RS-485/Ethernet interface converter

The RS-485/Ethernet interface converter (UI) is designed to combine various types of Modbus devices into a single network.

Data transfer between devices takes place using a standard protocol ModbusTCP (from the Ethernet side) and ModbusRTU (from the RS-485). Support of these protocols by many SCADA packages expands the possibilities of building industrial automation systems. The result is a very simple and efficient way to connect different devices to a PC or PLC on an Ethernet network.
The converter supports up to 10 TCP sockets. This means that on an Ethernet network, up to 10 devices can communicate with the inverter at any given time.

The interface converter ModBus RS-485 / Ethernet has the ability to separate the RS-485 network (ModbusRTU) into several smaller ones, with a separate PI RS-485 / Ethernet converter, each of which will be connected to one Ethernet network. Consequently, many more devices can be combined. If there is a connection to the global Internet network, it becomes possible to access and control the connected equipment from any place that has an Internet connection.
This converter, which is connected to an Ethernet network, provides a much higher bandwidth than individual RS-485 networks, and this in turn increases the frequency of polling the instrument parameters.

The instrument is configured via the web-interface, which can be accessed using any standard web browser, e.g. Internet Explorer.
Each inverter Modbus TCPThe /RTU has a unique Ethernet IP address, which must be specified on the PC or PLC when configuring the system to be connected.
