Installation and Configuration with OGS

OGS Project Configuration

OGS has an interface to add additional tool drivers by adding Windows-DLLs to the [TOOL_DLL] section in station.ini. To simplify the creation of custom tool drivers, OGS offers the heLuaTool.dll, which enables the development of tool drivers using pure LUA. With this functionality, the Stahlwille WiFi torque wrench is seamlessly integrated into OGS. See Lua custom tools for more info.

Tool Registration and Configuration

According to the instructions provided in the Lua custom tools, a standard configuration for the [LuaTool_Stahlwille_WiFi] section in station.ini is as follows:

[TOOL_DLL]
heLuaTool.dll=1 

[CHANNELS]
20=LuaTool_Stahlwille_WiFi 

[LuaTool_Stahlwille_WiFi]
DRIVER=heLuaTool
Type=stahlwille_wifi
; TCP/IP connection parameters (direct WiFi connection)
IPADDR=10.10.2.166
IPPORT=4002

Configuration Parameters

Tool Parameters

  • DRIVER: The name of the Windows DLL that implements tool drivers (heLuaTool).
  • Type: The name of the tool driver specified in your custom LUA tool driver (stahlwille_wifi).
  • IPADDR: IP address for WiFi communication with the tool (e.g., 10.10.2.166).
  • IPPORT: Port number for communication (default: 4002).
  • BUTTON_PRG: Program number used for button confirmation operations (e.g., 98).
  • Debug: Enable debug logging (1 = on, 0 = off).

Tightening Programs

The tool supports multiple tightening strategies with configurable parameters:

Program Format: 

PRG_XX={ "name":"Name", "type":"TYPE", "mode":"clic", "unit":"Nm", "elen":100.0, ... }

Common Parameters:

  • name: Program name (displayed to operator)
  • type: Tightening strategy type (see below)
  • mode: Feedback mode ("clic" for audible click)
  • unit: Torque unit ("Nm" for Newton-meters)
  • elen: Electronic angle measurement length (degrees)

Tightening Strategy Types:

1. JNT (Joint Torque)

Pure torque-based tightening with min/target/max limits.

PRG_01={ "name":"WiFi-JNT", "type":"JNT", "mode":"clic", "unit":"Nm", "elen":100.0, "t_min":6.1, "t_tgt":6.5, "t_max":7.5 }

Parameters: - t_min: Minimum acceptable torque (Nm) - t_tgt: Target torque (Nm) - t_max: Maximum acceptable torque (Nm)

2. JNA (Joint Angle)

Torque threshold with angle monitoring.

PRG_02={ "name":"WiFi-JNA", "type":"JNA", "mode":"clic", "unit":"Nm", "elen":100.0, "t_thr":6.0, "a_min":5, "a_tgt":15, "a_max":25 }

Parameters: - t_thr: Torque threshold to start angle measurement (Nm) - a_min: Minimum acceptable angle (degrees) - a_tgt: Target angle (degrees) - a_max: Maximum acceptable angle (degrees)

3. JTA (Joint Torque + Angle)

Combined torque and angle strategy for critical joints.

PRG_03={ "name":"WiFi-JTA", "type":"JTA", "mode":"clic", "unit":"Nm", "elen":100.0, "t_min":6.1, "t_tgt":6.5, "t_max":7.5, "t_thr":5.0, "a_min":5, "a_tgt":15, "a_max":25 }

Parameters: - Combines all parameters from JNT and JNA strategies - First evaluates torque limits, then angle limits

4. JAT (Joint Angle + Torque)

Torque and angle evaluation where the tool first checks the programmed angle window and then verifies that the final torque remains inside the acceptable range. Use this strategy when the application is primarily angle-driven but still requires torque verification as a safety net.

PRG_04={ "name":"WiFi-JAT", "type":"JAT", "mode":"clic", "unit":"Nm", "elen":100.0, "t_min":6.1, "t_tgt":6.5, "t_max":7.5, "t_thr":5.0, "a_min":5, "a_tgt":15, "a_max":25 }

Parameters: - Angle (a_min, a_tgt, a_max) is validated first once t_thr is reached. - Final torque window (t_min, t_tgt, t_max) is checked after the angle requirement succeeds.

Display Message Configuration

The tool's color display supports 5 lines of text with customizable colors. Messages are configured using JSON format.

Button Confirmation Message:

For operations requiring operator confirmation (using BUTTON_PRG), you can configure a custom message:

BUTTON_MSG={ "text":[ "Please press OK", "", "TO Confirm", "", "" ], "color":[ 6, 7, 1, 7, 7 ] }

Text message displayed on tool

Color Codes:

Code Color
0 Red/Black
1 Green/Black
2 Cyan/Black
3 Yellow/Black
4 Red/Grey
5 Green/Grey
6 Light Blue/Black
7 Grey/Black
8 Cyan/Grey
9 Dark Blue/Black

Note: Line 3 uses a larger font, so keep text short for optimal display.

Program States

During operation, the tool reports the following program states:

State Description
0 No joint in memory
1 Joint active (tightening in progress)
2 Joint inactive
3 Joint passed (successful tightening)
4 Joint failed (tightening outside limits)
5 Fixing detection

Editor Configuration

Configuring the Tool

In the Tools section of the Editor, create a new tool with a name of your choice (e.g., "Stahlwille WiFi") and assign it to the appropriate channel (ensure the channel number matches the one specified in the station.ini file).

Add new tool

Creating a Job

To set up a job and task with the appropriate operations:

  1. In the Jobs catalog of the Editor, create a new job and add a new task.
  2. Add an operation and assign the Stahlwille WiFi tool to it.
  3. Set the Program (Prg) value to match the program number defined in station.ini (e.g., 1 for PRG_01, 2 for PRG_02, etc.).
  4. For button confirmation operations, use the BUTTON_PRG value (e.g., 98).

Job editing

Family Configuration

In the Family tab of the Editor, create a new family. Configure the Model and Barcode mask, then link the newly created job to the family.

Family configuration

Operation

When a job is active, OGS will:

  1. Load the configured tightening program to the tool
  2. Display instructions on the tool's screen
  3. Wait for the operator to perform the tightening
  4. Validate the results against the configured limits
  5. Display success or failure feedback

Tool working in OGS

Job completed

The tool provides immediate visual and audible feedback during tightening, guiding the operator to achieve the target torque and angle values.
