ISPSoft 3.14 is the latest version of Delta PLC programming software (until now). When we work on a project we need to work with variables. With a big project, the variables (symbols) are very much and managing or debugging the program with the symbols is a burden for the programmer.
In this post, we share a method to create and manage the symbol table (variables) by using the “Export and Import Symbol” functions.
ISPSoft – Local Symbol and Global Symbol table
On Delta ISPSoft we have two types of symbol tables the local symbol and the global symbol.
- The global symbols: It can be used in all the POUs in a project, we can access the global symbol by clicking on the “Project tree” -> “Global symbols”.
- The local symbols: It can only be used in the POU in which the local symbols are declared. We can see the local symbol table in a POU at the top of the window for the POU. And the label of a local symbol in a POU can be the same as the label of a local symbol in another POU.
- However, if the label of a local symbol declared is the same as the label of a global symbol, ISPSoft will automatically regard the local symbol declared in a POU as a local symbol.
Add the variables to the symbol table
Software use:
- Delta ISPSoft 3.14.01
- Microsoft Office – Excel
We can be using this method for the local symbol and global symbol table. In this post, we make it on the local symbol table. Follow the below steps:
- Open ISPSoft and create a project, click on “Project tree” -> “Programs” and add a POU.
- Right-click on “Local symbols” (at the top of the program window) -> “Add a symbol” and enter the information of the symbol.
- Right-click on the symbol added. Select “Export Local Symbol”, enter the file name and select the folder to save the file. Click “Save” we have a “*.csv” file.
- Open the “*.csv” file above with Microsoft Excel”. And then add all symbols for the POU by entering the information for all columns, saving the file and closing Microsoft Excel.
- Require: Class, Identifiers, Address, Type columns
- Optional: Initial Value and Comment columns
- Back to “ISPSoft”, right-click on the symbol added. Select “Import Local Symbol” and browse to the “*.csv” file edited. Tick on “Yes” for “Clear table before importing”. Click “OK”.
- Now all symbols added to the local symbol are easy and quick. You can try this method with a real Delta PLC or use simulator mode on ISPSoft.

Summary
Hope that with the above method, you can easily manage all variables for your project on ISPSoft. It is helpful when we use a Delta HMI connect to the Delta PLC also. In the next post, we will use the “*.csv” file exported from ISP Soft for programming the HMI on DOPSoft.
