Embedded ASPECT runtime and web UI centralize control and visualization, reducing software layering and cutting commissioning time. Feature → Business Impact → Application: With an integrated runtime and browser-based interface, engineers can deploy configurations quickly and monitor system health remotely, improving mean time to repair. This is ideal for building automation where rapid fault isolation is critical and where operators benefit from real-time visibility on BACnet/MS·TP devices and Modbus RTU networks. In practice, this enables faster problem resolution and lower on-site labor costs in HVAC and process plants. Dual RS-485 ports configured 9.6 to 115.2 kbps support BACnet MS/TP, Modbus RTU, or AAM PUP, reducing the need for external gateways and enabling seamless retrofits. Business impact: fewer interfaces to manage, reduced installation time, and improved data integrity across field devices. Application: retrofit projects in facilities where legacy HVAC controllers rely on MS/TP or Modbus RTU. One RJ-45 Ethernet port with TCP/IP supports BACnet/IP and Modbus TCP, plus FT/Net for streamlined network management. Business impact: centralized supervision and easier integration with SCADA and cloud-based analytics. Application: enterprise-grade building automation and energy-management systems. Network capacity supports up to 64 devices and 4,000 points, with field upgrade to 10,000 points and 128 devices—scalability that protects capital expenditure. Business impact: grow without replacing hardware, lowering per-point cost. Application: large campuses or multi-building installations. Operating from 24–36 V and rated IP20, the unit is designed for industrial environments, delivering reliable performance and easier installation. Business impact: robust operation and reduced protective enclosure requirements. Application: mechanical rooms, control cabinets, and retrofit projects in automation ecosystems. Compliance and lifecycle support include RoHS, WEEE, and CE declarations, ensuring procurement alignment with regulations. Business impact: faster supplier qualification and lower risk during audits. Application: regulated industries and asset management programs.

FAQs
The ABB 2CQG100111R2021 supports two RS-485 ports configurable for BACnet MS/TP and Modbus RTU, enabling direct integration with legacy field devices. This minimizes gateway hardware and reduces wiring complexity. For smooth onboarding, configure baud rates between 9.6 and 115.2 kbps and align device addresses prior to commissioning to prevent conflicts on multi-vendor networks.
The unit provides two RS-485 ports with 9.6–115.2 kbps configurability and an RJ-45 Ethernet port supporting TCP/IP for BACnet/IP and Modbus TCP. It handles up to 64 devices or 4,000 points, with a field upgrade path to 128 devices and 10,000 points. The supply is 24–36 V and the interface supports AC/DC input, with IP20 enclosure protection.
Yes. The controller scales from a base capacity of 64 devices and 4,000 points up to 128 devices and 10,000 points via field upgrades, preserving existing wiring and protocols. This design minimizes hardware replacement and downtime while supporting future expansion in large facilities, campuses, or complex industrial processes.
The device carries IP20 protection, CE declarations, RoHS compliance, and WEEE alignment, which simplifies procurement, approvals, and regulatory audits. Additional documentation includes a CE Declaration for NEXUS-3 Series and ETIM classification EC011487, aiding interoperability and supplier qualification in regulated environments.
The embedded runtime and web UI reduce commissioning time and on-site software maintenance, while multi-protocol support lowers gateway costs. Field upgradeability protects capital expenditure by delaying hardware replacement. Together, these factors shorten project timelines, cut labor costs, and improve ongoing system reliability across building automation and energy-management deployments.
