实现
IReadWriteNetReadInt16Async(String)示例
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 );
short d100 = (await melsec_net.ReadInt16Async( "D100" )).Content;
OperateResult<short> R_d100 = await melsec_net.ReadInt16Async( "D100" );
if (R_d100.IsSuccess)
{
short value = R_d100.Content;
}
else
{
}
