Description

The ABB CBI22 is a compact PROFIBUS DP(Decentralized Periphery)bus coupler designed for the ABB AC 500 series of programmable logic controllers(PLCs).It serves as the communication gateway between a central PROFIBUS DP master(such as an AC 500 CPU or third-party PLC)and a local rack of ABB digital and analog I/O modules,enabling distributed control architectures with minimal wiring.

As a self-contained fieldbus node,the ABB CBI22 integrates communication,power distribution,and module addressing into a single DIN-rail unit—making it ideal for remote I/O stations in machine automation,conveyor systems,and process skids where centralized control is impractical.

Application Scenarios

At a logistics warehouse in the Netherlands,engineers needed to control 12 conveyor zones spread over 300 meters,each requiring sensors,motor starters,and safety switches.Running individual wires back to a central cabinet was cost-prohibitive.Instead,they deployed ABB CBI22 bus couplers at each zone,connected via a single PROFIBUS cable from the main AC 500-E controller.Each ABB CBI22 hosted 8–12 local I/O modules,reducing copper usage by over 80%and cutting installation time in half.When a photoelectric sensor failed in Zone 7,maintenance staff identified the fault instantly via the ABB CBI22’s diagnostic LEDs—no tracing cables required.In this application,the ABB CBI22 transformed a complex wiring challenge into a scalable,modular solution.

Technical Principles and Innovative Values

Innovation Point 1:Integrated Power&Communication in One Unit

The ABB CBI22 eliminates the need for separate power terminals or bus connectors—its built-in 24VDC distribution powers all downstream I/O modules through the same backplane,simplifying cabinet layout and reducing component count.

Innovation Point 2:True Plug-and-Play PROFIBUS Integration

With automatic baud rate detection and DIP-switch-free addressing(configured via software),the ABB CBI22 enables rapid deployment.Its official GSD file ensures compatibility with Siemens,Rockwell,and other PROFIBUS masters.

Innovation Point 3:Real-Time Diagnostics for Predictive Maintenance

The ABB CBI22 continuously monitors bus health and reports detailed status(e.g.,short circuit,termination missing)to the PLC.This allows early intervention before communication loss occurs—critical in 24/7 operations.

Innovation Point 4:Scalable Architecture Without Performance Penalty

Whether controlling 4 or 40 I/O points,the ABB CBI22 maintains deterministic cycle times thanks to ABB’s optimized data mapping and low-latency firmware—ensuring consistent performance across applications.

Application Cases and Industry Value

In a food packaging line in Italy,a manufacturer replaced hardwired relay panels with ABB CBI22-based remote I/O stations at each filling,capping,and labeling station.Connected via a single armored PROFIBUS cable,the system reduced panel size by 60%and enabled centralized diagnostics from the main HMI.During a hygiene audit,inspectors noted the clean,modular wiring as a best practice.Over two years,unplanned downtime dropped by 35%,largely due to faster troubleshooting enabled by the ABB CBI22’s clear fault indication.

Similarly,in a solar panel assembly plant in South Korea,the ABB CBI22 linked robotic arms,vision systems,and vacuum grippers across a 50-meter production line.Its robust RS-485 transceiver handled EMI from nearby welding stations without data corruption—proving reliability even in electromagnetically harsh environments.

Installation,Maintenance,and Full-Cycle Support

Installing the ABB CBI22 begins with mounting it on a DIN rail and connecting 24VDC power plus a PROFIBUS cable(with proper termination resistors at both ends of the segment).I/O modules snap directly onto its right side—no backplane or ribbon cables needed.Addressing is done entirely in ABB’s Automation Builder or Control Builder M,using the provided GSD file;no physical switches are required.

Maintenance is simplified by front-facing LEDs:steady green=normal operation,flashing red=configuration error,solid red=bus fault.In redundant or critical systems,the ABB CBI22 supports hot replacement—minimizing line stoppage.Its wide temperature range and conformal-coated PCB options(available on request)ensure reliability in dusty or humid environments.

We provide fully tested ABB CBI22 units with verified communication logs,along with wiring templates,GSD files,and integration checklists.Our support includes compatibility validation for mixed-vendor PROFIBUS networks and lifecycle planning under ABB’s long-term availability program.
