Search options (Page 4 of 6)

Hi, version 0.7.5 is launched. 
The terminal block element can have up to 2 texts. Now the plugin searches in all texts any text with the correct format, i.e "X1:2".

Hi, a new version 0.7.2 is deployed. Now for TB created with no searching implicit connections, the xref for the terminal is showed. A comment in the checkbox remembers the behavior.

Fixed also the bug  [font=Verdana, Helvetica, Arial, sans-serif]when user clicks on button to change "QET user collection path" in config tab.[/font]

To update:

>> Update on Linux
sudo pip3 install --upgrade qet_tb_generator

>> Update on Windows
python -m pip install --upgrade qet_tb_generator

The picture shows the differences between the TB:

Hi, I'm using different software watching the best way to implement a solution in QET.
Galexis, why do you need the previous version? The last version includes old version with some fixes. If you need something different, say me and I could implement a checkbox in the config tab in order to have a different behavior.

Hi Aleksandr, I edited your diagram and I post a sample result.

Any element of type "terminal" will be considered to make the terminal strip.

In the above example, the conductor 313 is connected (in any page) to a terminal. In our case the terminal XA:4. So all the cables with the same potencial are considered connected to this terminal. But the are one exception: if the conductor goes from a PREVIOUS FOLIO to a NEXT FOLIO is not considered a connection (it's only a bridge)

Maybe the problem is that a TERMINAL element keep conductor numbers on it connections, and the script considers that all conductors with same number are interconnected.

I created a new version (0.7.1) and you can disable searching for implicits connections. Check the terminal strip created with the option "Search for implicits connections" unchecked.

I made several tests and I did the algorithm to solve most of the problems, but I'm sure it's not perfect. We need to check and find errors. When will work "perfect", I'll try to implement in QET. But for tests I spend less time modifying the script to find the best way to solve the problem. Later, to put inside QET will be a coding problem, not a programming problem.

I'm finding another software to draw electrical diagrams and check how it solves.

(My english is not good. I'm spanish)

Hi Galexys, the Xref ending by a point are found as implicits connections. Later I'll test your QET file and check why.

In previous versions, the xref refers to the terminal, and now refers to the connected element. The up and down connections depens of the orientation of the terminal in the diagram. If rotates, will change on the terminal strip.

I 've implement a "Connectors" option. In the picture, shows that drawing the red part, we obtain the connector on the green part.

Could someone recommend me a diagram software that I can check to see how it implements  "Block terminals" and "Connectors"?. I need to see some ideas to implement the algorithm yet implemented in QET.

GUIDE TO INSTALL / UPDATE
Requires python 3.5 or above.

>> First install on Linux (tested on xubuntu 16.06)
1. Check python version: python3 --version
   To intall python 3.5:
        sudo add-apt-repository ppa:fkrull/deadsnakes
        sudo apt-get update
        sudo apt-get install python3.5
        sudo rm /usr/bin/python3
        sudo ln -s /usr/bin/python3.5 /usr/bin/python3
2. check you have pip3 installed: pip3 --version.
   If not install with: sudo apt-get install python3-pip
3. Install the program: sudo pip3 install qet_tb_generator
4. Run the program: qet_tb_generator

>> Update on Linux
sudo pip3 install --upgrade qet_tb_generator

>> First install on Windows
1. Install, if required, python 3.5 or above
2. pip install qet_generator

>> Update on Windows
python -m pip install --upgrade qet_tb_generator

I don't understand. In other software, how do you say at what terminal strip belongs every terminal?

With the actual script, specify in the "designation" field where is connected is optional. If you don't put it will use a blank space or create a new one, but if you specificy 1 or 2 it forces North or South.

If we consider that it will be only a one terminal strip, I could search for all terminals, auto numerate and modify the XML of the schema with the data. Every terminal will have the same number that cables that are connected. Later search for implicit connections.

In a future, when QET can manage teminal strips, every time you place a terminal element, appears a contextual menu to choose at wath terminal stip is connected. It will be auto numbered as you place, and if is connected to an existing voltage, respect the numeration.

In project properties, a new tab allow manage terminals strips (add, delete, view components,...).

The same solution will be applied to cables with several wires. You need to specified cables, and when you draw a connection, specify if its a new wire of a cable.

Here is a screenshot of the result for the new script termianl block creation.

The red and blue terminals are correct processed. Fer every terminal is respected the number pole where the schema defines the connection. Every standart terminal have 2 poles (1 for the north side or 2 for the south side).

Note than now every cable of the terminal block haves a xreference.

The scripts also search for implicit connections (in green). Search conductors that have the same ''num" that any terminal and checks that its terminal_id_1 and terminal_id_2 are no connected to a terminal element. If not, is added to the terminal block. The problem is that the coordinates x and y of the conductor are peculiar. The implicit connectios ends by '#' in the terminal block.

¿Do you know how should I interpret the coord for conductors?

There is an option: count how many conductors have the same voltage. The total amount, will be assigned alternative to the Top and Bottom side in the terminal block.

To know how voltages need to count, there must be a minimum one terminal used for this voltage. The terminal block will be the sum of explicit + implicit terminals.

Possible solution for terminals connected to a common potential (bridge). You can specify the side where  the cable connected.
