Product Introduction
In a distributed control system, communication between the controller and the plant network is just as important as the execution of control logic. A failure in this communication path can interrupt data exchange with other control nodes and supervisory systems.
The ABB CP800 is the communication processor module used in the Symphony Plus HPC800 controller architecture. Working alongside the HC800 control processor, it provides access to the PN800 Ethernet-based plant network. This division of responsibilities separates control processing from network communication, supporting large process-control applications that require substantial computing capacity and distributed system connectivity.
For facilities maintaining an existing HPC800 installation, the CP800 is an important replacement component. Exact hardware identification and compatibility with the associated controller base and terminal boards should be confirmed before procurement.

Important specification note: ABB’s product catalog identifies CP800 as the communication processor responsible for PN800 communications. Some electrical and memory specifications published by third-party sellers refer to the complete HPC800 controller or its HC800 processor. They should not automatically be treated as standalone CP800 specifications.
Field Applications & Technical Pitfalls
Typical Applications
1. Symphony Plus Distributed Control Systems
The CP800 provides the network communication function within the HPC800 controller. It supports connectivity between the local control architecture and the PN800 plant network.
2. Large-Scale Process Control
The platform is designed for demanding process-control applications. ABB specifies support for up to 30,000 function blocks and closed-loop control of up to 5,000 I/O points in under 250 milliseconds for the controller platform.
3. Redundant Controller Architectures
configurations can use redundant controller arrangements with bumpless switchover. The forms part of this architecture, working with the corresponding HC800 and associated mounting and communication hardware.
Three Replacement Checks Engineers Should Not Skip
1. Confirm the controller platform.
The discussed here belongs to the Symphony Plus architecture. Do not confuse it with similarly named ABB products or unrelated control panel models. Check the existing controller label and system documentation before ordering.
2. Verify the HC800 and MB810 arrangement.
The is designed to work with the HC800 control processor and MB810 mounting base. The complete assembly also uses the relevant communication terminal boards. Confirm the physical arrangement and required accessories against the installed configuration.
3. Check the PN800 network architecture.
Before replacement, review the plant network topology, controller configuration, communication connections, and redundancy arrangement. A module that matches the designation still needs to be configured correctly within the existing control system.
Field note: In an system, a communication-related fault should not immediately be attributed to the . Check the processor status, mounting-base connections, terminal-board interfaces, network cabling, and controller configuration as part of the same troubleshooting process.
Important: Do not treat as a standalone controller capable of replacing . The two modules perform different functions within the architecture.
Quality Control (QC) SOP & Transparency
Our inspection process for ABB modules focuses on model identification, physical condition, and communication-interface integrity.
- Model Verification: Confirm the designation and compare the module identification with the customer’s existing configuration.
- Visual Inspection: Examine the housing, PCB, connectors, communication interfaces, and mounting points for physical damage.
- Interface Inspection: Check the relevant connectors and terminal interfaces for bent pins, corrosion, or signs of improper handling.
- Functional Testing: Where a compatible setup is available, verify module startup, status indicators, and communication functions.
- System Compatibility Review: Confirm the intended , MB810, CTB810, and CTB811 arrangement where applicable.
- Final QA and Packaging: Record inspection findings and prepare the module for protective export packaging.
Live video inspection can be arranged after the goods arrive at our headquarters. A 12-month warranty is available, subject to order confirmation and the agreed product condition.
Frequently Asked Questions (FAQ)
Q1: What is the ABB used for?
The is the communication processor module of the ABB Symphony Plus controller. It provides Plant Network communications.
Q2: Is the a PLC CPU?
No. The is the Harmony control processor responsible for control execution. The provides the communication function within the architecture.
Q3: What is the relationship between and ?
They are complementary modules in the controller. The handles control processing, while the provides plant network communications.
Q4: Which mounting base is used with ?
The architecture uses the MB810 module mounting base. The complete assembly also includes CTB810 and CTB811 communication terminal boards, depending on the configuration.
Q5: Does the support redundant controller configurations?
Yes. ABB documents configurations with optional controller redundancy and bumpless switchover. The complete redundant arrangement must follow ABB’s system architecture and hardware requirements.
Q6: Can the directly replace an ABB ?
No. These modules have different functions. The is the control processor, while the is the communication processor. They are not direct substitutes.
Q7: What warranty and inspection support do you provide?
We offer a 12-month warranty, subject to order confirmation and product condition. Part-number verification, visual inspection, and applicable functional testing can be arranged. Live video inspection is also available after the goods arrive at our headquarters.
