PLC返回数据 E5 后,确认读取命令,发送以下数据:
10 2 0 5C 5E 16
然后上位机VB程序接受到以下数据:
68 16 16 68 0 2 8 32 3 0 0 0 0 0 2 0 5 0 0 4 1 FF 4 0 8 22 78 16
首先识别目标地址和源地址,确认是这次申请的返回数据,然后经过校验检查,正确后解析出第26号数据(&H22)即为VB100字节的数据。
3、串口写入数据程序,以写VB100数据单元为例:
Dim Str_Write(0 To 37) ‘定义发送的数据为字节为元素的数组。
Str_Write (37) = &H16 ‘相应的数组元素赋值,按照以下格式
Str_Write (35) = &H10 ‘要写入的数据值
