A device may be composed of different items for which different components may be used for the graphical display in the schematic. The components belonging to a device may be distributed over several project pages; in this case we refer to a "distributed display" of the device. All components belonging to the same device receive the same device tag. EPLAN automatically adds a cross-reference to all components with the same device tag.
Preconditions:
- You have opened a project that contains several multi-line schematic pages.
- Under Options > Settings > Projects > "Project name" > Cross-references / contact image > General, you have defined the display settings for cross-references.
- You have placed a function on one of the schematic pages (e.g. a contactor coil).
- You have placed further functions on other schematic pages (e.g. NO contacts).
- All functions have different device tags.
- Select the menu item Project data > Devices > Navigator.
- Select all newly inserted functions in the device navigator.
- Select Popup menu > Properties.
- In the Displayed DT field of the <Function category> tab of the Properties <...> dialog, specify the DT that is to receive all selected functions.
- Click [OK].
Cross-references are now generated and displayed at the affected components in the schematic. The display of the cross-references depends on the display settings.
Create device cross-references between multi-line and single-line representations
Cross-references can also be created between devices in schematic pages having multi-line and single-line representations.
Preconditions:
- You have opened a project.
- You have loaded a multi-line and a single-line symbol library into your project.
- You have created a multi-line schematic page.
- You have created a single-line schematic page.
- Under Options > Settings > Projects > "Project name" > Cross references / contact image > Display, in the Display device cross-references group box, you have specified that cross-references between multi-line and single-line representations are to be displayed, and vice-versa.
- Open the multi-line schematic page and insert a multi-line symbol from the Multi-line symbol library.
- Enter the device tag into the properties dialog and click [OK].
- Open the single-line schematic page and insert an appropriate symbol from the Single-line symbol library.
- Enter the same device tag into the properties dialog and click [OK].
- Open both pages in separate editors to observe the cross-reference display.
Example: On a multi-line schematic page you have inserted a 3-pole switch from a multi-line symbol library and given it the device tag "-Q1" (left side of the illustration). You have also inserted the same symbol (in single-line representation) into a single-line schematic page from a single-line symbol library and given it a device tag of "-Q1" (right side of the illustration). The cross-reference is now generated and displayed with the components on both pages.
The 3-pole switch "Q1" on the multi-line schematic page (left) points to the 3-pole switch "Q1" on the single-line representation (right) and vice-versa.
