## Root Cause and Potential Impact
Based on the information retrieved from the knowledge base, the root cause of the "Welding_Robot_Joint_2_High_Temp" alarm could be:
- The joint temperature has exceeded the high temperature threshold of 80°C, which can indicate a thermal issue with the joint.
- Potential causes include hindered free movement of the joints, incorrect TCP configuration, high payload, or mounting issues.

The potential impact of this alarm is that the welding robot may need to be shut down to prevent further damage to the joint, which could disrupt the production process.

## Mitigation
To mitigate the issue, the following steps can be taken:
- Check that nothing is hindering the free movement of the joints.
- Verify the TCP configuration, payload, and mounting settings are correct.
- If the issue persists, contact the local Universal Robots service provider for further assistance.

Based on the information retrieved from the knowledge base, the following error codes are related to the "Welding_Robot_Joint_2_High_Temp" alarm:

- **C62A1 - Joint temperature: High (80 C)**: This error code indicates that the joint temperature has exceeded the high temperature threshold of 80°C.
- **C62A11 - Joint temperature: Shut down (85 C)**: This error code indicates that the joint temperature has exceeded the shut down threshold of 85°C, and the robot may need to be shut down to prevent further damage.
- **C62A13 - Shutdown: Static load too high**: This error code indicates that the static load on the joint is too high, which can contribute to the high temperature issue.
- **C70A - Close to gearbox shear limit**: This error code indicates that the acceleration or deceleration of the joint is too high, which can also lead to high temperatures and potential mechanical issues with the gearbox.

The knowledge base also provides some recommended mitigation steps, such as:
- Checking that nothing is hindering the free movement of the joints
- Verifying the TCP configuration, payload, and mounting settings
- Reducing the acceleration in the user program
- Performing a complete rebooting sequence
- Replacing the joint if the issue persists

So in summary, the key error codes related to this "Welding_Robot_Joint_2_High_Temp" alarm are C62A1, C62A11, C62A13, and C70A.

# Property Summary

## Frames_Produced_5m at the Welding Station

**Asset Name:** Welding Station
**Property Name:** Frames_Produced_5m
**External ID:** Welding_Station_Frames_Produced_5m

### Property Details and Insights
The historical data for the "Frames_Produced_5m" property at the Welding Station shows a single data point, with a value of 3.0 frames produced, recorded on 2024-12-02T23:45:00Z. As this is the only data point available, it is not possible to analyze any trends or historical patterns. However, the current value of 3.0 frames produced is consistent with the single historical data point, indicating that the production rate has remained stable in the latest resolution window.

### Comparison of Current and Historical Values
The current value of 3.0 frames produced is consistent with the single historical data point available, suggesting that the production rate has remained stable in the latest resolution window.

Since there is only one property present in the provided data, it is not possible to evaluate the values across multiple properties to generate additional insights.

### Overall Summary
Overall, the limited data available for the "Frames_Produced_5m" property at the Welding Station indicates a stable production rate of 3.0 frames produced, based on the single historical data point and the current value. However, more data would be required to analyze any trends or patterns over a longer time period.

**Property Name:** Joint 4 Temperature
**Property Alias:** /Tag Providers/default/UR/Joint_4_Temp
**External ID:** Robot_Joint_4_Temperature
**Unit:** °C

### Property Details and Insights
The analysis of the historical values for the "Joint 4 Temperature" property shows a relatively stable trend over the past 5 minutes, with the temperature ranging from 35.36°C to 35.94°C. The latest value of 35.94°C recorded at 2024-12-02T23:49:23Z is slightly higher than the historical average, but still within the observed range.

## Joint 5 Temperature

**Asset Name:** Welding Robot
**Property Name:** Joint 5 Temperature
**Property Alias:** /Tag Providers/default/UR/Joint_5_Temp
**External ID:** Robot_Joint_5_Temperature
**Unit:** °C

### Property Details and Insights
Comparing the latest value of the "Joint 5 Temperature" property to the historical trend, the current temperature of 37.06°C is slightly elevated compared to the previous 5 minutes, which ranged from 36.59°C to 37.11°C. This suggests a potential increase in temperature for this particular joint.

### Comparison of Properties
Evaluating the values across the two properties, the "Joint 5 Temperature" has consistently been higher than the "Joint 4 Temperature" over the past 5 minutes.

## Joint 4 Temperature

**Asset Name:** Welding Robot
**Property Name:** Joint 4 Temperature
**Property Alias:** /Tag Providers/default/UR/Joint_4_Temp
**External ID:** Robot_Joint_4_Temperature
**Unit:** °C

### Property Details and Insights

The temperature shows a repeating pattern, with peaks and troughs occurring approximately every 4 hours. This suggests that the welding robot's joint 4 temperature follows a diurnal (daily) cycle, likely due to the robot's usage patterns and the surrounding environmental conditions.

The current value of 35.9375°C is within the range of temperatures observed over the past 24 hours. The current value is slightly higher than the average of the last few 15-minute intervals, but it is not significantly different from the typical values seen throughout the day.

## Joint 5 Temperature

**Asset Name:** Welding Robot
**Property Name:** Joint 5 Temperature
**Property Alias:** /Tag Providers/default/UR/Joint_5_Temp
**External ID:** Robot_Joint_5_Temperature
**Unit:** °C

### Property Details and Insights
For the "Joint 5 Temperature" property, the historical values show a more dynamic pattern, with the temperature ranging from around 32.60°C to 37.06°C over the past 24 hours. The temperature appears to follow a similar cyclical pattern to the Joint 4 Temperature, but with more pronounced peaks and troughs. The current value of 37.0625°C is at the higher end of the observed range, indicating that the joint 5 temperature may be slightly elevated compared to the typical values seen throughout the day.

### Comparison of Properties
Overall, the analysis of the historical values for both properties suggests that the welding robot's joint temperatures are generally within expected ranges, with some minor fluctuations over the course of the day.
