Name: Yokogawa STARDOM FCN-500 Controller – Datasheet & Quote
Brand: Yokogawa

Description

Overview

The Yokogawa STARDOM FCN-500 is an autonomous field control node (FCN) that delivers reliable, high-performance control in distributed and remote applications, using the rugged NFCP501 or NFCP502 CPU modules at its core.

Designed for mission-critical control, the FCN-500 provides a wealth of RAS (reliability, availability, serviceability) features including memory with ECC, CPU self-diagnostics, temperature monitoring, and I/O diagnostics, in a fanless modular architecture with hot-swappable modules.

Engineering & Design

The FCN-500 is built for maximum availability: the CPU modules, power supply modules, internal SB bus, E2 extension bus, and both control network Ethernet ports can all be configured in duplex, with all modules hot-swappable for online maintenance.

Low heat dissipation eliminates the need for cooling fans, and the control unit supports up to eight extension units via E2 bus interface modules, scaling from compact single-unit installations to large distributed control solutions.

Control System Support

Seven Star LLC supports STARDOM system planning, including FCN-500 module selection, Foundation Fieldbus segment design, and integration with CENTUM control systems.

Our specialists provide spares strategy guidance for long-term support of your distributed control infrastructure in oil, gas, and utility applications.

Operational Benefits

The FCN-500 provides a future-proof control platform that scales from standalone field control to large distributed architectures with redundant, hot-swappable modules.

Its fanless design and RAS features reduce maintenance exposure and improve availability in remote field locations.

Foundation Fieldbus and Ethernet integration options allow cost-effective consolidation of field devices under a single controller.

Duplex-capable architectures and hot-swappable modules keep the FCN-500 maintainable without process interruption.

The modular FCN-500 architecture simplifies future expansion and protects the control system investment.

For control systems that must run continuously, Seven Star LLC supplies the Yokogawa STARDOM FCN-500 with full documentation, and our specialists configure each controller for your architecture.

The FCN-500 controller provides the high speed control and the communication functions of the STARDOM system, and the controller supports the IEC 61131-3 programming for the process control.

The controller is available with the redundant CPU option, and the FCN-500 supports the fieldbus and the serial communication for the integration.

The Yokogawa STARDOM FCN-500 autonomous controller runs the process control and the logic sequences without a host system, and the dual-redundant CPU option increases the availability of the station. The controller is programmed in FBD and ST through the VDS engineering environment, and it communicates with the plant network over the redundant Ethernet ports. The FCN-500 is installed in the 19-inch cabinet with the baseplate and the dedicated I/O modules of the STARDOM family.

Configuration and Selection

An FCN-500 system is built from individual modules, so a clear bill of materials is essential. When planning a new node or ordering spares, confirm:

CPU module: NFCP501 or NFCP502, and whether the node runs single or duplex CPUs.
Base modules and power supplies for the control unit and any extension units.
I/O module types and channel counts, including Foundation Fieldbus H1 interfaces where used.
E2 bus interface modules and cables for extension units.
Control network design: single or duplex Ethernet, and the connection to the SCADA or CENTUM system.

For spares, the model and suffix codes on each module label should be recorded exactly, together with the software revision used on site.

Installation and Commissioning

Install the node in a cabinet with adequate ventilation; the fanless design depends on natural cooling. Mount base modules, fit modules in the positions defined in the engineering configuration, and connect duplex network cables and E2 bus cables carefully so each redundant path is correctly labelled. After power-up, download the configuration and application, then check diagnostics for every module, test redundancy switchover on CPUs, power supplies and networks where duplexed, and verify I/O loop by loop.

Maintenance and Troubleshooting

Monitor the RAS diagnostics for temperature, memory and I/O alarms rather than waiting for a failure.
Use hot-swap replacement for failed modules, following Yokogawa procedures and site permits.
If a duplex pair is running on one side, restore redundancy promptly; the system is then without its backup.
Keep backups of the application and configuration, and record module revisions after each change.

Oman and GCC Applications

In Oman, the Yokogawa STARDOM FCN-500 suits oil and gas wellpads, pipeline block valve stations, water transmission and utility sites where a robust controller must run in remote shelters with limited maintenance visits. Cabinet temperature control is important in these shelters because summer heat shortens electronic life.

About brand

Yokogawa instruments are ordered by model and suffix code, a string such as EJX110A followed by option characters that fix span, materials and approvals. Founded in 1915 and headquartered in Tokyo, Yokogawa makes field instruments, process analyzers and the CENTUM control system used in refineries, gas plants and power stations.

Seven Star LLC is an independent supplier listing Yokogawa pressure transmitters, flowmeters, temperature transmitters, analyzers and CENTUM I/O modules for users in Oman and the GCC.

Yokogawa product families on this page

Pressure is covered by the DPharp transmitters: the EJX110A differential pressure transmitter, the EJX530A and EJA530E in-line gauge pressure transmitters and the EJX910A multivariable transmitter. The ADMAG AXW is the magnetic flowmeter line, and the YTA610 and YTA710 are temperature transmitters. Analyzers include the FLXA402 four-wire and FLXA21 two-wire liquid analyzers, the TDLS8000 tunable diode laser gas analyzer and spare parts for zirconia oxygen analyzers, such as the E7042UD cell assembly kit for the ZR22 detector. Control hardware includes CENTUM VP I/O modules like the ADV161 digital input module and the YS1700 programmable indicating controller.

Where Yokogawa instruments are used

EJA and EJX transmitters measure pressure, level and DP flow throughout oil and gas, chemical and power plants. Zirconia oxygen analyzers and the TDLS8000 are used for combustion control on boilers and fired heaters. FLXA analyzers monitor pH, conductivity and dissolved oxygen in water and process streams, and CENTUM modules are bought as replacements for running control systems.

Ordering Yokogawa parts: what we need

Send the model and suffix code and the serial number from the nameplate, and for CENTUM modules the style code as well. For transmitters without a code we need span, output protocol, wetted materials, process connection, housing and the approval required. For oxygen analyzer spare parts give the detector and converter models, for example ZR22G and ZR402G, and the part number.
