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

How the Communication Works

The Communicator enables communication, data exchange, between one or more server devices connected to a serial subnetwork and a client device connected to a high level network.

For example:

  • The client device can be a PLC controller or a PC.

  • A server devices can be a sensor, scanner, industrial robot or sniffer.

The Communicator main task is to cyclically send the transactions that the server(s) are configured to execute, in order to request and transfer process data.

Request Process Data

Request process data from the serial subnetwork nodes, specified in the Communicator configuration, and make the process data available on the server interface and for the high level network client device.

Transfer Process Data
