Error:

"The selected controller profile does not match that of the target system..."

Check that the target system entered in the target system settings (Resources) matches the parameters entered in 'Online' 'Communications parameters'.

Error:

"Communication error. Log-out has occurred"

Check whether the controller is running. Check whether the parameters entered in 'Online' 'Communications parameters' match those of your controller. In particular, you should check whether the correct port has been entered and whether the baud rates in the controller and the programming system match. If the gateway server is used, check whether the correct channel is set.

Error:

"The program has been modified! Should the new program be loaded?"

The project which is open in the editor is incompatible with the program currently found in the PLC (or with the simulation mode program being run⮫ “'Online' 'Simulation'”). Monitoring and debugging is therefore not possible⮫ “Debugging”. You can either choose "No," logout, and open the right project, or use "Yes" to load the current project in the PLC.

Message:

"The program has been changed. Load changes? (ONLINE CHANGE)".

The project is running on the controller. The target system supports 'Online Change' and the project has been altered on the controller with respect to the most recent download or the most recent Online Change. You may now decide whether these changes should be loaded with the controller program running or whether the command should be cancelled. You can also, however, load the entire compiled code by selecting the Load all button.
