Network characteristics of Modicon M241 and M251 controllers

Topology Daisy chain and star with use of switches Bandwidth 10/100 Mbps EtherNet/IP Scanner performance Up to 16 slave devices managed by the controller in 10 ms Ethernet Modbus TCP Scanner performance Up to 64 slave devices managed by the controller in 64 ms Note: When EtherNet/IP and Modbus TCP devices are controlled simultaneously on the same network, 16 devices maximum can be controlled (EtherNet/IP + Modbus TCP).

Ethernet ports on logic controllers and the Ethernet switch module

M221 logic controllers 1 On TM221ME pppp controllers: RJ 45 connector for Ethernet network, with exchange and activity speed LED indicator. 2 On TM221CE ppp controllers: RJ 45 connector for Ethernet network, with exchange and activity speed LED indicator. M241 logic controllers 3 On TM241CE ppp controllers: RJ 45 connector for Ethernet network, with exchange and activity speed LED indicator. M251 logic controllers 4 On TM251MESE and TM251MESC controllers: 2 connectors connected by an RJ 45 internal switch for Machine or Factory Ethernet network, with exchange and activity speed LED indicator. 5 On TM251MESE controller: RJ 45 connector for fieldbus Ethernet network with exchange and activity speed LED indicator. This port can be used with the Industrial Ethernet Manager function. TM4ES4 Ethernet switch communication module 6 4 RJ 45 connectors for Ethernet network with exchange and activity speed LED indicator.
