Function and Working Principle
The NQRC01 operates as a real-time fast-response control processor within the ABB Bailey DCS architecture.
Its working process can be summarized as:
- It receives process input signals from I/O modules
- Executes high-speed control algorithms internally
- Calculates output actions in short cycle intervals
- Sends updated control signals back to field modules
Compared with standard controller modules, it is optimized for low-latency processing and rapid loop execution, making it suitable for dynamic and fast-changing industrial processes.
The module ensures that control decisions are executed quickly enough to maintain system stability in time-sensitive applications.
