[0039] Before describing the hardware architecture of a control system according to the present application, some specific terms are first explained:

[0040] Control system: a control system based on computer technology, communication technology and control technology, which can realize the functions of collecting signal data of production equipment, operating control logic, and controlling production equipment through signals.

[0041] Configuration data: in order to realize data collection and control of production equipment, the control system needs to pre-set analog data of production equipment, write control logic programs and other pre-set data, which are called configuration data.

[0042] Function block: also known as Function Block, a way to define control logic inside a control system, which can define control logic in a graphical way, and the control system can operate these corresponding logics and further process them.

[0043] Operation domain: composed of multiple computer hosts, including domain server roles and ordinary operation station roles, which supports configuration management of control system logic data, and allows operators to control the control system through operation stations during monitoring and operation;

[0044] Control domain: contains multiple controllers, which are distinguished by network addresses to distinguish the ownership and scope of the controllers, and support interconnection within the same control domain.

[0045] Controller: a hardware device in an industrial control system used to run pre-set sequential computing instructions and control field devices, which supports input signals from the field and feedback of computed signals to field output signals, and controls field devices through output signals;

[0046] Connection module: a connection component on the controller for connecting the controller and the rack;

[0049] Channel: The data channel inside the IO module. Each channel represents a logical bit and can receive input data or output data.

[0050] Based on the above explanation, the technical solution of the present invention will be described in detail below.

[0051] Example 1

[0052] like Figure 1 The diagram shown is a flowchart illustrating a hardware architecture demonstration method for a control system according to this embodiment, including the following steps:

[0053] S1: Obtain the configuration data of the control system;

[0054] S2: Organize data based on configuration data to form a corresponding data structure;

[0055] S3: Draw the hardware architecture based on the data structure; the hardware structure shows the logical relationship between the hardware and software structures contained in the hardware architecture in a hierarchical structure; expand the controller according to the hierarchical relationship between the connection relationship between the internal hardware structures of the controller and the data association relationship between the internal functional blocks of the controller.

[0056] Perform step S1 to obtain the configuration data of the control system.

[0057] The acquired data mainly includes hardware architecture-related data from the device's control system configuration data, primarily comprising four types of configuration data:

[0058] Data relationships within the operational domain, such as Figure 2 As shown, the operation domain mainly includes host node data, which can be divided into domain server type and operator station type. Furthermore, due to redundancy factors, two computers may be configured for the domain server. Therefore, the data in the operation domain can consist of the operation domain name and the list of host nodes attached to it.

[0059] Controller data relationships within the control domain, such as Figure 3 As shown, similar to the operational domain data, the control domain mainly consists of a list of controllers, and therefore can be defined as the control domain name and the list of controllers to which it belongs.

[0060] The hardware structure and functional block relationships within the controller, such as...Figure 4 As shown, the hardware data in the controller can be hierarchically decomposed according to the affiliation relationship: controller -> connection module -> rack -> IO channel -> channel bit number, and there is also a function block instance bit number belonging to the controller, which can be hierarchically decomposed according to the controller -> function block library -> function block type -> function block bit number instance.

[0061] The association relationship between the control domain and the operation domain, as shown in Figure 5 As shown, the operation domain can usually monitor one or more control domains, and the monitoring relationship is shown in the figure by the connection relationship. Taking the operation domain 0 as an example, it can be seen that the operation domain 0 monitors the control domain 0 and the control domain 1.

[0062] The connection relationship between the internal hardware structures of the controller includes: the connection relationship between the controller and the connection module, the connection relationship between the connection module and the rack, the connection relationship between the rack and the IO module, and the hardware architecture information of the internal hardware channel bit number of the IO module; the data association relationship between the internal function blocks of the controller includes: function block type, function block bit number instance information, etc.

[0063] Step S2 is performed to organize data based on the configuration data to form corresponding data structures.

[0064] Specifically, the data is organized based on the four association relationships of the configuration data to form four different data structures, and all component association relationships are obtained according to the component address information in each data structure.

