Application in Runtime Mode

When the application is running on the PLC, in the CODESYS Development System there are some features for monitoring and changing the values of the variables as well as for recording and storing the value charts.

Furthermore, you can poll some information from the PLC, you can have a look into the PLC-log, display a core dump and monitor the time behaviour of the tasks.

Regard also the possibility to restrict the access on the running application in critical states of the machine via online commands provided by CODESYS Development System. For this purpose some system variables are available in a module of the ComponentManager library.
