The ABB 3BUA000111R1, also known as the CI862K02, is a specialized communication interface kit designed for the AC 800M controller series, enabling seamless integration and high-speed data exchange with TRIO I/O systems to extend the capabilities of industrial process automation.
Product Introduction
The CI862K02 acts as a vital bridge within the ABB Ability System 800xA architecture, specifically serving as an interface between the AC 800M controller and the TRIO remote I/O legacy systems. This kit, identified by part number 3BUA000111R1, allows users to maintain their existing TRIO I/O investments while upgrading their control logic to the modern AC 800M platform. It is engineered to provide a reliable, deterministic communication link, ensuring that field data is processed with the precision required for complex industrial operations.
Product Technical Description
Technically, the CI862K02 is a CEX-bus (Communication Expansion bus) module that mounts directly onto the side of an AC 800M CPU or a communication expansion base. It supports the TRIO protocol, managing the master-slave relationship between the controller and the remote I/O blocks. The module handles the protocol conversion and data mapping internally, relieving the main CPU of communication overhead. It features robust electrical isolation to protect the control core from field disturbances and includes onboard diagnostics to monitor the health of the communication link in real-time.
Product Parameters and Datasheet
The technical parameters of the CI862K02 include a nominal power consumption from the CEX-bus of typically 24V DC. The module supports a maximum of two TRIO links per interface, with a significant number of I/O points manageable per link depending on the configuration. It is designed for an operating temperature range of 5°C to 55°C and features a compact, modular housing that snaps easily into the expansion slot. Detailed datasheet specifications confirm its compliance with CE and marine standards, making it suitable for both land-based and offshore installations.
Country of Origin
The ABB 3BUA000111R1 / CI862K02 is manufactured in Sweden, originating from ABB’s primary development centers for high-end control system hardware.
Application Fields
This interface module is primarily used in brownfield plant upgrades within the chemical, pharmaceutical, and pulp and paper industries. It is the go-to solution for facilities transitioning from older Geamatics or MOD 300 systems to the 800xA platform without the need to replace existing field wiring and I/O hardware.
Product Usage Instructions
To use the CI862K02, it must be physically attached to the AC 800M controller’s CEX-bus and secured. Configuration is performed within the ABB Control Builder M software, where the user must define the TRIO bus parameters and map the I/O addresses to the controller tags. It is critical to ensure the CEX-bus cables are properly terminated and that the total power load on the bus does not exceed the power supply capacity. During commissioning, the status LEDs on the front panel—labeled RUN, ERR, and LINK—should be monitored to verify successful initialization and active data traffic.
Q&A – Frequently Asked Questions
Q: Can I use the CI862K02 with an AC 800M PM861 controller? A: Yes, it is compatible with the AC 800M range, including PM861, PM864, and PM866, provided there is an available slot on the CEX-bus.
Q: Does this module support redundant configurations? A: The CI862K02 itself is a single module, but redundancy can be achieved at the system level by using two modules in a redundant AC 800M controller pair.
Q: What does the “K02” suffix indicate? A: The “K” suffix usually denotes a kit that includes the module itself along with necessary mounting components or specific firmware revisions required for immediate installation.
