The Service Tool allows monitoring variables in live mode using a CAN connection through the E-Com USB/CAN adapter cable. All that is needed is to include and install the .xml symbol table created in Codesys along with your application installation.
Once the symbol table is installed onto the controller, every time you connect to it thereafter with the service tool you will be able to monitor all the variables included in the symbol file. The end customer will not need access to any of the source files.
See full instructions on programming the uCOntrol using the service tool.
Step 1 - Create the Symbol Tables
Add the Symbol Configuration Object to your Codesys project then check off each variable you wish to monitor. Build the project to generate the .xml symbol table.
Step 2 - Load the application and Symbol Table
Step 3 - Start Monitoring
As soon as the application and symbol table have been successfully loaded on the uControl the Service Tool will automatically go into live mode and display the current value of the variables. The controls allow you to start and stop monitoring. The variable names and their values will appear in the main window.
Close all off your tools down and restart the Service Tool and you will see the variables and their status appear on the main page, no file loading is needed.
