                                  All that looks OK.<\/p>Are there any messages at all in the Output.log file related to DataAccess, during the startup of the PLCnext Runtime?<\/p>The DataAccess.acf.config file should include the DataAccessLibrary.acf.config file, which should instruct the PLCnext Runtime to create an instance of your ACF component. If there is a problem creating that component instance, then there should be an error message in the Output.log file.<\/p>
                                  Are there any messages at all in the Output.log file related to DataAccess, during the startup of the PLCnext Runtime?  
                                  No, there are no logs related to DataAccess.  
                                    
                                  Isn't PLCnext Runtime automatically running when the equipment is turned on?  
                                  Is there anything I need to run separately?

                                  Even if you check with the export and echo commands, the $ARP_PROJECTS_DIR$ variable is not output.  
                                  Should I correct the $ARP_PROJECTS_DIR$ part?  
                                    
                                  Best regards.

After copying the files to the device, the PLCnext Runtime needs to be restarted in order to create the component instance.

                                  sudo /etc/init.d/plcnext restart
