HITACHI CPM-E3 – High-Performance CPU Module | H Series PLC Platform
Engineering Background
The HITACHI CPM-E3 is a central processing unit module designed for the Hitachi H Series programmable logic controller platform — one of Japan’s most established industrial automation architectures. Built to meet the rigorous demands of continuous process control, discrete manufacturing, and infrastructure automation, the CPM-E3 delivers deterministic scan-cycle performance in environments where reliability is non-negotiable.
Product Positioning
Targeted at procurement engineers and systems integrators sourcing replacement or expansion CPU modules for existing Hitachi H Series installations, the CPM-E3 occupies the mid-range tier of the H Series CPU lineup. It balances program memory capacity, I/O expansion capability, and communication flexibility — making it the preferred choice for mid-complexity machine control and process automation projects.

System Architecture & Signal Flow
The CPM-E3 installs into the CPU slot of an H Series base unit or expansion rack. The CPU executes the user ladder program cyclically, reading input image data from all connected I/O modules at the start of each scan, processing logic, and writing output image data at the end of each scan. Communication with HMI panels, SCADA systems, or peer PLCs is handled via the onboard serial ports using Hitachi’s H Series communication protocol or standard Modbus RTU.
Program development and online monitoring are performed via Hitachi’s dedicated programming software connected through the RS-232C programming port. The CPM-E3 supports online program editing and forced I/O operations for commissioning and maintenance workflows.

Technical FAQ
Q: Is the CPM-E3 compatible with all H Series base units?
A: The CPM-E3 is designed for the Hitachi H Series platform. Compatibility depends on the specific base unit model and firmware revision. Contact Konmask with your existing rack model for confirmation.
Q: Can the CPM-E3 communicate with third-party HMI panels?
A: Yes. The onboard RS-232C/RS-485 ports support Modbus RTU, enabling integration with most major HMI brands including Weintek, Proface, and Siemens TP series.
Q: What programming software is required?
A: Hitachi’s H Series ladder logic programming software (e.g., Hitachi Ladder Editor) is required. Contact Konmask if you need assistance sourcing the software or cables.
Q: Do you offer volume pricing for OEM or system integrator orders?
A: Yes. Volume discounts are available for orders of 5+ units. Submit your BOM or project requirement to support@konmask.com for a project quotation.
Q: What is the warranty on this module?
A: Konmask provides a 30-day DOA (Dead on Arrival) guarantee. Extended warranty options are available upon request for large-volume orders.
