R035 RS485 / Ethernet converter, Modbus router
Same as M031, firmware extended by Modbus RTU / TCP routing functionality. Supply 24 V DC / AC ± 10 %. DIN rail mounting, dimensions 98,7 x 64 x 36,2 mm
R035 is a 10/100 Mbit Ethernet to RS485 converter, also called “terminal server”. It is configurable as Modbus RTU/TCP router. This converter is a successor of the previous type M035.
- remote Modbus RTU/RS485 device to SCADA Modbus TCP connection via an Ethernet network
- connection of domat I/O modules for data transmission and signal readout
- the usage depends on the communication protocol at the RS485; in some situations the Ethernet delays may not meet the timing requirements of the serial protocol driver
Function The R035 module contains all the features of the R031 module. It is able to connect a RS485 device to a PC over an Ethernet network. The Digi RealPort Software creates a virtual COM port on the host PC. This virtual port enables any software to communicate with a remote RS485 device. The COM port redirector runs under Microsoft Windows, UNIX and Linux. Maximum communication speed is 115200 bps.
The main difference between R030 and R035 is the industrial automation profile selection option for R035. This is the Modbus RTU/TCP router functionality. On the TCP side the module acts as slave (server) and sends the requests as master (client) to the serial line with Modbus RTU.
The module parameters and functions are configured over SNMP or secured web communication (HTTP / HTTPS protocols). Power presence is indicated by a green LED close to the serial connector. The Ethernet connector provides two LEDs: Link

and Network activity. The network switches automatically between 10 and 100 Mbit/s.
To connect the RS485 bus there are 2 screw terminals. The RS485 data flow is indicated by LEDs: TxD (green) and RxD (red). The RS485 bus may be terminated by a pair of DIP switches (close to the RS485 terminals). Communication speed and number of data bits are set by DIP switches (the right of the RS485 terminals). The RS485 bus is galvanically isolated (insulation voltage 1000 V).
The module is 36,2 mm wide and mounts on a standard DIN rail.
