M218 System Architecture

Introduction

The M218 system is a compact control system that offers an all-in-one solution with optimized configurations and an expandable architecture.

Architecture Example

The following illustration provides an example of a Modicon M218 Logic Controller in a hardware environment:

 

 

M218 System Architecture

Optimized configurations and flexibility are provided by the association of:

oTM2...N I/O expansion modules

oAn accessory TM2DOCKN adaptor module to connect TM2 and TM3 I/O expansion modules

oTM2 digital I/O expansion modules

oTM2 analog I/O expansion modules

oTM3 digital I/O expansion modules

oTM3 analog I/O expansion modules

oTM3R mixed I/O expansion modules

Application requirements determine the architecture of your M218 system.

The illustration below shows the components of the M218 system:

 

1   M218 controller

2   TM2...N expansion I/O module

3   TM2 adaptor module TM2DOCKN

4   TM2 digital or analog expansion module

5   TM3 digital or analog expansion modules

NOTE: With M218 controller, it is not required to place a TM2 module before a TM3 module. The position of modules TM2 and TM3 can be mixed after the TM2DOCKN adaptor module
