Application at Runtime

When the application is running on the PLC, there are functionalities in the CODESYS development system for monitoring and changing the variable values, as well as for recording and saving their history.

There are also options to query specific information from the PLC, to view the PLC log book, to display a core dump, and to monitor the timing behavior of the tasks.

Also note the option to restrict access to the running application by means of online commands from the development system in critical states of the machine. To do this, specific system variables are available via a module of the ComponentManager library.
