The low power consumption model of the field control node (FCN) autonomous controller meets the demanding requirements at inhospitable remote locations which lack power.
*Depending on I/O modules
For steady operations, high reliability is an essential requirement in the systems that controls and acquires data from various devices and processes and which interlink with other controllers in the control domain. The STARDOM autonomous controllers FCN-RTU have rugged and highly reliable software and hardware.
FCN-RTU has a highly durable design. In addition to features such as fan-less cooling, there are no IC chips on the backplane, preventing mechanical failures. Furthermore, the use of error check and correct (ECC) memory* prevents software failures.
FCN-RTU has received ATEX type n certification, FM approval and CSA certification and provides safe and secure control even in hazardous applications. Optional corrosion-proof coatings are also available.
Rich diagnostic functions make it possible to keep track of CPU temperature, SRAM memory status, and I/O module status. In addition to the diagnostic functions that are performed by the CPU, the analog input modules have embedded self diagnostic functions that can detect disconnected wires and short-circuits by continuously monitoring the loop status.
STARDOM capability of establishing connections to a various network types results in big cost reduction for the customers. Networkability of STARDOM autonomous controllers FCN-RTU designed for the hazardous area shows absolute advantage in the various applications requiring remote monitoring and operation.
Remote applications require the various types of modems for seamless connection with control and information networks using narrow bandwidth network infrastructure including public telephone lines, GSM/GPRS, satellite, and radio. To meet these requirements, the following network interfaces are prepared.
|Upper-level systems||Ethernet||VDS (TCP/IP), FAST/TOOLS (TCP/IP, DNP3, Modbus TCP), HIS (Vnet/IP via gateway)
Other vendor SCADA systems (OPC, DNP3, Modbus TCP)
|Serial (RS-232, RS-422/485)||FAST/TOOLS (Modbus RTU/ASCII), Other vendor SCADA systems (Modbus RTU/ASCII, DNP3)|
|Other devices||Ethernet||FA-M3 (driver available), MELSEC (driver available), others (Modbus TCP)|
|Serial (RS-232, RS-422/485)||FA-M3 (driver available), MELSEC (driver available), others (Modbus RTU/ASCII)|
|Fieldbus||FOUNDATION™ fieldbus||FOUNDATION fieldbus devices|
|ISA100||ISA100 wireless devices|
FCN-RTU controller applications are written in programming languages compliant with the IEC 61131-3 international standard, so users do not need to learn manufacturer-specific programming languages and can start engineering immediately.
Concise applications can be developed by choosing the most suitable programming language for each application or the preference of the user from five IEC 61131-3 compliant languages including Function Block Diagram, Ladder Diagram, and Sequential Function Chart. Loop control and sequence control can be coded within the same environment, further improving engineering efficiency.
Engineering efficiency is improved by reusing the programmed and verified applications by using the following methods.
IEC 61131-3 compliant program allows your know-how to be encapsulated into reusable POU (Program Organization Units.) These POUs can be protected against user modification.
Network Template, which is a code frame programmed by FBD, LD, ST or IL, makes reuse of program easier. Network Template is inserted into any applications and modified corresponding to applications.
Virtual wiring to input/output modules can be defined in the software, and so loop checks and testing of ladder sequences can be performed without actual inputs to the FCN-RTU from a calibrator or test switches.
The simulator functions simulate the control applications of the FCN-RTU on a PC. Since this function does not require FCN-RTU hardware, control applications can be developed simultaneously by two or more engineers. Alternatively, applications can be developed and debugged separately from applications running on FCN-RTU.
Quick troubleshooting is the key to increasing the availability of the systems. From trouble shooting to the replacement of modules, STARDOM helps people on site perform simple maintenance procedures.
Expert engineers in the central control room can remotely check the CPU status on Web pages on the FCN-RTU.
Your application can be modified without interfering your process. By using online download functions on Logic Designer, application running on dual redundant CPUs is automatically synchronized and variables on the applications can be inherited.
Thanks to hot swappable I/O module features, I/O definitions are automatically downloaded to I/O modules without use of PC tools. While replacing I/O modules, rewiring cables are not required.
A TCP/IP based network enables a seamless connection with control and information networks using COTS network components, and also allow the easy adaption of controllers for use with narrow bandwidth network infrastructure including public telephone lines, GSM/GPRS, satellite, and radio.
STARDOM controllers act as Yokogawa DCS controllers via gateway. From a single window on the Yokogawa DCS HMI, operators enjoy seamless and transparent access to all the utilities on these different systems, with complete consolidation of all alarms.
STARDOM capability of establishing connections to a various network types results in big cost reduction for the customers. Networkability of STARDOM autonomous controllers designed for the hazardous area shows absolute advantage in the various applications requiring remote monitoring and operation.
STARDOM autonomous controllers are suitable for the geographically distributed area since software architecture is highly independent and control network easily adapts to the COTS network infrastructure.
Customers have already installed STARDOM autonomous controllers to a wide range of applications under various network infrastructures.

Yokogawa is pleased to present a tutorial on configuring the network IP address in a Stardom Hybrid RTU/PLC/PAC controller. The video walks the user through preparing the Stardom unit for initial network usage as it arrives from the factory or in the event that the IP address is unknown and needs to be rediscovered or altered.
Yokogawa presents a demonstration of how the combination of Stardom FCN-RTU and FAST/TOOLS SCADA can be combined to provide a powerful control and data collection system where in the event of a network disconnection or computer outage - Stardom internally buffers data that would otherwise be lost and on reconnection or restoration of the SCADA Server FAST/TOOLS is able to back-fill missing data in its trend.
Yokogawa's network control system, the STARDOM series, is designed to fulfill the industry requirements.
Yokogawa is pleased to present a quick tutorial on the Control Program Editor - Logic Designer for Stardom RTU/PLC/PAC Controller. This video covers the basics of the Logic Designer editor interface without getting into detail on controls programming.
Yokogawa is pleased to present a tutorial on downloading control projects from Logic Designer to the Stardom RTU/PLC/PAC controller.
Yokogawa presents a tutorial on configuring the Modbus Server communications capability of the Stardom RTU. A review of a preconfigured example (Example 11 under the Samples folder of Application Portfolio DVD) program featuring Modbus Client and Server capabilities is followed by a demonstration of how to create a configuration from a blank project - including which libraries need to be added to the Logic Designer programming environment. Note that Modbus capabilities for Stardom are an option that need to be licensed as part of CPU properties. Modbus library support can be purchased separately (FCN and FCJ model) and it is also included as part of the Infowell option. Modbus support comes standard on FCN-RTU (models SA0, SA1 and S10, S11).
