SiemensS7NetReadBoolAsync 方法 (String) |
读取指定地址的bool数据,地址格式为I100,M100,Q100,DB20.100
reads bool data for the specified address in the format I100,M100,Q100,DB20.100
命名空间:
HslCommunication.Profinet.Siemens
程序集:
HslCommunication (在 HslCommunication.dll 中) 版本:12.1.2.0 (12.1.2.0)
语法 public override Task<OperateResult<bool>> ReadBoolAsync(
string address
)
Public Overrides Function ReadBoolAsync (
address As String
) As Task(Of OperateResult(Of Boolean))
public:
virtual Task<OperateResult<bool>^>^ ReadBoolAsync(
String^ address
) override
abstract ReadBoolAsync :
address : string -> Task<OperateResult<bool>>
override ReadBoolAsync :
address : string -> Task<OperateResult<bool>>
参数
- address
- 类型:SystemString
起始地址,格式为I100,M100,Q100,DB20.100 ->
Starting address, formatted as I100,M100,Q100,DB20.100
返回值
类型:
TaskOperateResultBoolean是否读取成功的结果对象 -> Whether to read the successful result object

对于200smartPLC的V区,就是DB1.X,例如,V100=DB1.100

示例
假设读取M100.0的位是否通断
SiemensS7Net siemens = new SiemensS7Net( SiemensPLCS.S1200, " 192.168.1.110" );
bool X1 = siemens.ReadBool( "M100.0" ).Content;
OperateResult<bool> R_X1 = siemens.ReadBool( "M100.0" );
if (R_X1.IsSuccess)
{
bool value = R_X1.Content;
}
else
{
}
