Applications 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: v The TM4ES4 Ethernet switch module, offering an Ethernet connection with 4 ports v The TM4PDPS1 Profibus DP slave module b Ethernet switch module 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. v The TM4ES4 module is ready for use as soon as it is connected to the communication bus of M241 and M251 controllers. v This module is used to add the Ethernet function to TM241C24 p and TM241C40 p controllers without an embedded Ethernet port, while offering an additional Ethernet switch function. v Connected on controllers with embedded Ethernet port type TM241CE24 ppp or TM241CE40 ppp , it can constitute a second Ethernet link for the Machine or Factory network. v Connected on controllers with an embedded Ethernet port type TM241CE ppp or on a TM251MES p 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. b Slave Profibus DP module The TM4PDPS1 communication module can be used to configure a slave connection on the Profibus DP bus. Rules for combination Up to 3 communication modules (in total) can be added on the left of M241 and M251 logic controllers, in order to increase their options for connection to the Ethernet and Profibus networks. v TM241C24 ppp , TM241C40 ppp , TM241CE24 ppp and TM241CE40 ppp controllers can all be provided with a TM4ES4 module with the Ethernet port function and 2 TM4ES4 modules with the autonomous switch function while complying with the maximum number of 3 TM4 modules in total. v TM241CEC24 p and TM251 ppp controllers can be provided with 3 TM4ES4 modules with the autonomous switch function while complying with the maximum number of 3 TM4 modules in total. v TM4 communication modules are assembled by simply clipping them onto the left-hand side of M241 and M251 controllers, and a bus expansion connector is used to distribute data and power.
b TM4ES4 Ethernet switch module 1 Power on LED indicator. 2 Bus connector (1 on each side). 3 4 RJ 45 connectors for Ethernet network, with exchange and activity speed LED indicator. 4 Screw terminal for the functional ground (FG) connection. 5 Locking clip on 5 symmetrical rail. b TM4PDPS1 slave Profibus DP module 1 Power on LED indicator. 2 Bus connector (1 on each side). 3 9-way SUB-D connector for connection to the Profibus DP bus. 4 Screw terminal for the functional ground (FG) connection. 5 Locking clip on 5 symmetrical rail.
