# LGF_TaddrToString (FC / 3.0.1)

Overview

Author: Siemens Digital Industry

## Short description

The system data type `TADDR_Param` contains address information consisting of an IPV4 address and the port number.

The `LGF_TaddrToString` function converts a `TADDR_Param` system data type variable to a `String` data type variable.

### Block Interface

| LGF_TaddrToString (FC) |
--- | --- | ---
TADDR_Param |  |  | ipAdressTaddr |  | Ret_Val |  |  | String

### Input parameter

Identifier | Data type | Description
--- | --- | ---
ipAdressTaddr | TADDR_Param | IP-Address and Port number to convert into string

### Output parameter

Identifier | Data type | Description
--- | --- | ---
Ret_Val | String | IP-Address and Port number as string

## Functional description

The function converts the IPV4 address with or without port number. The system data type `TADDR_Param` is a structured data type. This structure contains the variable `REM_PORT_NR`. If this variable is 0, no port is written to the parameter `Ret_Val`.

### Example Result at `Ret_Val`:

- The standard string format for an IPV4 address without port number:
  `192.168.11.11`
- The standard string format for an IPV4 address with port number:
  `192.168.11.11:3294`
