New Modbus TCP RTU bridge enables power supplies to be controlled over the internet
PSU manufacturer VxI Power has developed a new bridge device that allows power supplies with Modbus RTU communications capability to be controlled and monitored over the internet or any other WAN or LAN.
As well as acting as a communication bridge between the Modbus RTU and Modbus TCP protocols, the IPM01 device features an embedded HTTP server that enables the user to view and configure PSU parameters via a web browser.
The device incorporates an RJ45 Ethernet socket and a 3-wire serial interface for either RS232 or RS485 communications - the latter capable of supporting multiple RTU clients. Both versions can deliver baud rates of up to 57600, and LED indicators are provided for seria...
