Schneider LMC078CECS20T Modicon LMC078 24VDC Sercos III CANopen Motion

Product Specification

Product Overview

The Schneider LMC078CECS20T is a legacy Modicon LMC078 logic and motion controller designed for high-performance machines requiring synchronized multi-axis motion, logic control and distributed I/O management.

The controller operates from a 24 VDC power supply and includes embedded-I/O positioning identified by the 20T code. It is associated with transistor-output architecture, although the exact digital input and output allocation and high-speed channel functions must be verified from the reference-specific documentation.

The LMC078CECS20T is positioned for machine systems using Sercos III motion communication, CANopen networks, Ethernet communication, serial devices and compatible TM5 or TM7 I/O platforms.

Technical Specifications

Compatible System and Applications

The LMC078CECS20T is suitable for packaging machinery, printing equipment, textile machines, converting lines, material-handling systems, coordinated conveyors and robotics-related machine equipment.

The Sercos III network may control compatible servo drives and synchronized motion devices. The CANopen network may include drives, remote I/O and auxiliary machine devices.

The embedded I/O can support machine signals and high-speed functions, but the exact channel allocation must be confirmed from the hardware documentation and original Control project.

Maintenance and Replacement Notes

Use only the complete LMC078CECS20T reference when preparing a quotation or replacement. Partial references such as LMC078 or LMC078CECS are not sufficient.

Before replacement, back up the SoMachine Motion project, controller firmware, libraries, memory-card data, Sercos III drive topology, CANopen node list, EDS files, Ethernet settings, serial configuration and complete TM5 or TM7 module arrangement.

Verify the original HMI project, machine-safety system, servo-drive firmware and network timing requirements. A controller replacement may require a complete controlled recommissioning procedure.

For used or refurbished equipment, perform powered testing, communication-port testing, memory verification, diagnostic review and controlled burn-in.

Related Models

LMC058LF42 and LMC058LF42S0 are related Modicon legacy motion controllers but use different commercial references, hardware positioning and project configurations.

ELAU PacDrive LMC controllers belong to another motion-control platform and are not direct replacements for LMC078CECS20T.

Inquiry and Supply Notes

Please provide a complete nameplate photograph, hardware revision, firmware version, SoMachine Motion project, memory-card status, Sercos III drive list, CANopen nodes, Ethernet settings, TM5 or TM7 modules and machine-safety architecture.

Embedded-I/O allocation, project compatibility, product condition, functional testing, regional availability and delivery time must be confirmed before quotation.
