FUJI NP1PU-128E MICREX-SX SPH3000 CPU Module

The FUJI NP1PU-128E is a CPU module for the MICREX-SX SPH3000 programmable control platform. Equipped with a 32-bit RISC processor, it provides 128k steps of program capacity and 1,024k words of data memory for control logic, data handling, and system communication tasks. The module also integrates Ethernet connectivity and SD card support for network access and data storage functions.

Processing and Memory Architecture

The NP1PU-128E utilizes a 32-bit RISC CPU designed for PLC execution and data processing. Its program memory capacity of 128k steps (131,072 steps, with 1 step equivalent to 2 words) supports large control applications and complex automation routines.

The module includes 1,024k words of data memory, providing substantial space for variables, process data, recipes, and communication buffers. In addition, the default M memory area offers 98,304 words for internal device allocation and control functions.

I/O Memory Resources

The available I/O memory consists of 512 words as standard and can be expanded up to 8,192 words depending on the system configuration. This memory area is used for exchanging data between the CPU and connected I/O modules within the control system.

The scalable I/O memory architecture allows the controller to accommodate projects with varying levels of field-device integration.

Programming Environment

The NP1PU-128E supports programming languages compliant with the IEC 61131-3 standard. Supported languages include:

• IL (Instruction List)

• ST (Structured Text)

• LD (Ladder Diagram)

Compliance with IEC 61131-3 enables consistent application development and simplifies software portability within standardized automation environments.

Communication and Storage

The module incorporates a built-in Ethernet interface for network communication and system integration. An integrated SD card slot provides removable storage for application data, backups, and maintenance-related functions.

These features allow engineers to manage programs and data without requiring external communication modules for basic Ethernet connectivity.

Technical Specifications

Application Considerations

The combination of a 32-bit RISC processor, large memory capacity, and built-in Ethernet connectivity makes the NP1PU-128E suitable for applications requiring extensive control logic and data handling. When specifying a replacement module, memory capacity, firmware compatibility, and system configuration should be verified against the installed MICREX-SX SPH3000 platform.

The integrated SD card slot can simplify maintenance procedures by supporting data transfer and application backup functions within compatible system environments.
