5.3 Plant web page features
A plant web page has an expandable area that can be used to place web page
elements. The display area has a minimum size of 800px (width) and 580px
(height).
The minimum display area is filled with a transparent background image if no
background image is explicitly selected.
• The display area can be expanded to any size by adding a larger
background image.
• The following types are accepted: png, jpg, gif and bmp; we do not
recommend using bmp due to the file size.
Multiple plant web pages are listed from top to bottom in the secondary navigation
per their "Position". The plant web page is built and displayed at "Position"=1 when
going to a home or device node. Use "Position > New > Properties" to set the
"Position" in the secondary navigation or "Properties > Position" for existing plant
web pages.
The following applies to levels within a plant web page:
• The background picture is located in the background.
• The group of partial pictures are in front.
• The group with all remaining elements are in front.
• More recently added elements are on top of previously added elements
within the group of partial pictures and remaining elements.
Please note the following for the last statement:
• If an element is deleted as part of editing and another element added, the
new element jumps to the level of the deleted one. This level is not always
the top level.
• You must add a new element as part of new editing to ensure that the new
elements are placed at the top (finish with OK and re-click edit).
Plant web pages are hidden for a hidden device with appended plant web pages.
The associated plant web pages are displayed again if the device is re-generated
and displayed (Important note in Section 2.8).
Appended plant web pages are irretrievably deleted once a device is deleted.
The same is true when you reset the web server.
Any change to the controller configuration creates differences between the
controller and the mapping on the web server. This impacts plant web pages as
well where data point elements access the controller via the web server map.
You must run "Generate" each time you change the controller configuration
(see Section 2.4 for workflow).
Any number of plant web pages per web server are possible.
• The web server has 180 MB in memory.
• You should pay special attention to image file size to save memory;
(current available memory is available at "File transfer > Documents").
• A maximum of 100 elements may be added on a plant web page from
one web page element type (e.g. a maximum of 100 data point elements).
