Windows firewall considerations

For the Communication Driver to function correctly on a firewall-enabled computer, specific applications or port numbers must be added to the firewall exception list. By default, the Communication Driver installation program adds the required entries in the firewall exception list. If you do not want the installation program to make the entries, you can add them manually. For information on how to add the applications and port numbers to the firewall exception list, see your firewall or Windows security documentation.

Applications in Firewall Exception List

Ensure the following applications are added to the firewall exception list (either automatically during installation or manually) on the computer where the OI Server Manager is installed:

• DASWrapper.exe

• aaLogger.exe

• DASAgent.exe

• dllhost.exe

• mmc.exe

• OPCEnum.exe

• Slssvc.exe

• Asb.Watchdog.exe

• Asb.ServiceManager.exe

• Asb.Discovery.exe

• PCS.IdentityManager.Host.exe

• PCS.Portal.exe

Port Numbers in the Firewall Exception List

Ensure the following port numbers are added to the firewall exception list (either automatically during installation or manually) on the computer where the OI Server Manager is installed.

• SuiteLink:

  • TCP 5413

• OPC:

  • TCP 135 (Microsoft DCOM )

  • TCP range 49152-65535 (OPC Server-specific ports)

• PCS:

  • TCP 808 for WCF communications between PCS Clients and Communication Drivers

  • TCP 7084 for node registration

  • TCP 7085 for node pairing

  • TCP 443 for PCS clients to discover and connect to Communication Drivers

  • UDP 1900 to discover SMS nodes on the network during SMS configuration

• TCP 445 for direct TCP/IP MS Networking access

• TCP and/or UDP ports configured in the device for use with this Communication Driver. For more information, see the documentation for the specific Communication Driver.

Uninstalling the Communication Driver does not remove the firewall exception list entries. You must delete the firewall exception list entries manually. For more information, see your firewall or Windows security documentation.
