Overview

Schneider Electric Modicon TM4 Series - Flexible I/O Expansion Modules for Modicon M241 and M251 Series Controllers:

The Modicon TM4 communication module offer is dedicated to Modicon M241 and Modicon M251 logic controllers, increasing the options for connection. Two communication module models are available:
- The TM4ES4 Ethernet switch module, offering an Ethernet connection with 4 ports
- The TM4PDPS1 Profibus DP slave module

Modicon TM4 communication modules are assembled by simple interlocking on the left-hand side of the controllers and a bus expansion connector is used to distribute data and the power supply. Up to 3 communication modules can be added on the left of M251 logic controllers.

Features:

TM4 expansion modules are assembled by connecting them to a logic controller.

The logic controller and their expansion modules can be installed on a top hat section rail (DIN rail)

The TM4ES4 module is a 4-port Ethernet interface (10/100 Mbps, MDI/MDIX) with the following protocols: Ethernet Modbus TCP Client/Server, Ethernet/IP Adapter, UDP, TCP, SNMP, OPC UA Server and SoMachine.

The TM4ES4 module is ready for use as soon as it is connected to the communication bus of M241 and M251 controllers.

This module is used to add the Ethernet function to TM241C24p and TM241C40p controllers without an embedded Ethernet port, while offering an additional Ethernet switch function.

Connected on controllers with embedded Ethernet port type TM241CE24ppp or TM241CE40ppp, it can constitute a second Ethernet link for the “Machine” or “Factory” network.

Connected on controllers with an embedded Ethernet port type TM241CEppp or on a TM251MESp controller, it can also constitute an autonomous switch with four ports: communication between the TM4ES4 module and the Modicon M241 and M251 controllers is not automatically enabled by the bus connector

Ethernet switch module:style>
- The TM4ES4 module is a 4-port Ethernet interface (10/100 Mbps, MDI/MDIX) with the following protocols: Ethernet Modbus TCP (Client/Server), EtherNet/IP (Adapter/Originator), UDP, TCP, SNMP and SoMachine.
- Clipped onto the left-hand side of a Modicon M251 controller, it consists of an autonomous switch with 4 ports, supplied by the Modicon M251 controller.

Slave PROFIBUS DP module:
- The TM4PDPS1 communication module can be used to configure a Master connection on the PROFIBUS DP bus.
