Secure by default: Configuring PLCnext Store

PLCnext Store and NTP server

A connection to the PLCnext Store can only be established with the current time.
In the security context, you can only establish a reliable connection to the PLCnext Store if an NTP server is available. See also Configuring the system time  in this PLCnext Technology ‑ Security Info Center and System time in the main PLCnext Technology ‑ Info Center.

Adding the firewall rules

For a successful connection, you must add the appropriate firewall rules.

Prerequisites: 

  • There must be an Ethernet connection to the Internet with a corresponding IP address in accordance with the security context (see Deriving IP addresses).
  • The device must be added to the PLCnext Store.

To add the firewall rules, proceed as follows:

  • Open the Firewall page (Security → Firewall) in the WBM. 
  • Open the IP INPUT RULES tab.
  • Provide the following information:
  • Click the SAVE & APPLY PAGE button.
  • Open the IP OUTPUT RULES tab.
  • Provide the following information:
  • Click the SAVE & APPLY PAGE button.

Activating PLCnext Store on the PLCnext Store page

  • Open the PLCnext Store page (Configuration → PLCnext Store) in the WBM. 
  • Activate the toggle switch of the PLCnext Store Service .

The PLCnext Store status should now look like this: 

 

If there are connection problems, go to the PLCnext Store and check that the device is correctly added and connected. You can find information on this in the PLCnext Store Info Center.

Restore PLCnext Store connection after reset

After resetting the controller to reset type 1 or 2, the PLCnext Store is no longer accessible (No registration token available). 

To reset the device communication, proceed as follows:

  • Log in to the PLCnext Store, using your PLCnext Store account credentials.
  • Open your device list.
  • Select the device you want to put back online.
  • Click the More button. 
  • Chose Reset Device Communication.

    This will automatically create a new security token for your device. This security token is automatically stored in the device and authenticates you as an authorized user.
