Yokogawa FCN Autonomous Controller  Hardware (FCN-500) 

 GENERAL 

 This document describes the general specifications of the FCN autonomous controller with NFCP501/ NFCP502 CPU module.  (FCN is an acronym for field control node.) Notation in this document: 

 • The term “FCN” refers to the module consisting type autonomous controllers. 

 • The term “FCN-500” refers to the autonomous controllers with NFCP501/NFCP502 CPU module. For Function, refer to FCN Autonomous Controller Functions (FCN-500), GS 34P02Q03-01E. 

 FEATURES 

 • High-performance, high-reliability modular controller 

 • Memory with ECC 

 • Low heat dissipation eliminates the need for a fan 

 • A wealth of RAS features — CPU self-diagnostics, temperature monitoring, I/O diagnostics, and more 

 • The CPU, power supply module, internal communication bus on backboard (SB bus), E2 bus (extension bus), and control network (Ethernet port 1 and 2) can all be duplexed, and all modules are hot-swappable. Use a couple of the CPU module of the same type to make the CPU module duplex configuration. 

 • Can function as link active schedulers (LASs) for low-speed voltage mode (H1) FOUNDATION Fieldbus segments, and link up FOUNDATION Fieldbus-enabled field devices.

 CONFIGURATION 

 An FCN-500 consists of the following: 

 • Base module

 • Power supply module

 • CPU module • E2 bus interface module (extending the unit) (1)

 • SB bus repeat module (extending the SB bus to connect an extension unit) (1) 

 • I/O modules 1: SB bus repeat module and E2 bus interface module can not be used together. 

 There are four types of base module.- NFBU200 base module (long):  - N2BU051 base module (short):  

- NFBU050 base module (short):  

- N2BU030 base module (compact): l Control unit alone Control unit and extension unit sharing,   duplexed power supply possibility Control unit and extension unit sharing Control unit only, for low power Control unit and extension unit sharing The control unit is unit with CPU module. The maximum number of I/O modules that can be implemented depends on the type of base module and the number of CPUs.
