YOKOGAWA Turbomachinery Controller Overview (FCN-500/FCN-RTU)

OVERVIEW

The General Specifications (GS) describe the features, functions, system configuration examples, engineering

environment, software operating environment, hardware configuration, installation environment, and compliant

standards of a turbomachinery controller using the STARDOM FCN autonomous controller, and outline the functions

of turbomachinery I/O modules.

As for the FCN, refer to “FCN-RTU Low Power Autonomous Controller Hardware” (GS 34P02Q13-01E), “FCN

Autonomous Controller Hardware (FCN-500)” (GS 34P02Q14-01E), “FCN-RTU Low Power Autonomous Controller

Functions” (GS34P02Q02-01E) and “FCN Autonomous Controller Functions (FCN-500).” (GS34P02Q03-01E)

 FEATURES

●    FCN-based    Turbomachinery    Controller

The FCN autonomous controller can be applicable to a variety of processes from sequence control processes to

analog control processes. A wide variety of types of I/O modules are supported and a flexible system configuration

can be selected according to purpose.

Applying an FCN-based turbomachinery controller to the control of generator turbines or other turbomachinery such

as compressors also enables control of their ancillary facilities.

The CPU module, power supply, and communication can be made redundant for applications that require high

reliability.

●    Turbomachinery    I/O    Modules

Combined use of an FCN autonomous controller and turbomachinery I/O modules makes it possible to control and

protect turbomachinery such as turbines and compressors. With the STARDOM turbomachinery controller, a flexible

system can be constructed according to the scope of control and the installation space.

Of the turbomachinery control and protection functions, processing that requires high speed response is carried out by

the turbomachinery I/O modules. There are two types of turbomachinery I/O modules: a servo module that performs

high speed servo control in a cycle of 5 ms and a high speed protection module that performs a high speed protection

action in a fast scan (5 ms) or a standard scan (10 ms).

    FUNCTIONS

The primary functions of a turbomachinery controller comprise of regulatory control of the turbomachinery speed,

load, and fluid pressure, and so on, and protection of the turbomachinery from anomalies. Control and monitoring of

ancillary facilities can also be added if necessary.

●    Configuration    Types

There are two types of configuration for the STARDOM turbomachinery controller.

Type 1: Configuration with a FCN-RTU

Type 2: Configuration with a FCN-500
