MemobusHelperReadAsync 方法 |
批量读取字节数组信息,需要指定地址和长度,返回原始的字节数组
Batch read byte array information, need to specify the address and length, return the original byte array
命名空间:
HslCommunication.Profinet.YASKAWA.Helper
程序集:
HslCommunication (在 HslCommunication.dll 中) 版本:12.1.2.0 (12.1.2.0)
语法 public static Task<OperateResult<byte[]>> ReadAsync(
IMemobus memobus,
string address,
ushort length
)
Public Shared Function ReadAsync (
memobus As IMemobus,
address As String,
length As UShort
) As Task(Of OperateResult(Of Byte()))
public:
static Task<OperateResult<array<unsigned char>^>^>^ ReadAsync(
IMemobus^ memobus,
String^ address,
unsigned short length
)
static member ReadAsync :
memobus : IMemobus *
address : string *
length : uint16 -> Task<OperateResult<byte[]>>
参数
- memobus
- 类型:HslCommunication.Profinet.YASKAWA.HelperIMemobus
[缺少 "M:HslCommunication.Profinet.YASKAWA.Helper.MemobusHelper.ReadAsync(HslCommunication.Profinet.YASKAWA.Helper.IMemobus,System.String,System.UInt16)" 的 <param name="memobus"/> 文档]
- address
- 类型:SystemString
数据地址 - length
- 类型:SystemUInt16
数据长度
返回值
类型:
TaskOperateResultByte带有成功标识的byte[]数组
备注
地址默认使用功能码03,如果需要指定其他的功能码地址,需要手动指定功能码,例如:x=4;100, x=9;100, x=10;100, 当然也可以写成 x=0x0A;100
The address uses function code 03 by default. If you need to specify other function code addresses,
you need to manually specify the function code, for example: x=4;100, x=9;100, x=10;100, of course, it can also be written as x=0x0A; 100
