# 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:

* &#x20;ns=2;i=15\@FLOAT
* &#x20;ns=2;s=Device1.Group2.Tag3\@INT
* &#x20;g={066779c4-1598-4eb0-b7a8-553798052ea2}@DOUBLE
* &#x20;ns=1;b=SGVsbG8gd29ybGQ=@DOUBLE
