# Fronius TPS/i

This page describes how to integrate and set up communication between Fronius TPS/i series power sources and SmoothTool X.

## Hardware Configuration

SmoothTool X is compatible with Fronius TPS/i series power sources. To set up communication between the software and a power source, the following items are required:

- **Fronius products** (contact your local Fronius dealer for more information):
  - The **RI FB Inside/i** interface, configured for the **Ethernet/IP** protocol.
  - One of the following Ethernet/IP modules:
    - *RI MOD/i CC-M40 Ethernet/IP-2P*
    - *RI MOD/i CC Ethernet/IP-2P*
- Ethernet RJ45 cable from the power source to the robot.

Note

SmoothTool X communicates with the Fronius TPS/i over the standard **Ethernet/IP** protocol. Set this protocol on the Fronius interface itself, following the interface's instruction manual — it is not configured in SmoothTool X.

### RI FB Inside/i Interface — IP Address

Before installing the RI FB Inside/i interface, select a valid IP address for the interface. The IP address must be on the same subnet as the robot.

- If the selected IP address falls under **192.168.0.X**, specify the last octet using the 8 physical dip-switches on the interface. Each dip-switch represents one bit of the missing byte.
- If the selected IP address does not fall under 192.168.0.X, set all dip-switches to 0 and configure the IP address via the web interface of the power source.

More information about setting the IP address can be found in the interface instruction manual. Visit the [Fronius download page](https://www.fronius.com/en/download-center) to acquire it.

### Installing the Interface and Module

After setting the physical dip-switches, install the RI FB Inside/i interface by following its instruction manual. Then insert the Ethernet/IP module into the suitable slot, fasten it with two screws, and connect the module to the robot using the Ethernet cable.

## Software Configuration

Once the hardware is configured, add and connect the Fronius TPS/i in SmoothTool X.

### Add the Fronius TPS/i

Tap **SmoothTool X Settings** from the Application view. In the sidebar, under **Components**, tap **Power Sources**, then tap **Add new power source**.

 ![Power Sources page with the Add new power source button](https://hub.smooth-robotics.com/wp-content/uploads/2026/09/manual-power-sources-fronius-power-sources-tab.webp)

In the **Add power source** dialog, select the **Fronius** tile and choose the **Fronius TPS/i** model, then tap **Add power source**.

### Configure the Fronius TPS/i

Fill in the configuration fields:

| Field | Description |
| --- | --- |
| Custom name | A name to identify this power source. |
| Power source IP address | The IP address you set for the interface. The robot uses this address to communicate with the power source. Ensure it is set correctly; otherwise the robot cannot connect. |
| Configure parameters in the software | Controls whether program nodes override the power source parameters at runtime — see [Configure parameters in the software](#configure-parameters-in-the-software) below. |

When done, tap **Done** to save the power source.

#### Configure parameters in the software

The **Configure parameters in the software** toggle controls how welding parameters are applied:

- **Disabled** (default) — the power source keeps the parameters set on the machine; program nodes do not override them.
- **Enabled** — program nodes override the power source parameters at runtime, letting you set welding parameters per node from the weld node's Power source tab.

### Connect to the Fronius TPS/i

Back on the **Power Sources** page, expand the new entry, tap **Selected** to make it the active power source, then tap **Connect**. When the connection is established, a connection status tag is shown on the entry.

## Programming with SmoothTool X and Fronius TPS/i

When **Configure parameters in the software** is enabled, you can adjust the welding parameters per node from the program tree.

Select a weld node (e.g. Weld Seam) in the program tree and open its **Power source** tab. The parameters apply when the program reaches that node.

The power source offers two methods for setting the weld parameters: **Job number mode** and **Synergic mode**.

### Job number mode

Select **Job number mode** to run a predefined weld data number stored on the power source.

| Identifier | Description |
| --- | --- |
| Job number | The job containing predefined parameters stored on the Fronius power source. |
| Transfer parameters | Sends the current parameters to the power source. Available once connected. |

Note

In Job number mode the power source uses the parameters stored under the selected job; wire feed speed, arc length, dynamic, and synchro pulse cannot be overridden. Use **Synergic mode** if you need to override those.

### Synergic mode

Select **Synergic mode** to find the right synergic line through a guided wizard. Tap **Guided setup** and follow the steps to select the **Material**, **Wire diameter**, **Gas**, **Process**, and **Property**. You can also enter a known **Synergic line number** directly. Once a line is selected, the button collapses to an edit icon you can tap to change the selection.

Once a synergic line is selected, the parameters below become available:

| Identifier | Description |
| --- | --- |
| Arc length correction | Desired arc length correction. |
| Dynamic correction | Desired dynamic correction. |
| Wire feed speed | Desired wire feed speed. |
| Synchro pulse | Enable or disable synchro pulse. |
| Transfer parameters | Sends the current parameters to the power source. Available once connected. |

### Manual power source controls

The manual controls live in the **Power source** popover, opened from the button in the operator screen toolbar.

 ![Power source popover showing the manual wire-control and test functions](https://hub.smooth-robotics.com/wp-content/uploads/2026/09/manual-power-sources-fronius-manual-controls.webp)

When connected to the Fronius TPS/i, the following manual controls are available:

| Control | Description |
| --- | --- |
| Forward | Feeds the welding wire forward. |
| Backward | Retracts the welding wire. |
| Error reset | Sends a reset-error signal to the power source. |
| Gas | Opens the gas valve for the duration of the press. |

Warning

Connected to a power source that provides the option to control the wire. Do not use these functions without ensuring no harm can come to people or material. Make sure the area around the welding torch is clear before use.

#### Simulation

The **Simulation** toggle at the top of the popover runs the program as a dry run: the robot executes the full program and motion path, but the power source does not weld (no arc, wire feed, or gas). Use it to test a program safely, then turn it off to weld for real.
