How to Use Boolean Expressions for E3.series Searches

Written by Arthur Hoerlle | Dec 02, 2021

In this article, you can check how to use Boolean expressions to search the different tables that E3.series provides for managing your project. Expressions serve to facilitate and speed up the search for certain terms and conditions. See the full video article and optimize your processes!

Insertion of Connectors and E3.formboard Features

The project starts with the insertion of 4 connectors to a formboard sheet. The chosen connectors are "DT04-3P" and "DT04-2P".

DT04-3P Type Connector Example

When inserting database components, E3.formboard automatically provides a list of available views for each connector and table insertion is automatic.

Rename Available Devices and Settings

After adding the connectors, two of them are renamed to further optimize the search example with the logical expressions. The connectors "-X3" and "-X4" are renamed respectively as "-A3" and "-B4".

Device Properties window

For this, the "Device Properties" window is accessed by clicking the right mouse button on the devices in the sheet. Then the "Device Designation" field in the "Device" window is used for name change. Some configuration options in this window are:

  • Device Designation
  • Higher Level Assignment
  • Location

Search with Boolean Expressions

Boolean expression search works on pin tables, device tables, spreadsheet tables, translation tables, and connection tables.

How to Search Using Boolean Expressions in E3.series

This functionality can be used to search multiple terms within a table, which are connected with Boolean expressions, and the following Boolean operations are available:

  • logical AND (&);
  • logical OR (|);
  • denial (!);
  • combination of terms in parentheses.

To search a table using Boolean expressions, first open any table. To do this, select the command "View" or "Format" - "Translation Table" in the Main Menu and then a table.

Press the "F7" key or right-click on the gear symbol and select "Search".
