Data flow and software flow of the control system

Data flow direction

The PLC module reads the field data (standard 4-20 mA signal) through the analog input module, and converts it into standard engineering units through program calculation according to the range of the instrument; reads the pulse signal of the flowmeter through the high-speed counting module

The measurement subroutine is called by the main program, and the instantaneous value and cumulative value of the flow are calculated according to the pulse/flow ratio; the calibration of the flowmeter is realized by reading the position switch status of the volumetric tube through the switch input and output module, and controlling the start and stop of the volumetric tube ;

The IPC uses the communication module to read data from the PLC, and records it in the local historical database. The application program reads and displays the field data and the instantaneous and cumulative values ​​of the flow; at the same time, the PLC module also reads the data through the communication module. And execute the operation instruction of IPC;

The PLC transmits the collected and calculated parameters of the inspected flowmeter to the IPC, and the IPC calls the Excel report system for recording. After the calibration is completed, the calibration report and calibration conclusion will be automatically printed out.

Software flow

Software flow in the control system refers to the sequence of operations and processes that are executed by the software to achieve desired results. It involves the flow of instructions, algorithms, and programs that are used to control and regulate the system.

The software flow in the control system starts with the input of data or commands from users or other systems. This data is then processed by the software, which interprets and analyzes the information to determine the appropriate response or action. The software then executes the necessary operations and processes to achieve the desired outcome. This may involve controlling motors, adjusting settings, or communicating with other systems.
