simultaneously).

Visually configure communication parameters and protocol mapping tables via Control Builder AC 500 software.

Panel LED indicators (Link, Activity, Error) display network status in real time, supporting fault early warning.

Ethernet interfaces: 2 RJ45 ports (labeled "NET1" and "NET2"), supporting direct connection or networking via switches.

RS-485 interface: 3-pin terminal block (+, -, GND), supporting shielded cable connections to reduce interference.

Status indicators:

Insert into the communication slot of the AC 500 rack, powered via the backplane bus.

Ethernet interfaces require IP address configuration (static or DHCP); enable the "FastTrack" function in software for ring network mode.

Create a Modbus TCP master task in Control Builder, specifying slave IP, port (default 502), and data mapping tables (e.g., reading holding register addresses 40001–40010).

Polling cycles (e.g., 100 ms) or event-triggered communication can be set.

If the Error light is on: Check network cable connections, IP address conflicts, or protocol parameter configuration errors.

For serial communication anomalies: Confirm that baud rate, data bits, and parity bits match the slave device, and inspect for loose wiring or poor grounding.

Strong compatibility: Simultaneously supports Ethernet and serial protocols, adapting to mixed networking of new and old devices.

High reliability: Ring network redundancy and electrical isolation designs meet anti-interference requirements in industrial fields.

Flexible configuration: Visual management of communication tasks via software reduces integration difficulty, suitable for data interaction scenarios in medium-to-large automation systems.
