Product Overview
The Yokogawa CP471-51 Processor Module is a high-performance, industrial-grade processor module designed specifically for use within the CENTUM VP distributed control system (DCS). As part / the field control station hardware, the CP471-51 ensures robust processing, control execution, and communication capabilities. It is capable / operating in dual-redundant configurations, contributing to fault-tolerant system architecture.
The CP471-51 is compatible with the following field control 件 types:
-
AFV30 series
-
AFV40 series
-
A2FV50 series
-
A2FV70 series
Its support for online replacement (hot-swapping) in redundant configurations enhances system availability and simplifies maintenance operations.

常见问题 (FAQs)
Q1: Is the CP471-51 compatible with older versions / CENTUM VP?
A1: No, it requires CENTUM VP Control Function version R6.05 or later.
Q2: Can CP471-51 replace CP461 directly?
A2: Replacement is possible but must be performed by a Yokogawa authorized service engineer. It cannot coexist with CP461 in redundant mode.
Q3: What happens if one CP471-51 in a redundant pair fails?
A3: The other CP471-51 module takes over seamlessly without interrupting control operations.
Q4: Does CP471-51 support explosion-pro/ installations?
A4: Yes, models with the -1 suffix are designed for explosion protection compliance.
Q5: Can users perform module replacement themselves?
A5: Only online replacement in dual-redundant configurations is user-accessible. Full replacements (e.g., CP461 to CP471) must be done by authorized engineers.
Q6: Which bus coupler modules are compatible with CP471-51?
A6: EC401 modules with style code S3 or later are required.
Q7: Is enhanced RFI protection available?
A7: Yes, the optional “/ERFI” Tokuchu code adds enhanced RFI resistance.
Q8: Is there a difference between CP471-00 and CP471-51?
A8: CP471-51 is a suffix-specific model variation for particular system and compliance requirements. Confirm model code according to installation location and application needs.
Q9: Can CP471 be used in simplex configurations?
A9: Yes, it supports both simplex and duplex (redundant) setups.
Q10: Are there any size limitations for the control cabinet?
A10: The compact design (199.5 x 149 x 32.8 mm) allows for easy integration into standard control cabinets.
