Two communication module models are available: v The TM4ES4 Ethernet switch module (offering, only on controllers without embedded Ethernet, 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: Modbus TCP (Client/Server), Ethernet IP (adapter), UDP, TCP, SNMP and SoMachine. v The TM4ES4 module is ready for use as soon as it is connected to the communication bus of M241 controllers. v This module is used to add the Ethernet function to TM241C24 p and TM241C40 p controllers without embedded Ethernet port while offering the additional functionality of an Ethernet switch. v When connected to logic controllers with embedded Ethernet port type TM241CE24 ppp , TM241CE40 ppp , or on a TM251M E S p controller it is a 4 port stand-alone switch: the communication between the TM4ES4 module and the Modicon M241 and M251 controllers is not done automatically by the bus connector. b Profibus DP slave module The TM4PDPS1 communication module can be used to configure a slave connection on the Profibus DP bus. Association rules Up to 3 communication modules (total) can be added on the left of M241 and M251 logic controllers, in order to increase their possibilities of connection to the Ethernet and Profibus networks. v On controllers without embedded Ethernet port (TM241C24 ppp and TM241C40 ppp ): it is possible to add one TM4ES4 module with the Ethernet port function and two TM4ES4 modules with the switch function while respecting the maximum number of 3 TM4 modules . v On controllers with embedded Ethernet port (TM241CE pp and TM251 ppp ): it is possible to add 3 modules TM4ES4 with switch function while respecting the number of 3 TM4 modules. v 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.
