I would like to ask how to add new variables to the historical alarm window in KingView

KingView is an industrial monitoring software (SCADA system) based on the Windows platform, primarily used for data acquisition and process control. Alarm management is an important component of this system, used to monitor and record abnormalities during the manufacturing process. To add new variables to the historical alarm window in KingView, for example to generate alarms based on logic in the PLC (Temperature 1 > Alarm Value 1), you need to follow these steps: 1. **Define the alarm variables**: - In KingView, open the corresponding project. - Go to the variable definition section and create two new variables corresponding to “Temperature 1” and “Alarm Value 1” in the PLC, respectively. - Configure the variables to ensure they can correctly read data from the PLC. 2. **Create alarm conditions**: - In KingView, locate the subsystem related to alarm configuration or alarm management. - Create a new alarm condition to compare “Temperature 1” with “Alarm Value 1”. - Set the alarm condition expression, for example `IF Temperature1 > AlarmValue1 THEN ...`. - Configure other attributes of the alarm, such as alarm severity, messages, and confirmation methods. 3. **Configure historical alarm records**: - Ensure that the aforementioned alarm conditions can be written to the historical alarm records when triggered. - In the historical alarm configuration, it may be necessary to add or ensure that records triggering the alarm condition are collected and stored. 4. **Design and configure the historical alarm window**: - Open or create a historical alarm display window in KingView. - Configure the window to display historical alarm records, including those related to the newly added alarm conditions. 5. **Testing and Debugging**: - Test your alarm logic to ensure that an alarm is properly triggered and recorded when “Temperature 1” in the PLC exceeds “Alarm Value 1”. - Check whether the historical alarm window can display the alarm records correctly. 6. **Save and Run**: - Save your configuration and run the monitoring project in a real environment. - Conduct on-site tests to ensure that all alarm functions are working properly and that historical records are displayed correctly. The exact steps for using KingView may vary slightly depending on the version, so it is best to refer to the user manual or help documents for your specific version when carrying out the configuration. If you encounter specific operational issues, you can also seek help from the software’s technical support. .
