LSCpuRead 方法 (String, UInt16) |
从PLC的指定地址读取原始的字节数据信息,地址示例:MB100, MW100, MD100, 如果输入了M100等同于MB100
Read the original byte data information from the designated address of the PLC.
Examples of addresses: MB100, MW100, MD100, if the input M100 is equivalent to MB100
命名空间:

HslCommunication (在 HslCommunication.dll 中) 版本:12.1.2.0 (12.1.2.0)
语法 public override OperateResult<byte[]> Read(
string address,
ushort length
)
Public Overrides Function Read (
address As String,
length As UShort
) As OperateResult(Of Byte())
public:
virtual OperateResult<array<unsigned char>^>^ Read(
String^ address,
unsigned short length
) override
abstract Read :
address : string *
length : uint16 -> OperateResult<byte[]>
override Read :
address : string *
length : uint16 -> OperateResult<byte[]>
