以下为三菱的连接对象示例,其他的设备读写情况参照下面的代码:
MelsecMcNet melsec_net = new MelsecMcNet( "192.168.0.100", 6000 );
string d100_value = melsec_net.ReadString( "D100", 5 ).Content;
OperateResult<string> R_d100_value = melsec_net.ReadString( "D100", 5 );
if (R_d100_value.IsSuccess)
{
string value = R_d100_value.Content;
}
else
{
}
