There are 2 communication module models available: v The TM4ES4 Ethernet switch module providing a 4-port Ethernet connection 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 Ethernet Modbus TCP (Client/Server), Ethernet/IP (adapter), UDP, TCP, SNMP, and SoMachine protocols. 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 Ethernet functionality to TM241C24 p and TM241C40 p controllers without embedded Ethernet port while offering the additional functionality of an Ethernet switch. v When connected to TM241CE24 ppp or TM241CE40 ppp type logic controllers with embedded Ethernet port, it acts as a second Ethernet link for the Machine or Factory link. v When connected to TM241CE ppp type controllers with embedded Ethernet port, or to a TM251MES p controller, it can also act as a standalone 4-port switch: communication between the TM4ES4 module and Modicon M241 and M251 controllers does not occur automatically via the bus connector. b Profibus DP slave module The TM4PDPS1 communication module is used to configure a slave connection on the Profibus DP bus. Combination rules A maximum of 3 communication modules can be added on the left-hand side of M241 and M251 logic controllers in order to increase their connectivity to the Ethernet and Profibus networks. v On TM241C24 ppp , TM241C40 ppp , TM241CE24 ppp , and TM241CE40 ppp controllers, it is possible to add a TM4ES4 module with Ethernet port function and 2 TM4ES4 modules with the standalone switch function while respecting the maximum number of 3 TM4 modules. v On TM241CEC24 p and TM251 ppp modules, it is possible to add 3 TM4ES4 modules with the standalone switch function while respecting the maximum number of 3 TM4 modules. v TM4 communication modules are assembled by simply clipping them onto the left-hand side of M241 and M251 logic controllers; a bus expansion connector is used to distribute data and power.
