The M262 Logic/Motion Controller is a control system that offers an all-in-one solution for motion applications and a scalable solution for logic applications, with optimised configurations and an open, expandable architecture. The M262 Logic/Motion Controller has various powerful features and can service a wide range of applications. Software configuration, programming, and commissioning are accomplished with the EcoStruxure Machine Expert software version 1.1. Maximum hardware configuration can be achieved as well as local and remote configurations.

Programming Languages - The M262 Logic/Motion Controller is configured and programmed with the EcoStruxure Machine Expert software, which supports the following IEC 61131-3 programming languages:
• IL: Instruction List
• ST: Structured Text
• FBD: Function Block Diagram
• SFC: Sequential Function Chart
• LD: Ladder Diagram
EcoStruxure Machine Expert software can also be used to program these controllers using CFC (Continuous Function Chart) language.
Power Supply - The power supply of the M262 Logic/Motion Controller is 24 Vdc
Real-Time Clock - The M262 Logic/Motion Controller includes a Real-Time Clock (RTC) system. The system time is maintained by capacitors when the power is off. The time is maintained for 1 000 hours when the controller is not supplied.
Run/Stop - The M262 Logic/Motion Controller can be operated externally by the following:
• A hardware Run/Stop switch
• A Run/Stop operation by a dedicated digital input, defined in the software configuration. For more information, refer to Configuration of Digital Inputs (see Modicon M262 Logic/Motion Controller, Programming Guide).
• An EcoStruxure Machine Expert software command
• The system variable PLC_W in a Relocation Table
• The Web server
Memory - Three different memory types - RAM, Flash and Non-volatile RAM which suits a variant of uses and comes in different sizes
Embedded Inputs/Output types - Fast inputs and fast source outputs
Encoder - Incremental and SSI encoder modes available
Removable Storage - The M262 Logic/Motion Controllers include an integrated SD card slot. The main uses of the SD card are:
• Initializing the controller with a new application
• Updating the controller and expansion module firmware
• Applying post configuration files to the controller
• Storing recipes, files
• Receiving data logging files
Embedded Communication Features - The Modicon M262 range features embedded communication features, it has Ethernet, USB Mini-B, Serial Line and Sercos communication ports available.

A PLC (programmable logic controller) is an industrial digital computer designed for the control of manufacturing processes or robotic devices where reliability control, simple programming and fault diagnosis is necessary. They were originally built to replace electromechanical relay systems in industrial automation.
A CPU (central processing unit) forms part of the PLC system. PLC CPUs are microprocessor-based and act as the electronic circuitry within an industrial computer. They carry out instructions from the computer program, performing basic mathematical, logical, control, input and output operations.
