使用VB编写的与OMRON PLC 通过HOSTLINK 协议通讯的源码。(Written using VB and OMRON PLC through the HOSTLINK protocol communication source code.)

这是VB和欧姆龙通讯源码经典的例子, Lettura_Dm = False ricez_ok = -1: timeout = False trasm = "@00RD" trasm = trasm + Right$(Str$(10000 + dm!), 4) trasm = trasm + "0001" trasm = trasm + bcc(trasm) + Chr$(42) + Chr$(13) Omron!Comm1.Output

基于微软vb6下平台与下位机，欧姆龙plc通讯源码。(Based on Microsoft VB6 platform and lower computer, Omron PLC communication source code.)
