NFCP050-S00

The Yokogawa NFCP050-S00 is a CPU module specified for the STARDOM FCN-RTU autonomous controller platform. It combines control processing, onboard memory, embedded digital and analog I/O, pulse inputs, and serial and Ethernet communications. The listed configuration includes an SH-4A processor, ECC memory, and fanless cooling. These features define its processing, signal-handling, and communication roles in a distributed control application.

Processing and Memory

The listed SH-4A (SH7730) processor operates at 256 MHz. The memory configuration comprises 128 MB of main memory with error-correcting code (ECC), 1 MB of ECC static RAM, and 128 MB of onboard flash memory. ECC helps detect and correct certain memory errors, supporting data integrity during controller operation.

Embedded I/O Configuration

The supplied specifications list the following onboard channels:

• 16 digital inputs (DI) for discrete status signals.
• 8 digital outputs (DO) for discrete control signals.
• 12 analog inputs (AI) for process measurements.
• 2 analog outputs (AO) for control references or other analog signals.
• 2 pulse inputs (PI) for pulse-based signals.

The channel counts describe the listed I/O configuration. Electrical signal ranges, channel isolation, output drive ratings, and supported sensor types are not specified in the supplied material and should be verified before wiring or selecting field devices.

Communication Interfaces

The supplied configuration identifies 10/100 Mbps Ethernet and built-in serial interfaces supporting RS-232 and RS-485 communication. Ethernet supports TCP/IP and UDP/IP networking, with Modbus TCP listed as an application protocol. Serial communication supports Modbus RTU. Yokogawa's FCN-RTU documentation confirms that the NFCP050 provides Ethernet and serial communication interfaces.

Programming and Runtime Environment

The CPU module supports IEC 61131-3 programming languages, including Ladder Diagram (LD), Function Block Diagram (FBD), Structured Text (ST), Instruction List (IL), and Sequential Function Chart (SFC), as listed in the supplied material. Its Java Virtual Machine environment supports Java-based applications. The availability of individual application portfolios and software functions depends on the controller's installed software configuration.

Electrical and Environmental Specifications

Natural air cooling eliminates the need for a cooling fan. The controller's operating environment and power requirements must be assessed at the assembled FCN-RTU system level, including the selected base module, power supply, and additional I/O modules where applicable. The manufacturer specifies IP20 protection for the FCN-RTU hardware, so enclosure protection must be considered separately when selecting an installation location.
