About the Modicon M218 Logic Controller

Modicon M218 Logic Controller Devices Overview

Overview

The Schneider Electric Modicon M218 Logic Controller has a variety of powerful features. This Controller can service a wide range of applications.

The software configuration and programming is accomplished with the EcoStruxure Machine Expert software, and is described in the EcoStruxure Machine Expert Programming Guide.

Key Features

Programming languages

The Modicon M218 Logic Controller is supported and programmed with the EcoStruxure Machine Expert software, which supports the following IEC61131-3 programming languages:

oIL: Instruction List

oST: Structured Text

oFBD: Function Block Diagram

oSFC: Sequential Function Chart

oLD: 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 Modicon M218 Logic Controller is either: 24 Vdc or 100...240 Vac, depending on the controller model.

Real Time Clock

The Modicon M218 Logic Controller includes a Real Time Clock (RTC) system.

Run/Stop Switch

1 Run/Stop switch is integrated on each controller to toggle its state.

Memory

The table below describes the different types of memory:

Memory type	Size	Used
RAM	1 Mbytes	To execute the application.
Flash	1 Mbytes	To save program and data in case of a power interruption.

Embedded Input/Output

The following embedded I/O types are available, depending on the controller model:

oRegular input

oFast input (HSC)

oRegular output

oFast output (PTO/PWM/FG)

oAnalog input

oAnalog output

Embedded Communication features

3 types of communication ports are available on the front panel, depending on the controller model:

oEthernet Port (for TM218LDAE24DRHN and TM218LDAE40DRPHN)

oUSB Programming Port

o2 Serial Link Port

For more details, refer to the chapter Integrated Communication Ports.

(1) The reduced fast inputs have a maximum frequency of 10 kHz. They can be used either as regular inputs or as reduced fast inputs for counting. (2) The fast inputs can be used either as regular inputs or as fast inputs for counting or event functions. (3) The fast outputs can be used either as regular outputs or as fast outputs for PTO, PWM, Frequency Generator functions, or reflex output for HSC.