[0065] As shown in Figure 2 It can be seen that the host node list in the operation domain is obtained from Figure 3 It can be seen that the controller list in the control domain is obtained from Figure 5 It can be seen that the association relationship between the operation domain and the control domain, so the operation domain is expanded into a host node, and the control domain is expanded into a controller node, and the association relationship between the operation domain and the control domain is expanded, to obtain the monitoring relationship between the host node and the controller, thereby forming the first layer and the second layer of the hardware architecture display data, and Figure 4 The hardware architecture and the function block asset relationship in the controller are displayed, which can be expanded to the third layer to the fifth layer of the graphic data relationship, and the channel bit number and the function block bit number list information are displayed in the last list.

[0066] Step S3 is performed to draw the hardware architecture based on the data structure, and the hardware structure displays the logical relationship between the software and hardware structures contained in the hardware architecture in a hierarchical structure; the controller is expanded according to the hierarchical relationship to expand the connection relationship between the internal hardware structures of the controller and the data association relationship between the internal function blocks of the controller.

[0067] Specifically, the overall hardware architecture association and display structure are obtained based on the component address information in each data structure, and the hardware architecture is drawn according to the obtained overall hardware architecture association and display structure.

[0068] The hierarchical data information of the hardware architecture can be obtained by step S2, and therefore the hardware architecture can be drawn layer by layer, and the features include:

[0069] The display mainly includes a drop-down list, a five-layer graphical structure and a channel list. Specifically, the drop-down list displays a list of all operation domains of the control system. When an operation domain is selected, the first layer node displays all domain server and operation station nodes under the operation domain. The second layer node displays all controller nodes under the control domain monitored by the operation domain. The third layer node displays the connection module nodes belonging to the second layer controller and a fixed function block list, which changes when the selected controller of the second layer changes. The fourth layer node displays the rack node list belonging to the selected connection module node of the third layer, or a function block library list when a function block node is selected. The fifth layer node displays the N-channel IO module node list belonging to the selected rack node, or a function block type list. The last drop-down list displays the N-channel bit number list under the IO module node, or the corresponding function block bit number list.

[0070] There are several response modes: when the operation domain selected by the drop-down list changes, the first layer operation domain domain server node and operation station node list in the graph also changes, and the second layer controller node also changes due to the different control domains monitored by the operation domain; when the controller node selected by the second layer changes, the connection module node of the third layer changes; when the connection module or function block node selected by the third layer changes, the rack list or function block library list of the fourth layer also changes; when the rack node selected by the fourth layer changes, the IO module node of the fifth layer also changes, and the function block type of the fifth layer also changes when the function block library node of the fourth layer changes; when the IO module connection node of the fifth layer is selected or the function block type node changes, the bit number (channel bit number or function block bit number) list at the bottom can also change.

[0071] Specifically, the fifth layer redundant IO component is composed of left and right parts, but in the interactive mode, a component is responded.

[0072] The following three important hardware architecture information can be completely displayed through the displayed hardware structure and the response relationship of the operation:

[0073] The ownership and monitoring relationship between the operation domain and the control domain;

[0074] The internal hardware architecture relationships of the controller include the relationship between the controller and the connection module, the relationship between the connection module and the rack, the relationship between the rack and the IO module, and the hardware architecture of the internal hardware channel bits of the IO module;

[0075] The organization of important control program data such as function blocks within the controller, including information such as function block type and function block tag number instance.

[0076] The beneficial effects of this invention are as follows: First, this method can demonstrate the hierarchical relationships between the operational domain and the control domain, as well as among controllers within the domain; second, this method displays the hierarchical structure within the controller according to the hierarchical relationship, and can expand the hierarchical relationship within the controller according to external operational responses; third, this method combines the logical assets within the controller, such as functional blocks, with the hardware architecture for display, and is not limited to hardware architecture logical relationships. Through this invention, the hardware architecture in the control system can be effectively displayed, effectively demonstrating the hardware structural relationships within the control domain, and also demonstrating the association between the control domain and the operational domain.

[0081] The hardware architecture drawing unit draws the hardware architecture based on the data structure; the hardware architecture displays the connection relationship between the hardware and software structures contained in the hardware architecture in a hierarchical structure; the controller is expanded according to the hierarchical relationship to show the connection relationship between the internal hardware structures of the controller and the data association relationship between the internal functional blocks of the controller.
