FUJI NPPS-32R High-Performance CPU Module

The FUJI NPPS-32R serves as the primary NPPS-32R High-Performance CPU Module utilized to execute cyclic scan processing, periodic task control, and event-driven logic execution across MICREX-SX SPH control platforms. The module features 20 ns instruction execution performance, integrated USB connectivity, built-in Flash ROM storage, and support for local and remote I/O architectures.

Hardware Specifications

Redundancy Architecture and I/O Density Scaling

The NPPS-32R supports both 1-to-1 hot standby and N-to-1 backup configurations within MICREX-SX SPH control systems. Redundant processor architectures allow control execution to continue through coordinated CPU synchronization and backup resource allocation.

The module supports direct SX Bus I/O expansion as well as distributed I/O architectures through DeviceNet, OPCN-1, and remote communication networks. Fixed-interval remote I/O refresh functions and synchronized local bus updates provide consistent data exchange between control logic and field devices.

Frequently Asked Questions

Q: What program capacity is available on the NPPS-32R?
A: The CPU supports a program memory capacity of 32K steps.

Q: Does the module support redundant controller configurations?
A: Yes. The module supports both 1-to-1 hot standby and N-to-1 backup system architectures.

Q: How long is memory retention supported by the backup battery?
A: The specified lithium battery provides approximately 5 years of backup operation at 25 deg C for data memory and calendar memory retention.

Field Installation Guidelines

• Isolate system power before installing or replacing the CPU module.

• Verify rack and firmware compatibility prior to commissioning.

• Ensure the module is fully seated in the backplane connector.

• Route communication cables separately from power wiring.

• Verify battery condition before placing the controller into service.

• Confirm I/O communication and CPU status after startup.
