-> OperateResult<bool[]>
参数
- mc
- 类型:HslCommunication.Profinet.Melsec.HelperIReadWriteMc
[缺少 "M:HslCommunication.Profinet.Melsec.Helper.McHelper.ReadBool(HslCommunication.Profinet.Melsec.Helper.IReadWriteMc,System.String,System.UInt16,System.Boolean)" 的 <param name="mc"/> 文档]
- address
- 类型:SystemString
数据地址 - length
- 类型:SystemUInt16
数据长度 - supportWordAdd (Optional)
- 类型:SystemBoolean
[缺少 "M:HslCommunication.Profinet.Melsec.Helper.McHelper.ReadBool(HslCommunication.Profinet.Melsec.Helper.IReadWriteMc,System.String,System.UInt16,System.Boolean)" 的 <param name="supportWordAdd"/> 文档]
返回值
类型:
OperateResultBoolean带有成功标识的 bool[] 数组
备注
当读取的长度过大时,会自动进行切割,对于二进制格式,切割长度为7168,对于ASCII格式协议来说,切割长度则是3584
对于X,Y类型的地址,有两种表示方式,十六进制和八进制,默认16进制,比如输入 X10 是16进制的,如果想要输入8进制的地址,地址补0操作,例如 X010
