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 the .xml symbol table created in Codesys along with your application.
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.
