Abstract
A communication method and a communication device based on a parallel system, a terminal and a computer readable storage medium are provided. The parallel system includes a fieldbus and two or more communication nodes connected to the fieldbus in parallel. The communication method includes: acquiring a status parameter of a target communication node; converting the status parameter into a logic level signal; generating an input differential signal based on the logic level signal; sending the input differential signal to the fieldbus and synchronously receiving an output differential signal from the fieldbus, where the output differential signal is generated by the fieldbus by performing a wired-AND operation on input differential signals received from the two or more communication nodes; and acquiring information of the communication nodes connected to the fieldbus based on the output differential signal.
