Simulation library
Access
WinRelais exposes the library of simulatable components (folder D4) using three methods:
The explorer provides easy access to the blocks_simulables folder, which can be used to retrieve complete simulation subsets:
Method 1: place a symbol
Method 2: search and place a symbol
Method 3: explore and place a symbol using drag & drop
Create a symbol from an existing symbol
You can create a new symbol from an existing one, adapting its design and terminal layout as required. The new symbol inherits all the simulation logic of the parent symbol. The visual of the symbol can be defined with WinSymbol or with an image (also called texture) in png format.
Constraints :
- Pin names must not be modified.
- The number of pins may not be changed.
Example 1: We want to create a square-shaped ammeter symbol.
- Place the 'amperemeter' symbol on the folio.
- Go to Modify a Symbol and select Run WinSymbol.
- Modify the symbol as required in WinSymbol. Save modification (Ctrl-S).
- Accept the modifications.
- Save the symbol in the '_MeasuringInstruments' library, naming it 'amperemeter#carre'. (Do not use accented characters to name symbols).
It's very important to keep the same starting name, 'amperemeter' in the example, then add the '#' character followed by the name of your choice. The '#' symbol tells the simulator that the new 'carre' symbol is a variation of the 'amperemeter' symbol.
Example 2: We'd like to add a solenoid valve symbol to the family, which we'll call 'Solenoid_Valve#1'.
The operation takes longer than in the previous example, as the symbol's drawing must be created when it is active. Active symbol drawings are stored in the file : C:\Users\Public\Documents\Elec-CAO\wrs-data\wrs-on-symbols.xrs
- Place the 'Solenoid_Valve' symbol from the '_Coils' family on the folio.
- Modify the symbol as described in points 2.3 and 4 of example 1.
- Save the symbol in the ''_Coils'' library, naming it 'Solenoid_Valve#1'.
- Open the schematic 'wrs-on-symbols.xrs' in WinRelais. Preferably select the '_Coils' folio.
- Place the newly saved symbol 'Solenoid_Valve#1' on the folio.
- Go to Modify Symbol.
- Modify the symbol as required in WinSymbol. Save modification (Ctrl-S).
- Accept the modifications.
- Save schematic as 'wrs-on-symbols.xrs'.
Example 3: Using a png image to create the visual for a solenoid valve, which will be named 'Solenoid_Valve#2'.
We may find that WinSymbol's drawing capabilities are not sufficient to create the visuals for the symbols. In this case, it's possible to use a texture that will be edited in a separate program. The visual of the initial 'electrovalve' object manipulated earlier is constructed with this texture:
The texture must have the same name as the object.
- Place the 'Solenoid_Valve' symbol of the '_Coils' family on the folio.
- Save the symbol in the ''_Coils' library, naming it 'Solenoid_Valve#2'.
- Access the 'Solenoid_Valve.png' texture in the folder: C:\Us\Public\Documents\Elec-CAO\wrs-data\sym_textures\_Coils\Solenoid_Valve.png
- Copy the texture renamed to 'Solenoid_Valve#2.png' into the same folder.
- Edit the 'Solenoid_Valve#2.png' texture in a suitable program (e.g. GIMP) as required, then save (command 'Overwrite Solenoid_Valve#2.png' with GIMP).
