Anybus Communicator Serial to PROFIBUS (AB7000)


Integrate your serial RS-232/422/485 based industrial devices and equipment, most commonly MODBUS RTU, to a PROFIBUS control system without the need for any changes to the device.


The Anybus Communicator - PROFIBUS (AB7000) is a proven and trusted protocol converter gateway that connects non-networked industrial devices and equipment to PROFIBUS.

The Communicator is capable of converting almost any type of serial protocol such as Modbus RTU, ASCII, DF1 or any other type of proprietary Query/Response or Produce/Consume protocol.


The gateway performs intelligent protocol conversion and presents the serial data to the Master PLC/Controller as easily processed I/O data.


The Communicator is a slim stand-alone gateway designed for IP20 and DIN-rail mounting, requiring a 24-volt power supply.



Typical serial applications include variable frequency drives, sensors, actuators, human machine interfaces, barcode readers, RFID readers and industrial scales among others.



Features and benefits

Saves machine builders and device manufacturers of integrating a PROFIBUS interface.

Allows system integrators to retro-fit older automation devices into modern PROFIBUS communication structures.

Requires no hardware or software changes to be made to the connected device.

Compatible with all PLCs with PROFIBUS support.

Performs complete serial protocol conversion, no PLC function blocks required.

Intelligent I/O data mapping within the Communicator permits even devices with slow serial communication can be integrated without any restrictions to the upper network.

Possibility to connect up to 31 nodes via one Communicator giving inexpensive PROFIBUS network connectivity for your devices.
