The industrial control network system provided by the present invention is applied in the technical field of industrial control. The system includes at least one main control module and at least one IO module. The main control module includes a main controller and a TSN communication module. The IO module includes a TSN transmission module and at least one An IO interface. The main controller is connected to the TSN communication module, the TSN transmission module is connected to each IO interface, and the TSN communication module in each main control module is connected to the TSN transmission module in each IO module to form an industrial control network system. In the system, the network data transmission between the TSN transmission module and the TSN communication module is based on the TSN protocol, and the main controller executes the preset control function based on the obtained network data. On the premise of realizing the preset control function of the industrial control network system, using TSN The network protocol can accurately transmit the characteristics of network data, improve the data transmission performance of the industrial control network system, and thus meet the requirements for the timeliness of data transmission.
Description
technical field [0001] The invention belongs to the technical field of industrial control, in particular to an industrial control network system. Background technique [0002] In most application scenarios of industrial control, the transmission performance of the control network is extremely high, not only limited to the requirements for jitter and delay in the network data transmission process, but also requires that the network data can be transmitted at a highly deterministic and predictable time. Click Delivered. [0003] Most of the current industrial control network systems are based on the standard Ethernet, through the improvement of the standard Ethernet communication protocol, and at the same time cooperate with hard real-time or soft real-time technical means to realize the transmission of network data. Since the standard Ethernet is essentially a non-deterministic transmission network, the delay in the network data transmission process cannot be effectively gua...
