Modbus is a well-known serial protocol, and the industrial automation market offers a wide range of devices with a Modbus interface, such as temperature sensors, barcode readers, motor controllers, and measuring instruments. Using the Anybus Communicator, all these devices can be easily integrated into modern automation systems based on Profibus and PLCs, such as those from Siemens, Schneider, and ABB.
The Anybus Communicator from HMS Industrial Networks is a small, self-contained device that mounts on a DIN rail. It is powered by a 24V industrial power supply and has a typical current consumption of only 100mA. On the Profibus side, the Communicator acts as a slave, and on the Modbus side, it acts as a master, supporting all data transmission rates from 1200 baud up to 56 kbit/s. In RS-485 mode, the product can connect up to 31 Modbus serial devices to Profibus and also supports Modbus-RTU and the Modbus-ASCII protocol. Configuration is completed in 7 simple steps using an easy-to-use Windows-based configuration tool.
The Profibus converter is part of the HMS Anybus Communicator family, which comprises 14 different versions supporting fieldbus systems such as Profibus, DeviceNet, ControlNet, CANopen, Interbus, FIPIO, Modbus-RTU, Modbus-Plus, CC-Link, and LonWorks, as well as industrial Ethernet protocols like EtherNet/IP, Profinet, Modbus-TCP, and EtherCAT. All versions provide the same functionality, enabling device manufacturers to connect their automation devices to all major industrial networks.
