## Profile Name Field

Profile name field is used for looking the device profile name in some variable.

An **Identifier** type is a unique ID assigned to a node within the OPC-UA server. It is used to directly reference 
specific nodes without navigating through the namespace hierarchy.

The **Identifier** type in the OPC-UA connector configuration can be used in various forms to uniquely reference nodes 
in the OPC-UA server's address space. Identifiers can be of different types, such as numeric (**`i`**), string (**`s`**), 
byte string (**`b`**), and GUID (**`g`**). Below is an explanation of each identifier type with examples.

- ##### Numeric Identifier (**`i`**)
  A **numeric identifier** uses an integer value to uniquely reference a node in the OPC-UA server.

  ###### Example:
  Gateway expects that the node exist and the value of **ns=2;i=1235** node is “**thermostat**”.

  _Expression:_

  **`Device ${ns=2;i=1235}`**

  In this example, created device on platform will have “**thermostat**” profile name.

- ##### String Identifier (**`s`**)
  A **string identifier** uses a string value to uniquely reference a node in the OPC-UA server.

  ###### Example:
  Gateway expects that the node exist and the value of **ns=3;s=TemperatureSensorType** node is “**thermostat**”.

  _Expression:_

  **`Device ${ns=3;s=TemperatureSensorType}`**

  In this example, created device on platform will have “**thermostat**” profile name.

- ##### Byte String Identifier (**`b`**)
  A **byte string identifier** uses a byte string to uniquely reference a node in the OPC-UA server. This is useful for 
  binary data that can be converted to a byte string.

  ###### Example:
  Gateway expects that the node exist and the value of **ns=4;b=Q2xpZW50RGF0YQ==** node is “**thermostat**”.

  _Expression:_

  **`Device ${ns=4;b=Q2xpZW50RGF0YQ==}`**

  In this example, created device on platform will have “**thermostat**” profile name.

- ##### GUID Identifier (**`g`**)
  A **GUID identifier** uses a globally unique identifier (GUID) to uniquely reference a node in the OPC-UA server.

  ###### Example:
  Gateway expects that the node exist and the value of **ns=1;g=550e8400-e29b-41d4-a716-446655440000** node is 
  “**thermostat**”.

  _Expression:_

  **`Device ${ns=1;g=550e8400-e29b-41d4-a716-446655440000}`**

  In this example, created device on platform will have “**thermostat**” profile name.
