Functions & Features
Multi-Protocol Communication & Broad Compatibility
Built with a complete protocol stack, it supports mainstream industrial communication protocols including PN800 (10/100 Mbps industrial Ethernet), PROFIBUS DP, Modbus TCP, EtherNet/IP, and IEC 61850. It enables seamless interconnection with S800 I/O modules, third-party PLCs, smart instruments, and the 800xA system. Via the IOR810 gateway, it can directly interface with the S800 I/O subsystem and supports fiber-optic Modulebus connections to meet long-distance distributed I/O communication requirements of up to 3 km.
High Performance & Real-Time Control
Equipped with a 256 MHz ColdFire 32-bit processor, it works in coordination with the HC800 control processor to support the HPC800 controller in handling 30,000 function blocks and implementing closed-loop control for 5,000 I/O points with a scan cycle as low as 250 ms. It supports independent operation of 8 segment tasks, with a minimum single-segment cycle of 1 ms, suitable for high-precision, fast-response process control applications.
Redundancy & High-Reliability Design
Fitted with a dedicated redundant peer-to-peer communication bus with a failover time of less than 100 ms, it provides redundant backup between controllers and communication links to prevent system shutdown caused by single points of failure. The module supports hot swap and online reconfiguration, allowing maintenance or configuration updates without system shutdown, greatly improving system operating efficiency and availability.
Industrial-Grade Environmental Adaptability
Features a robust modular DIN-rail mounting design and supports wide-temperature operation from -40 °C to +70 °C. Compliant with ISA 74.01 G3 conformal coating standards, it withstands harsh field conditions such as humidity, dust, and strong electromagnetic interference. Optimized power consumption control delivers a typical power draw of approximately 10 W per module, balancing energy efficiency and stable operation.
Comprehensive Diagnostics & Maintenance Capabilities
Integrates extensive diagnostic functions for real-time monitoring of communication status, data transmission quality, and module health. It supports fault alarms and event logging to facilitate quick troubleshooting. Used with the S+ Engineering tool suite, it enables remote configuration and firmware downloading, reducing on-site maintenance costs.

FAQ
Q: How is the CP800 module connected to S800 I/O?A: It connects via the IOR810 S800 I/O gateway, which communicates with the CP800 over fiber-optic Modulebus, supporting long-distance transmission up to 3 km. A single gateway can interface with the full range of S800 I/O modules and supports redundant configuration.
Q: How is redundancy configured for the CP800 module?A: The HPC800 controller (including CP800) supports 1:1 redundancy with a dedicated redundant peer-to-peer communication bus. Data is synchronized in real time between primary and backup controllers. If the primary link or module fails, the backup switches automatically within 100 ms without manual intervention.
Q: Which communication protocols does the CP800 support? Is it compatible with third-party devices?A: It supports mainstream protocols including PN800, PROFIBUS DP, Modbus TCP, EtherNet/IP, and IEC 61850. It can directly connect to ABB’s full range of I/O modules, third-party PLCs, and smart instruments, enabling cross-brand interoperability via protocol conversion.
Q: How to quickly troubleshoot communication failures on the CP800 module?A: Diagnostic information such as communication status, packet loss rate, and fault codes can be viewed remotely via S+ Engineering. Onsite, fault types can be identified from module indicators. Modules can be replaced using hot swap to restore communication without system shutdown.
Q: How to update the firmware of the CP800 module?A: Online firmware download is supported. After connecting the module via S+ Engineering, firmware can be uploaded and updated directly while the system remains running, without affecting normal control tasks.
