ABB H&B Freelance 2000 is an integrated process control system developed by ABB for small to medium-sized processes and hybrid industries. It combines the flexible programming of PLCs with the integrated engineering environment of DCS, achieving seamless configuration of logic control, HMI, and fieldbus through the unified Control Builder F software platform. It provides a cost-effective, modular, and easy-to-maintain solution for medium-sized automation projects.

The core advantage of ABB H&B Freelance 2000 lies in its

Freelance 2000 achieves efficient integration with upper-level systems (such as SCADA/MES) through its built-in multi-protocol communication interface; it also provides SQL database connectivity and web publishing capabilities, and can interface with cloud platforms through the ABB Ability™ edge gateway.

Its core uses include achieving stable control of continuous production processes (such as chemical and water treatment), handling mixed logic combining discrete and process flows (such as packaging and batching), and reducing project design and maintenance complexity through an integrated engineering environment.

Freelance 2000 offers optional redundancy solutions covering multiple levels, including controllers, networks, power supplies, and operator stations: supporting hot standby redundancy for critical controllers (switching time ≤ 100 milliseconds), ring or dual-star communication network redundancy, and dual power supply module backup.
