Use this overview of the DATA_EXCH function block to configure both EtherNet/IP and Modbus TCP explicit messages.

These instructions describe the configuration of the DATA_EXCH function block’s management parameter, which is common to both Modbus TCP and EtherNet/IP explicit messaging.

In a Hot Standby system, the primary BMENOC0301/11 Ethernet communication module sends the explicit message. Even when a switchover occurs and the primary becomes the standby, the module can run the active sections.
