变频器串口通信控制检测的软件编程

对于变频器回送的状态信息则利用Windows的消息处理函数OnComm（）进行处理。在消息处理函数中，将变频器回送的14个状态字一次全部读到所定义的变量参数中，然后程序再从变量参数中分别读取各状态字，在屏幕上显示、判断并报警。-Inverters Detect serial communication control software programming for the inverter loopback status of the information using the Windows message handle function OnComm () for processing. In the message handler will Inverters loopback status of 14 characters all at once read the definition of variable parameters, then process parameters from the variables separately to read the status character on the screen to determine and report to the police.
