Yokogawa FCN FCJ Autonomous Controller

Yokogawa FCN FCJ Autonomous Controller

Description 

FCJ is an all-in-one controller with a built-in I/O interface — ideal for installing inside machine equipment as well as configuring a distributed system.  Its control network can be duplexed.  For hardware details, refer to FCJ Autonomous Controller Hardware, GS 34P02Q11-01E.

FCN-100 is a controller module consisting of CPU, I/O, and other modules as necessary. It supports a variety of I/O modules, provides a highly reliable system with duplexed power supply, CPU and control network options as well as superb scalability. For hardware details, refer to FCN Autonomous Controller Hardware (FCN-100), GS 34P02Q12-01E.

• The term “FCN-100” refers to the autonomous controllers with NFCP100 CPU module. 

• The term “FCN-RTU” refers to the low power autonomous controllers with NFCP050 CPU module. 

• The term “FCJ” refers to the all-in-one type autonomous controllers.

FEATURES

High Performance

• Applicable to a variety of processes, from sequence control processes to analog control processes. 

• Intercommunication with other autonomous controllers or other equipment for inter-linked control actions, in addition to stand-alone operation. 

• Using Versatile Data Server Software (VDS) or Supervisory Systems (FAST/TOOLS) together allows a system with enriched operation and monitoring functions to be built up. 

• An FCN/FCJ OPC server for Windows can be used for accessing the data of an FCN/FCJ from an OPC (OLE for Process Control) client on a PC.

High Reliability

• RAS features (CPU self-diagnostics, temperature monitoring, I/O diagnostics, and more) 

• Memory with error-correcting code (ECC) 

• Low heat dissipation, eliminating the need for a cooling fan 

• The Ethernet control network, CPU, power supply module, and SB bus (FCN local bus) can all be duplexed for an FCN-100. 

• The control network can be duplexed for an FCJ.

Engineering Efficiency

• Five IEC 61131-3 compliant programming languages are supported, enabling the user to selectively use these languages according to their purposes of use and applications. 

• Control logic can be encapsulated into software parts for reuse, allowing efficient and quality system configuration.

Easy Maintenance

• Online download function allows a control application to be modified during system operation 

• All modules are hot-swappable with an FCN-100.

Specification of FCN-100 with Duplexed CPU Modules 

• After a failure of the CPU in service, the stand-by CPU obtains the control right instantaneously and resumes control without any influence of the CPU switchover.

• Synchronization is periodically performed between the in-service CPU and stand-by CPU. The total processing time is hence longer than that of an FCN- 100 with single CPU. 

• If the control application comprises multiple tasks, those tasks cannot access the same global variable. 

• The CPU module’s serial port cannot be used.

Online Download Function 

• Online download function is a feature with which control applications can be modified while a control function continues in operation. 

• With this feature, I/Os, variables, data types, program codes, and libraries can be added, deleted or modified. 

• Modifying the control loop during system operation does not affect other control loops. Changing a range of control loop or loop connection causes the control loop to become the MAN mode.
