Issue
If a variable tag is linked with two trend tags, only one available for trending in WebHMI.
Environment
Power SCADA Operation (PSO) 2020
EcoStruxure Power Operation (EPO) 2021 / 2022
Cause
In WebHMI trend when trying to add a data series, the product is currently designed to get the Measurement (tag) details from the variable tag DB defined against the selected equipment rather than the trend tag DB.
Resolution
If it is required to plot two different sampling interval trends for the same variable tag, it is necessary to create a duplicate of the existing variable tag and make sure
> Tag Name, Item Name and Comment are unique and mandatory to input variable.
> Trend tag name should be same as variable tag name.
Compile and run the project. Now you can add both these variable tags to monitor trend graph in WebHMI.
