# Addressing Addressing of monitored items is done using the following template: ``` ns=NAMESPACE_INDEX;ADDRESS_TYPE=ADDRESS@DATA_TYPE, where NAMESPACE_INDEX specifies the namespace index, ADDRESS_TYPE specifies the type of address used (number, string, GUID, byte string), ADDRESS specifies the identifier of the item being monitored, and DATA_TYPE specifies the target data type. ``` The following are examples of available addresses: * ns=2;i=15\@FLOAT * ns=2;s=Device1.Group2.Tag3\@INT * g={066779c4-1598-4eb0-b7a8-553798052ea2}@DOUBLE * ns=1;b=SGVsbG8gd29ybGQ=@DOUBLE --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
