A PLC (Programmable Logic Controller) is a digital electronic system used for controlling, executing, and monitoring automated machinery. It is widely applied in various fields such as building equipment control, water treatment, energy, and industrial automation, forming a large market scale. With the development of the “New Four Modernizations” in automotive electronics, the growth rate of the PLC market is expected to accelerate further. According to market intelligence company Mordor Intelligence, the PLC market size is projected to reach $12.8 billion by 2024, with a compound annual growth rate of 4.32%, while the Asia-Pacific region is the largest and fastest-growing application market.
Overview of Jihai APM32F407 PLC Applications
The performance metrics of PLC are primarily evaluated through scan cycle, storage capacity, and functionality, with the scan cycle playing a decisive role. The scan cycle is mainly influenced by the number of I/O input points, the execution of instructions by the main control chip, and computations. In cases of complex functionality, higher frequency requirements are also necessary.
The Jihai APM32F407 microcontroller, based on the Arm®Cortex®-M4F advanced core, has a maximum frequency of 168MHz, and supports both floating-point and signed numerical operations. This helps improve the PLC scan cycle performance, allowing for basic logic controls such as bitwise AND, OR, NOT, and XOR.
