Maximum Hardware Configuration

Introduction

The M251 Logic Controller is a control system that offers an scalable solution with optimized configurations and an expandable architecture.

Local and Remote Configuration Principle

The following figure defines the local and remote configurations:

 

(1)   Local configuration

(2)   Remote configuration

M251 Logic Controller Local Configuration Architecture

Optimized local configuration and flexibility are provided by the association of:

oTM4 expansion modules

oM251 Logic Controller

oTM3 expansion modules

oTM2 expansion modules

Application requirements determine the architecture of your M251 Logic Controller configuration.

The following figure represents the components of a local configuration:

 

(A)   Expansion modules (3 maximum)

(B)   Expansion modules (7 maximum)

NOTE: It is prohibited to mount a TM2 module before any TM3 module as indicated in the following figure:

 

 

M251 Logic Controller Remote Configuration Architecture

Optimized remote configuration and flexibility are provided by the association of:

oTM4 expansion modules

oM251 Logic Controller

oTM3 expansion modules

oTM3 transmitter and receiver modules

Application requirements determine the architecture of your M251 Logic Controller configuration.

NOTE: You cannot use TM2 modules in configurations that include the TM3 transmitter and receiver modules.

The following figure represents the components of a remote configuration:

 

(1)   Logic controller and modules

(C)   Expansion modules (7 maximum)

Maximum Number of Modules

The following table shows the maximum configuration supported:

NOTE: The configuration with its TM4, TM3, and TM2 expansion modules is validated by EcoStruxure Machine Expert software in the Configuration window.

NOTE: In some environments, the maximum configuration populated by high consummation modules, coupled with the maximum distance allowable between the TM3 transmitter and receiver modules, may present bus communication issues although the EcoStruxure Machine Expert software allows for the configuration. In such a case you will need to analyze the consummation of the modules chosen for your configuration, as well as the minimum cable distance required by your application, and possibly seek to optimize your choices.
