Omron CPH-X40DT1-D Compact PLC with MINT Operating System

The Omron CPH-X40DT1-D is a high-performance micro PLC featuring the MINT real-time operating system. It combines fast ladder logic execution with multitasking capabilities. The unit offers 40 built-in I/O points: 24 digital inputs (24V DC, sink/source) and 16 transistor outputs (PNP, 0.5A per channel). Designed for OEM machinery and standalone automation cells.

Processing and Memory

CPU speed: 120 MHz ARM Cortex. Program memory 64K steps, data memory 32K words. Execution time 0.02 µs for basic instructions. MINT OS supports cyclical tasks, event tasks, and interrupt tasks with priority levels. User programs can be written in ladder, structured text, or instruction list.

Integrated Features

Four high-speed counter inputs (max 100kHz) for encoder connection. Two pulse outputs (100kHz) for stepper drive positioning. Built-in RS-232C and RS-485 ports supporting Modbus RTU, Host Link, and no-protocol communication. Real-time clock with battery backup (calendar accuracy ±2 min/month).

Expansion and Networking

Expandable up to 128 I/O points using CP series expansion modules (digital, analog, temperature). An optional Ethernet port module (CP1W-CIF41) enables EtherNet/IP tag data links and FTP server. PLC can act as a Modbus TCP slave to SCADA. USB programming port for quick access to CX-Programmer.

Environmental Ratings

Power supply 24V DC, consumption 150mA without expansion. Operating temperature 0-55°C, humidity 10-90% non-condensing. IP20 enclosure, DIN rail or direct screw mounting. Vibration resistance 2g (10-57Hz). The I/O terminals are removable for easy replacement.

Applications

Used in packaging machinery, small assembly stations, conveyor control, and batch process automation. The built-in positioning outputs eliminate separate stepper controllers for single-axis motion. MINT OS allows deterministic response for time-critical tasks like registration mark cutting.

Programming and Diagnostics

Omron CX-Programmer (version 9.5 or later) supports CPH series. Online editing, data tracing, and forced I/O. The MINT kernel also supports C-function blocks for complex arithmetic. Internal diagnostics detect battery low, I/O bus error, and program mismatch.

Conclusion

The Omron CPH-X40DT1-D fills the gap between basic micro PLC and mid-range units. Its MINT RTOS provides predictable scan times, enabling precise control for hybrid motion/logic applications.
