4.6  Gateway: Restart 
For changes of the configuration files to be activated, restart the gateway. 
If changes are made in the “pnet1.cfg” PROFINET driver file, a complete restart 
(de-energized) of the gateway is required. 
 
Table 4-10: Restarting the gateway 
Click the “Restart required!” button. 
 
Alternative: 
To restart the gateway, navigate to the 
“General > Restart > Restart” menu item. 
 
The gateway automatically checks the 
configuration files and, in the “Configuration 
check” tab, displays errors and warnings and 
the specific file and line where the cause can 
be found.  
Check the appropriate files/lines. 
If the current configuration in the gateway is 
correct, click “Next”. 
Go to the “Restart Gateway” tab. 
Optionally, you can check the “complete 
system restart” check box to perform a 
complete system restart.  
Click the “Restart” button to confirm the action 
and follow the menu prompts. 
After the restart, the changes made are 
activated. 
 
Note 
After a complete system restart, you have to 
log back on to the gateway.
