Referring to fig. 2, the method for displaying operation logic of a distributed control system provided by the present application is applied to a monitoring device deployed on an electronic device provided by the foregoing embodiment, where the distributed control system includes: the system comprises a controller and monitoring equipment, wherein a display interface is provided on the monitoring equipment.
It should be understood that in other embodiments, the distributed control system operates a logic demonstration method in which the order of some of the steps may be interchanged as desired, or some of the steps may be omitted or deleted. As shown in fig. 2, the method includes:
S201, responding to triggering operation of a user on a target control on a display interface, and acquiring a logic diagram file associated with the target control.
Wherein the logic file comprises: the target logic diagram is used for representing control logic of the operation of the distributed control system and real-time values in the calculation process of the control logic, and the control logic is operated in the controller.
Optionally, the logic diagram is a functional block diagram of all (or part) of each device in the DCS system after being pre-configured, and each element in the logic diagram is a data reference and a functional block in the functional block diagram of all (or part) of each device after being configured. Correspondingly, the identification information among the elements is data reference or attribute information of the functional block, such as the bit number of the functional block and the name of the bit number bound by the data reference; the association information among the elements is the connection relation among all (or part of) functional blocks and between the functional blocks and the data references in the configured functional block diagram. The data reference can bind a position number (namely, field process variables in the DCS system, such as temperature, air pressure and the like), and the connection relation between the functional blocks and the data reference can be connected through an input-output pin connection line.
It should be understood that the connection relationship between the functional blocks and the data references may characterize the transfer relationship between the input and output values of each device in the DCS system.
Alternatively, the attribute information of the target logic diagram may include: the size, name, and coordinate points of the logic diagram, and the like.
For example, the logical graph file may be a pic format file.

As shown with reference to fig. 3, at least one control of open logic diagram 1, open logic diagram 2, etc. is displayed on the presentation interface. The logic diagram 1 is used for representing control logic of the DCS system when the field instrument 1 operates, and the logic diagram 2 is used for representing control logic of the DCS system when the sensor 1 operates.
In the whole operation process of the DCS system, when a user needs to check the control logic of the field instrument 1, the monitoring equipment responds to the triggering operation of the user on opening the logic diagram 1 in the display interface, and obtains a logic diagram file associated with the target control of opening the logic diagram 1.
S202, performing deserialization processing on the logic diagram file to generate a target logic diagram.
Optionally, the data with the specified format in the logic image file may be subjected to deserialization processing, the data with the specified format in the logic image file is converted into structured data, and a target logic image is generated according to the converted structured data. For example, referring to fig. 4, a target logic diagram is generated after reverse serialization.
S203, outputting the target logic diagram to the display interface.
On the basis of the embodiment, the generated target logic diagram can be output to the display interface, so that a site industrial personal can check data reference and function block connection logic in all (or part of) FBD function block diagrams after being pre-configured according to each device in the DCS from the target logic diagram, and can check information such as real-time data reference and real-time values of the function blocks, thereby assisting the site industrial personal to accurately judge the current running state of the DCS, and achieving the effect of improving the running safety of the distributed control system.
For example, with continued reference to FIG. 4, the field operator can view from the logic diagram shown in FIG. 4 that the data reference of the first input pin binding of the ADD function block is AI00020000.PV, e.g., AI00020000.PV, for identifying the values generated when the field instrument 1 is running in the DCS system, i.e., the real-time value when the current field instrument 1 is running is 1.0000.
