FAQ
Frequently Asked Questions (FAQ)
Q1: What is the primary function of the CP401-11 module?
A1: The CP401-11 serves as a dual-redundant processor module in Yokogawa’s FFCS control station, handling control logic and data processing.
Q2: What is the advantage of the Pair & Spare technology used in CP401-11?
A2: Pair & Spare ensures high reliability by running two MPUs in parallel, comparing outputs in real-time to detect and correct transient errors without disrupting operations.
Q3: Is the CP401-11 suitable for high-availability applications?
A3: Yes, its redundant configuration and error-detection capabilities make it ideal for critical industrial automation systems requiring high availability.
Q4: What type of memory is used in the CP401-11?
A4: The module uses ECC-protected main memory, enhancing fault tolerance against memory errors.
Q5: Can CP401-11 modules be hot-swapped?
A5: Yes, they support live insertion/removal under electrified conditions thanks to the SEN bus design.
Q6: What kind of battery does the CP401-11 use and why?
A6: It uses a nickel-hydrogen battery for memory backup, replacing nickel-cadmium types for environmental considerations.
Q7: What is the SEN bus used for in the CP401-11?
A7: The SEN bus is a serial high-speed communication interface used for program copying and data equalization between redundant processor modules.
Q8: Is the CP401-11 compatible with older CENTUM CS3000 components?
A8: Yes, it reuses proven hardware such as the CP345 and SB301, maintaining backward compatibility where possible.
