Application Services Host—Citect Data Platform

This section relates to how the Schneider Electric CoreServiceHost connects to Power Operation.

Use this page to link a Power Operation user name and password to be used when the Schneider Electric CoreServiceHost services connect with runtime.

Alternatively, you can use your Windows Active Directory credentials to authenticate, provided that they are associated with your Citect account. For more information on assigning roles, see Managing user accounts, roles names, and mapping.

Before you begin:

  • Add the username/password to the Power Operation project.
  • Have the project running in runtime mode.

Follow these steps:

  1. In Citect.ini, set [ctAPI] Remote = 1.
  2. Open Application Configuration Utility and then, on the left pane, click Application Services > Citect Data Platform > Connection tab.
  3. In Citect I/O Server Address choose the server address for the project that is running. If Citect requires encryption, this must be the computer name.
  4. In Citect User Name enter the user name for this user.
  5. In Citect Password enter the password for this user.
  6. Click Test Credentials to verify these credentials. If you see an error, verify the name and password, and that runtime is running, and then try again.
    When your project is running and the credentials are valid, you see Connection Successful. The user name and password can be used to connect to Power Operation.
  7. Save and click the Restart Services button.
  8. To set up web redundancy, select the Key Management tab. Use the Export Key and Import Key buttons to save an encryption key and export it to another computer as an AES file. This supports the token validation key for redundant web clients. Please keep this file secured at all times.

NOTE: To provide extra security you can run Power Operation as a service. Both Power Operation and CoreServiceHost must be running as a service on Session 0.

  1. In Citect.ini, remove [ctAPI] Remote or set it to 0.
  2. Leave Citect I/O Server Address blank.
  3. Leave Citect User Name blank.
  4. Leave Citect Password blank.
  5. Click Test Credentials, and the test will fail. However, you can verify that the service has started by viewing the Event Log.

NOTE: If unable to successfully connect to Power Operation, check the following:

  1. In Citect.ini, set [ctAPI] Remote = 1 if required.
  2. In the Power Operation Studio, confirm the Network Address 'Address' field is set to a computer name or IP Address. Localhost or 127.0.0.1 is not compatible with Citect encryption enabled.
  3. In the Power Operation Studio, confirm the Computer 'DNS Name' field is set to a computer name.
  4. Run the Computer Setup wizard and confirm the 'Network Setup' is configured properly for the system. If 'Networked' is selected, confirm the 'Address Type' and 'Address Scope' is correct.
  5. Changes to the project, ini settings, or Computer Setup Wizard requires the project to be restarted.
