Anybus^® Communicator^™ - EtherNet/IP^™ to Modbus RTU/Serial

Figure 66. EtherNet/IP page, Connection settings

When the EtherNet/IP Client (PLC) opens a connection to the Communicator, it specifies an I/O data size.

By default the Communicator is set to Accept Only Matching I/O Sizes.

The connections must match the I/O size configured on the EtherNet/IP page, refer to To Use Automatic I/O Sizes and To Configure I/O Sizes Manually.

You can change to Accept All Connections.

The Communicator will accept all connections with an I/O size that is equal to or smaller than the configured I/O size in the Communicator.
