Modbus Protocol:

Modbus Protocol is a serial communications protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs). Simple and robust, it has since become a de facto standard communication protocol, and it is now a commonly available means of connecting industrial electronic devices.

Utthunga has vast experience with Modbus protocol and provided a various solution using this protocols to its customers.
