ModbusTcpNetReadBoolAsync 方法 (String, UInt16)

批量读取线圈或是离散的数据信息，需要指定地址和长度，具体的结果取决于实现，如果富文本地址不指定，默认使用的功能码是 0x01
To read coils or discrete data in batches, you need to specify the address and length. The specific result depends on the implementation. If the rich text address is not specified, the default function code is 0x01.

public override Task<OperateResult<bool[]>> ReadBoolAsync(
	string address,
	ushort length
)

Public Overrides Function ReadBoolAsync ( 
	address As String,
	length As UShort
) As Task(Of OperateResult(Of Boolean()))

public:
virtual Task<OperateResult<array<bool>^>^>^ ReadBoolAsync(
	String^ address, 
	unsigned short length
) override

abstract ReadBoolAsync : 
        address : string * 
        length : uint16 -> Task<OperateResult<bool[]>> 
override ReadBoolAsync : 
        address : string * 
        length : uint16 -> Task<OperateResult<bool[]>>

参数

address: 类型：SystemString
数据地址，比如 "1234"
length: 类型：SystemUInt16
数据长度

返回值

类型：TaskOperateResultBoolean
带有成功标识的bool[]数组
