TM4 Expansion Modules Compatibility

Introduction

This section describes the compatibility of TM4 expansion modules with controllers.

The TM4 bus supports up to 3 expansion modules. You can mix both Profibus DP (TM4PDPS1) and Ethernet (TM4ES4) expansion modules to the limit of 3 expansions.

TM4ES4 Ethernet Module Compatibility

The TM4ES4 module has 2 applications:

  • Expansion: addition of an Ethernet interface to extend the number of Ethernet ports for a controller,

    NOTE: If more than 1 TM4ES4 module is installed on the controller, the one closest to the controller is used as expansion.

  • Standalone: Ethernet switch (only getting its power supply from the controller).

The table shows the TM4ES4 Ethernet module compatibility with controllers:
