TM4 Expansion Modules Compatibility
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:
oExpansion: 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.
oStandalone: Ethernet switch (only getting its power supply from the controller).
The table shows the TM4ES4 Ethernet module compatibility with controllers:
