KUKA KSS01005 Software Option Missing – Causes, Diagnostics & How to Fix

Error Code Overview

• Error Code: KSS01005
• Category: Software Configuration / Licensing / Tech Packages
• Severity: Medium
• System: KRC Controller / WorkVisual / KSS (KUKA System Software)
• Impact: Required software functions are unavailable; related commands may fail or trigger syntax errors

Quick Fix for KUKA KSS01005 Software Option Missing

If KUKA KSS01005 appears, check the following first:

• Verify the required software option is installed
• Check license status in KUKA License Manager
• Confirm the WorkVisual project matches installed tech packages
• Review recent updates, restores, or deployments
• Reinstall missing software packages if needed
• Restart the controller after changes

👉 In most cases, this error is caused by missing tech packages or license issues, not hardware faults.

What KUKA KSS01005 Actually Means

KSS01005 indicates that the controller is trying to use a software option or technology package that is not installed, not activated, or not recognized.

Common KUKA software options include:

• SafeOperation
• ConveyorTech
• ForceTorqueControl
• RSI (Robot Sensor Interface)
• EthernetKRL
• Other motion or process-specific packages

If a program, project, or configuration references one of these—but the controller cannot find it—the error is triggered.

In short:
The robot is calling a feature that does not exist on the controller.

Typical Symptoms on Site

• KRL commands fail to compile
• Programs stop when calling specific functions
• SmartHMI displays “Software option missing”
• Certain menus or features are unavailable

Common Causes of KUKA KSS01005

1. Missing Tech Package Installation

The most common cause is that the required software package was never installed.

• Program uses ConveyorTech but it is not installed
• Project references SafeOperation without installation
• EthernetKRL commands used without the package present

2. License Not Activated or Expired

Some KUKA options require valid licensing.

• Missing license
• Expired license
• Invalid or corrupted license file
• License not properly imported

3. WorkVisual Project Mismatch

A deployed project may reference software modules not installed on the robot.

• Projects copied between robots
• Restored backups from different configurations
• Offline projects deployed without validation

4. KSS Version Incompatibility

After upgrading KSS:

• Older tech packages may become incompatible
• Unsupported versions may fail to load

This can trigger KSS01005 even if the package appears installed.

5. Corrupted Installation or Restore Failure

Improper shutdowns or failed updates may damage:

• Package registration files
• Option configuration files
• Installation directories

How to Troubleshoot KUKA KSS01005

Step 1 – Identify the Missing Option

• Check SmartHMI or log messages
• Identify which function or package triggered the error

Step 2 – Check Installed Tech Packages

• Review installed options in SmartHMI or WorkVisual
• Confirm all required packages are present and active

Step 3 – Verify License Status

• Check KUKA License Manager
• Ensure licenses are valid and correctly installed

Step 4 – Compare WorkVisual Project

• Run Online vs Offline Compare
• Verify project requirements match controller configuration

Step 5 – Reinstall Missing Package

• Install from original media
• Import license if required
• Restart controller

Recommended Tools

👉 Hardware replacement is rarely required unless storage failure causes software corruption.

Pro Diagnostic Tip

Before deploying any project in WorkVisual, always run:

Compare → Online vs Offline

This quickly reveals:

• Missing tech packages
• Unsupported options
• Version mismatches

Most KSS01005 issues are caused by deploying incompatible projects.

How to Fix KUKA KSS01005

• Install the required software package
• Activate or renew the license
• Remove unsupported commands if the option is not required
• Align WorkVisual project with controller configuration
• Reinstall corrupted modules if necessary

How to Prevent KUKA KSS01005

• Maintain backups before updates
• Track installed licenses and package versions
• Verify compatibility before KSS upgrades
• Always compare projects before deployment
• Document software requirements for each robot

Recommended Maintenance Plan

• Before deployment: Run project comparison
• After updates: Verify option availability
• Regularly: Check license validity
