ABB 500CSP04 1MRB150051R2 Communication Processor

I. Positioning and Applications

• Series Affiliation: Communication Processor module of ABB AC 500 series PLC, primarily used to expand the system's communication capabilities and enable data interaction and device interconnection between different network protocols.

• Core Functions: Supports multiple communication protocols such as industrial Ethernet and fieldbus, connecting remote I/O, sensors, actuators, and upper-level systems as a master or slave station. Suitable for distributed automation systems and cross-protocol communication scenarios (e.g., data interaction between workshop and management layers).

II. Technical Parameters and Characteristics

Communication Interfaces and Protocols

• Integrated Interfaces:

• 2 RJ45 Ethernet interfaces (ETH1/ETH2), supporting 10/100Mbps auto-negotiation, configurable for different network segments or redundant connections.

• 1 RS-485/RS-232 serial port (DB9 interface), natively supporting Modbus RTU and ASCII protocols, with custom communication protocol capabilities.

• Protocol Support:

• Industrial Ethernet: EtherNet/IP, Modbus TCP, Profinet (requires configuration), EtherCAT (requires expansion module).

• Fieldbus: CANopen, DeviceNet (configurable via software), Modbus RTU (serial port).

• Other Protocols: Supports communication with SCADA systems (e.g., WinCC, iFIX) and HMI devices (e.g., ABB Panel series).

Performance Parameters

• Data Transmission Rate: Up to 100Mbps for Ethernet interfaces, up to 115.2kbps for serial ports.

• Concurrent Communication Capability: Supports simultaneous processing of multiple communication tasks (e.g., Ethernet master and serial slave working in parallel).

• Address Mapping: Enables mapping of remote I/O data to local PLC memory for real-time data exchange.

Electrical and Environmental Characteristics

• Power Supply: 24VDC (±20%), power consumption ≤8W.

• Isolation: Electrical isolation between power supply and communication interfaces (1500V AC/1min), with strong anti-interference capability.

• Mounting Method: 35mm DIN rail mounting, supports vertical/horizontal installation.

• Operating Temperature: -25°C ~ +60°C, humidity 5%~95% (non-condensing).

III. Application Scenarios

Distributed System Interconnection

• As an EtherNet/IP master station, connects remote I/O modules (e.g., ABB 500I/O series) to build distributed control systems.

• Communicates with Siemens devices and third-party sensors via Profinet protocol to achieve cross-brand equipment integration.

Cross-Protocol Data Conversion

• Converts data from Modbus RTU devices (e.g., instruments, frequency converters) to Ethernet protocols for upload to SCADA systems.

• In automobile production lines, connects robot controllers via CANopen to enable collaborative control of multiple devices.

Remote Monitoring and Management

• Utilizes Ethernet interfaces to communicate with cloud platforms (e.g., ABB Ability™), supporting remote program download and device status monitoring.

• In water treatment systems, connects flowmeters and pH sensors via serial ports, and sends aggregated data to the central control room via Ethernet.

IV. Interfaces and Wiring

Hardware Interface Layout

• Ethernet Interfaces: ETH1 and ETH2 can be independently configured with IP addresses, supporting switch cascading or redundant links.

• Serial Port: DB9 interface; in RS-485 mode, connect to bus terminals A/B; in RS-232 mode, connect to TX/RX/GND.

• Expansion Interface: Backplane bus interface for inserting into the CPU rack of AC 500 series PLC to communicate with the main controller.

Typical Wiring Example (Profinet Master)

• Ethernet interface connects to Profinet slave stations (e.g., Siemens ET200S) via network cables, requiring GSD file configuration.

• When connecting third-party devices via serial port, install 120Ω terminal resistors at both ends of the RS-485 bus to avoid signal interference.
