Viewing pages
How pages are organized and used day to day — the Pages panel, pinning, tags, trends and documents, fullscreen, and history replay.
Once a page is built, most people view it rather than edit it. View mode is the operator’s screen: live values, working interactions, and a set of side panels — and no editing tools.
Organizing pages
A project can have many pages, arranged into folders to keep them manageable. One page can be set as the project’s default page — the one that opens first when someone enters the project.
The Pages panel
The panel on the left of a page you’re viewing has two parts:
- Pinned — your own shortlist.
- Pages — the project’s full folder tree, to browse or search.
Pinning pages
Hover a page in the tree and pin it. It moves to the top of the panel, and stays there every time you come back.
Pins are yours alone and per project — pinning a page doesn’t change what anyone else sees, and each project has its own list. On a site with two hundred pages, pinning the five you actually work with turns the panel from a filing cabinet into a dashboard. Unpin from either list when it’s no longer one of them.
If you also use the older HMI interface, its favorites and these pins are the same list.
The tags panel
Alongside the page, a panel lists the tags on it with their live values, and lets you change the ones that are writable — so you can read and adjust without hunting through the Tags view. You can manage which tags it shows.
If a value shows Error, hover it: a tooltip names the tag and says whether it couldn’t be found or has a value error.
Trends and documents on a page
A page can carry attached trends and documents, set on the page’s settings. In view mode they appear as quick links in the side panel, so the chart and the manual for a piece of plant are one click from the diagram of it rather than two sections away. A page with nothing attached says so.
Attach the trend an operator would reach for while looking at the page, and the manual they’d need if something on it went wrong.
Creating a trend from a page
You can build a trend out of the tags already on a page, without knowing where they live in the tag tree.
Choose Create trend in the toolbar. The page enters a selection mode:
- The side panel lists every trendable tag on the page. Tick the ones you want, or use Select all.
- The page itself shows markers on the elements those tags belong to, so you can pick straight off the diagram — click the pump you’re interested in rather than finding its tag by name.
- A bar shows how many tags you’ve selected. Confirm it, give the trend a name and an ownership (private or shared), and create it.
Only tags marked as trendable on the page appear. If the panel says there are none, the page’s elements haven’t declared any — that’s set in the editor, not here.
This is much the fastest way to build a comparison chart: open the plant diagram, tick the four temperatures you’re comparing, done.
Presenting
- Preview — view a page the way operators see it while you’re still editing, without leaving the editor. Hold P to peek and release to go back.
- Fullscreen (F) — a clean, chrome-free display, suited to wall boards and control-room panels.
History replay
A page can replay history — instead of only showing live values, it plays back recorded data over a period you choose, animating the page as the building behaved at that time. Use it to review an incident or see how a system ran overnight.
What’s replayed comes from the tags’ history, so a tag with history turned off stays blank during a replay.
A long period at a fine resolution can ask for more data than can be returned at once. If that happens you’re told the range and resolution would return too much data — choose a shorter range, or a coarser grouping, and try again.
Reusing pages
Pages can be exported to a file and imported into another project, so a proven diagram can be reused rather than rebuilt. Elements can also be copied and pasted directly between two pages open in different browser tabs. To label and wire up many tags on a page at once, see Automation rules.
