[Abstract]:Based on the idea of object-oriented programming, the sequential control, complex loop control, single loop control and load operation control are developed by using STEP7 CFC modular programming function. General AI and alarm interlocking and other standardized program function blocks. This series of standardized program function blocks are formally programmed, configured and applied in a petrochemical heat medium furnace control system. The relevant program function blocks are further improved and optimized through field testing, debugging and starting up. Finally, the control system achieves the predefined control function and control target, and achieves the expected control precision. The successful application of the standard modular program function block in this project provides a standard modular programming and debugging platform for the heat medium furnace control system, which meets the requirements of engineering, systematization and standardization of the heat medium furnace system.
