AllenBradleyNetWriteTag 方法

使用指定的类型写入指定的节点数据,类型信息参考API文档,地址支持协议类型代号信息,例如 "type=0xD1;A"
Use the specified type to write the specified node data. For type information, refer to the API documentation. The address supports protocol type code information, such as "type=0xD1;A"

命名空间:  HslCommunication.Profinet.AllenBradley
程序集:  HslCommunication (在 HslCommunication.dll 中) 版本:11.0.5.0 (11.0.5.0)
语法
public virtual OperateResult WriteTag(
	string address,
	ushort typeCode,
	byte[] value,
	int length = 1
)

参数

address
类型:SystemString
节点的名称 -> Name of the node
typeCode
类型:SystemUInt16
类型代码,详细参见AllenBradleyHelper上的常用字段 -> Type code, see the commonly used Fields section on the AllenBradleyHelper in detail
value
类型:SystemByte
实际的数据值 -> The actual data value
length (Optional)
类型:SystemInt32
如果节点是数组,就是数组长度 -> If the node is an array, it is the array length

返回值

类型:OperateResult
是否写入成功 -> Whether to write successfully

实现

IReadWriteCipWriteTag(String, UInt16, Byte, Int32)
备注
关于参数 length 的含义,表示的是地址长度,一般的标量数据都是 1,如果PLC有个标签是 A,数据类型为 byte[10],那我们写入 3 个byte就是 WriteTag( "A[5]", 0xD1, new byte[]{1,2,3}, 3 );
Regarding the meaning of the parameter length, it represents the address length. The general scalar data is 1. If the PLC has a tag of A and the data type is byte[10], then we write 3 bytes as WriteTag( "A[5 ]", 0xD1, new byte[]{1,2,3}, 3 );
