@Admin: Please find my answers below:
1. Our Chemicals users would like to have the ability to create one Control Valve view with all five trends scaled for each controller (as mentioned in idea description). Then they would build out a system page of all the controllers in that system for monitoring purposes. A broad system view of all the system controllers is very important for the I&C engineer performing their daily Proactive Technical Monitoring (PTM). Having the option to group scale as described would help them acheive this.
2. It would be good to have this feature as additional option in the existing Trend symbol.
3. Our operators and engineers at the Chemicals and Downstream sites.
More advanced functionality can include a dual axis on the trends with the ability to scale both of them differently.
This is a basic function in Excel and I'm not sure why it isn't included in PI Vision
I want to point out that a request from Shell is that one lower range could be fixed while the multiple 'scale-with' ranges are applied. For example, the lower range set to 0 while other groups are scaled-with each other and the higher range is automatically adjusted based on the output value.
I'll also ask others to share more details of the specific requirements.
