Modbus multi-master-station data planning and forwarding device

The invention belongs to the field of modbus multiple master stations, and particularly relates to a modbus multiple master station data planning and forwarding device. Comprising an RS485 communication module which is used for accessing an original modbus RTU/ASCII communication link and accessing other master stations to a master station interface of the RS485 communication module; and the controller is used for finding out a communication interval in each period by monitoring the communication period of the original modbus RTU/ASCII communication link, allowing other added master stations to communicate in the interval, and realizing modbus RTU/ASCII multi-master-station communication through time-sharing communication. According to the invention, the problem that other devices are difficult to collect slave data due to the fact that only one host exists on the modbus is solved, and the use effect is remarkable. 本发明属于modbus多主站领域，具体说是一种modbus多主站数据规划和转发装置。包括：RS485通信模块，用于接入原有modbusRTU/ASCII通信链路中，并通过将其他主站接入自身主
