Functional Characteristics Analysis of BCU-02 3AUA0000110429 Multi functional Industrial Control Module

As an industrial control module, BCU-02 3AUA0000110429's core functions revolve around modular design

Inclusion time

The inclusion time refers to the time when functional modules are merged into the software source language description, and there are differences in the inclusion methods for different types of modules. For example, macro function modules are directly inserted into reference positions by compilers, while regular subroutines are incorporated into software by generating object code and connection code.

Activation mechanism

The module supports two activation methods:

Reference call: Trigger module execution through explicit calls in the program;

Interrupt call: In real-time systems, interrupts are often triggered by external events (such as timers, sensor signals) to redirect control to the target module.

Control method

Basic control: Most modules use a single inlet and outlet, executed in sequence;

Advanced Control: Supports reentrant functional modules that do not modify their own or accessed local addresses, can be called by multiple tasks simultaneously, and is suitable for multi-threaded parallel scenarios.

structural classification

According to the execution method, modules can be divided into:

Sequential function module: When there is no obvious interruption, it is called by the application software and executed continuously;

Incremental function module: can be interrupted during the calling process, and can resume execution from the breakpoint after interruption;

Parallel functional module: runs simultaneously with other modules in a multiprocessor environment.
