Abstract

The embodiment of the invention discloses a controller inter-station communication method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a communication data structure table, and acquiring at least one piece of specified to-be-transmitted data in the communication data structure table; organizing the to-be-transmitted data according to a data structure specified in the communication data structure table to generate communication data; and sending the communication data to at least one second virtual controller by adopting a communication protocol specified by the communication data structure table so as to indicate each second virtual controller to respectively extract corresponding to-be-transmitted data from the communication data, wherein the first virtual controller and the second virtual controller independently run in different virtual execution environments. According to the embodiment of the invention, many-to-many datatransmission between the virtual controllers can be realized, the locking and synchronization requirements between the virtual controllers are met, and the cooperative control performance between thevirtual controllers is improved.

Description

technical field [0001] The embodiments of the present invention relate to the industrial field, and in particular, relate to a communication method, device, computer equipment, and storage medium between controller stations. Background technique [0002] In the industrial field, the control system needs to realize the coordinated control among multiple control stations. [0003] In the control system, the hardware functions of the controller can be virtualized to form a virtual controller, which can reduce the use and maintenance costs of physical devices. [0004] In a control system including virtual controllers, different virtual controllers are used to collect or generate different data respectively. Usually, a virtual controller needs to obtain the data collected or generated by other virtual controllers to realize the logic control of its own station, so as to realize the cooperative control among multiple virtual control stations. At present, there is no communicati...
