Function and Working Principle
The NPBS01 operates as a slave communication module on the parallel bus system within ABB Bailey distributed control architectures.
It receives data signals from the system bus and passes them to connected modules such as controllers, I/O units, or interface devices. At the same time, it responds to system requests by transmitting processed or buffered data back onto the bus.
This allows multiple modules in the system to share information in real time, ensuring synchronized operation across the control network.
The module plays a key role in maintaining stable data exchange and coordinated system communication in high-density industrial control environments.
