Serial Communication Program Implementation

In this article, we implement serial communication control using LabVIEW program code. LabVIEW provides a powerful graphical programming environment that enables developers to easily create and configure code for serial communication control. By utilizing LabVIEW's built-in serial communication functions - such as VISA Configure Serial Port, VISA Write, and VISA Read - we can establish robust data exchange with external devices. The implementation typically involves configuring communication parameters (baud rate, data bits, parity, stop bits), managing device control commands, and handling real-time data monitoring through while loop structures with error handling mechanisms. This approach allows for effective device state and parameter control, while supporting real-time monitoring and data logging functionalities through file I/O operations and waveform chart displays. Consequently, we can achieve better management of serial communication control systems, enhancing both system stability and operational efficiency through proper buffer management and timeout configuration.
