The Hitachi LPU100H is the central nervous system of the HIDIC-S10 control system. Designed to handle large-scale automation tasks, it features a high-performance processor optimized for boolean logic, floating-point math, and complex PID control loops. The LPU100H ensures that even the most demanding industrial processes are controlled with microsecond precision.
Equipped with robust internal memory, the LPU100H can store extensive user programs and large data registers. It utilizes Error Correction Code (ECC) memory to prevent bit-flips and data corruption, a feature usually reserved for high-end servers but implemented here to ensure industrial safety. The module also supports battery-backed RAM to preserve critical process data during power outages.

The LPU100H is not just a processor; it is a communication hub. It manages the data flow across the backplane to I/O modules and supports peer-to-peer networking with other LPU modules. This allows for the creation of distributed control architectures where multiple LPU100H units work in tandem to manage an entire factory floor.
For applications where downtime is unacceptable, the LPU100H can be configured in a redundant "Hot Standby" mode. In this setup, two LPU100H modules run the same program simultaneously; if the primary unit detects an internal fault, the secondary unit takes control instantly without interrupting the process. This level of availability is why Hitachi remains a leader in heavy industry automation.
Engineers program the LPU100H using Hitachi’s dedicated software suite, which supports ladder logic and high-level languages. The module features a dedicated programming port for local access, as well as network-based configuration options. Its firmware is designed to be stable and resilient, providing a "set and forget" experience for system integrators.
