TM258LD42DR Schneider Electric Modicon M258 Compact Logic Controller
The TM258LD42DR belongs to the Schneider Electric Modicon M258 series. It is a compact logic controller with 42 I/O, mixed relay and transistor outputs, and a 24 VDC supply. A dual-core ARM Cortex-A8 processor separates program tasks and communication tasks. This design keeps control and network traffic stable under heavy load.
This controller fits machine control, production lines, and distributed automation. It offers Ethernet, CANopen, RS-485, and USB ports. Two free PCI slots accept communication or function modules. Up to seven TM5 or TM2 expansion modules can extend I/O to 2400 points.

Installation Guide
- Mount the controller on a DIN rail or panel. Keep IP20 protection in mind.
- Use a 24 VDC supply within 19.2 to 28.8 V.
- Allow airflow around the 99 × 265 × 75 mm housing.
- Keep high-voltage cables away from signal cables.
- Connect Ethernet, CANopen, RS-485, and USB before power-up.
- Use shielded cables for CANopen and RS-485.
- Check grounding to reduce noise on fast inputs and outputs.
Debugging and Maintenance
- Use SoMachine or EcoStruxure Machine Expert for online diagnostics.
- Check LED status for power, I/O, and communication faults.
- Monitor scan load with the built-in scan speed data.
- Back up programs and parameters before changes.
- Clean the housing with a dry cloth. Do not use solvents.
- Verify relay output life in high-cycle applications.
- Replace modules only after power is off.
