7. A module information acquisition method of an industrial control system is characterized by comprising the following steps:
sending a preset reading data packet for reading module information to a communication unit of the industrial control system so that the communication unit feeds back corresponding first module information according to the reading data packet;
controlling the communication unit to forward the read data packet to a controller so that the controller feeds back corresponding second module information according to the read data packet;
and after the IO module sends the third module information of the IO module to the controller, sending the read data packet to the controller so that the controller feeds back the third module information according to the read data packet.
8. The method according to claim 7, wherein the process of the IO module sending the third module information of the IO module to the controller specifically includes:
the IO module sends the third module information of the IO module to an IO master station;
and the controller and the IO master station realize data interaction through a double-port RAM (random access memory), and acquire the third module information of the IO module.
9. A module information acquisition device of an industrial control system, comprising:
the system comprises a first acquisition module, a second acquisition module and a communication unit, wherein the first acquisition module is used for sending a preset reading data packet for reading module information to the communication unit of the industrial control system so that the communication unit feeds back corresponding first module information according to the reading data packet;
the second acquisition module is used for controlling the communication unit to forward the read data packet to the controller so that the controller can feed back corresponding second module information according to the read data packet;
and the third acquisition module is used for sending the read data packet to the controller after the IO module sends the third module information of the IO module to the controller, so that the controller feeds back the third module information according to the read data packet.
10. An industrial control system is characterized by comprising a module information setting device and a module information acquisition device;
the module information setting device is used for sending a preset setting data packet for setting module information to a communication unit of the industrial control system, so that the communication unit can set corresponding first module information according to the setting data packet; controlling the communication unit to forward the setting data packet to a controller so that the controller sets corresponding second module information according to the setting data packet; calling configuration software by using the controller to acquire third module information, and setting the corresponding third module information for the IO module;
the module information acquisition device is used for sending a preset reading data packet for reading module information to a communication unit of the industrial control system so that the communication unit feeds back corresponding first module information according to the reading data packet; controlling the communication unit to forward the read data packet to a controller so that the controller feeds back corresponding second module information according to the read data packet; and after the IO module sends the third module information of the IO module to the controller, sending the read data packet to the controller so that the controller feeds back the third module information according to the read data packet.
