RF Innovations has released the RFI-ESM Ethernet Serial Module that enables Ethernet TCP/IP communications over a SCADA radio network. The module transparently transfers all protocols at the Ethernet MAC layer including FTP and industry standard SCADA radio protocols such as TCP/IP Modbus and DNP protocols.
The RFI-ESM is suited for applications in utilities, mining, agriculture and transport industries, where reliable wide area Ethernet data transfer is critical. The module can be used in small and large scale systems offering the convenience of Ethernet and the wide area coverage of traditional SCADA radio systems.
The RFI-ESM transparently moves data from end-to-end at speeds of up to 115 kbps and when used with RF Innovations SCADA radio modems can transport Ethernet TCP/IP data over 30km. The RFI-ESM can also be used as a serial device server to provide an RS232 interface on a TCP/IP port. This effectively allows connection of RS232 devices on to an Ethernet network. When used with RF Innovations SCADA radios existing Ethernet infrastructure can be utilised as a backbone to provide connectivity to remote RS232 devices.
