Using Anybus Communicator as external network interface for sensor and measurement applications

Sensor and measurement applications that do not have an integrated network interface, can easily be connected to fieldbus and industrial Ethernet networks via their RS-232 interface and the Anybus Communicator.

Flexible communication is a key successes factor for almost any sensor or measuring device. While complex sensors typically offer powerful integrated network interfaces, small and simple sensors often only support serial communication via RS-232/485 interfaces with Modbus or other proprietary protocols.  In these cases, the Anybus Communicator can be used as an external interface to integrate the Sensor into almost any fieldbus or industrial Ethernet network.


The Anybus Communicator is connected to the RS-232/485 interface of the sensor and translates the serial data stream into a fieldbus or industrial Ethernet protocol. The Communicator completely handles the protocol conversation and represents the sensor as a slave/adapter on the network.  For the central PLC (master / scanner) the sensor functions as a standard node on the network with slave functionality. As the Anybus Communicator is available for almost any industrial network, the sensor can be connected to many different networks with the same connectivity solution without additional development efforts.

For applications where several sensors are used, one Communicator can be used to connect up to 31 sensors to the industrial network. Prerequisite is, that the sensors provide an RS-422/RS-485 bus type interface. In this case, The cost of the network connection per sensor will be less than with an embedded solution. Read more
