McHelperReadRandomAsync 方法 (IReadWriteMc, String) |
随机读取PLC的数据信息,可以跨地址,跨类型组合,但是每个地址只能读取一个word,也就是2个字节的内容。收到结果后,需要自行解析数据
Randomly read PLC data information, which can be combined across addresses and types, but each address can only read one word,
which is the content of 2 bytes. After receiving the results, you need to parse the data yourself

示例
MelsecMcNet melsec_net = new MelsecMcNet( "192.168.0.100", 6000 );
OperateResult<byte[]> read = melsec_net.ReadRandom( new string[] { "D100", "D200", "M32", "W100" } );
if (read.IsSuccess)
{
short d100 = melsec_net.ByteTransform.TransInt16( read.Content, 0 );
short d200 = melsec_net.ByteTransform.TransInt16( read.Content, 2 );
short w100 = melsec_net.ByteTransform.TransInt16( read.Content, 6 );
bool[] array = HslCommunication.BasicFramework.SoftBasic.ByteToBoolArray( melsec_net.ByteTransform.TransByte( read.Content, 4, 2 ) );
bool m32 = array[0];
bool m33 = array[1];
bool m34 = array[2];
bool m35 = array[3];
