Why the LMC058LF424 Still Matters on the Factory Floor
Machine builders who standardized on the Modicon LMC058 platform know the dilemma: the LMC058LF424 delivers 4 synchronized axes and 42 I/O points in one compact controller, but Schneider Electric has announced its discontinuation. This guide explains what the controller does, how to keep existing machines running, and when to plan a migration to the Modicon M262.
What Is the Schneider LMC058LF424?
The LMC058LF424 is a motion controller from the Modicon LMC058 series. It combines a dual-core ARM Cortex-A8 processor with 128 MB Flash program memory and 64 MB RAM. A scan speed of 22 ns per Boolean instruction keeps logic execution fast enough for coordinated motion tasks.
The controller manages 4 synchronized axes through CANmotion, while CANopen master support handles standard drives and remote I/O. Built-in Ethernet, serial, and dual CAN ports cover most machine architectures without extra communication cards.

LMC058LF424 vs. Comparable Controllers
| Criterion | LMC058LF424 | Typical PLC + separate motion module |
|---|---|---|
| Axes | 4 synchronized (CANmotion) | Depends on module count |
| I/O onboard | 42 points | Usually fewer onboard |
| Scan speed | 22 ns per Boolean instruction | Varies by CPU |
| Footprint | 175 × 99 × 85 mm | Larger with extra modules |
| Lifecycle | Discontinued 2026-06-30 | Varies |
A combined controller reduces cabinet space and wiring compared with a separate PLC and motion module. That integration is exactly why many OEMs still run this platform.
Where It Fits in Real Machines
Packaging lines. Four synchronized axes handle film feed, sealing, and cut-off motions. The 10 fast digital inputs capture registration marks, while 4 fast outputs drive high-speed valves or triggers.
Material handling. CANopen master support connects drives and remote I/O over one bus. The 26 digital inputs absorb sensors across a conveyor section without immediate expansion.
Retrofit projects. Because the unit mounts on a symmetrical DIN rail and measures only 175 × 99 × 85 mm, it drops into existing cabinets with minimal rework.
Installation and Setup Notes
Mount the controller on a symmetrical DIN rail inside an enclosure rated for the environment. The IP20 rating means the unit needs protection from dust and moisture. Feed the main supply with 24 V DC within the 20.4…28.8 V range, and account for a rated main supply current of 0.28 A.
A 3 V CR2477M lithium battery maintains the real-time clock and data retention. Replace it during scheduled maintenance to avoid losing retention data.
Program the controller with SoMachine or EcoStruxure Machine Expert. The built-in USB-B mini port handles programming, while the USB-A port accepts a memory stick for file transfer.
Maintenance and Lifecycle Planning
Keep the cabinet within the 0…+55 °C operating range and avoid condensing humidity beyond 95%. Inspect the battery, DIN rail fixation, and connector seating at regular intervals.
Lifecycle status deserves attention. Schneider Electric discontinued this model on 2026-06-30, with end-of-service on 2031-06-30. Machines still running the LMC058LF424 will need spare units or a planned migration. Schneider points to the Modicon M262 as a replacement path. Verify current lifecycle status and availability with SpareTechPLC before ordering.
Compatibility and Integration
Built-in ports cover 1× Ethernet RJ45 (10/100BASE-TX), 1× serial RS-232/RS-485, 2× CAN (SUB-D9), 1× encoder input (SUB-D15), 1× USB-B mini, and 1× USB-A. Supported protocols include Modbus TCP/IP, Modbus RTU/ASCII, CANopen master, and CANmotion master. Communication expansion options include EtherNet/IP, SERCOS III, and optional PCI communication modules.
What to Verify Before Buying
Confirm your axis count, I/O requirements, and protocol mix against the data above. Check whether your application needs analog signals — this model has none, so analog points require separate hardware. Confirm the battery type and programming software version your team uses. SpareTechPLC supplies industrial automation parts and can help you match the right configuration.
Frequently Asked Questions
Is the LMC058LF424 discontinued?
Yes. Schneider Electric lists a discontinuation date of 2026-06-30 and an end-of-service date of 2031-06-30. Plan spare stock or migration accordingly.
How many axes can the LMC058LF424 control?
It controls 4 synchronized axes through CANmotion, with CANopen master support for additional devices.
Does the LMC058LF424 have analog inputs or outputs?
No. The controller provides digital I/O only, so analog signals need separate modules.
What software programs the LMC058LF424?
Use SoMachine or EcoStruxure Machine Expert.
What replaces the LMC058LF424?
Schneider Electric points to the Modicon M262 as a replacement path. Contact SpareTechPLC to discuss availability and migration options.
