Information translation device, method, system and computer readable recording medium based on modbus

An information translation method based on Modbus adapted to receive a Modbus data through a Modbus protocol and transmit the translated Modbus data to an open platform communication unified architecture device through an open platform communication unified architecture (OPC UA) protocol, wherein the information translation method comprises:

• receiving an information model file by a client module, wherein the information model file comprises identity information;
• receiving a sensor signal corresponding to first identity information and the Modbus data by the client module, wherein the Modbus data comprises a plurality of memory addresses of the Modbus protocol;
• determining a first memory address of the plurality of memory addresses corresponding to the sensor signal by the client module according to the plurality of sensed values of the sensor signal and the plurality of values corresponding to each of the memory addresses, and building a memory address mapping table comprising the first memory address and the first identity information;
• receiving a first value of the first memory address and searching the first identity information corresponding to the first memory address according to the memory address mapping table by the client module;
• and
• receiving the first value and the first identity information and transmitting the first value and the first identity information to the open platform communication unified architecture device by a server module.
