Disabling and enabling meter configuration methods

Limiting configuration methods, such as Modbus, webpages and the display, and providing read-only access reduces the attack surface.

Required for this procedure:

  • Meter connection using ION Setup.

  • Login credentials.

  • Security configuration access privileges.

  1. Open ION Setup > select the meter > Setup Assistant.
  2. Security > Security Mode > Edit. The Open Security Configuration file dialog box opens.
  3. Select the Security Configuration File (.scf) that contains the current meter settings and click Open. The Security Options dialog box opens.
    NOTE: Open the security log file to determine the .scf file you want. See “Cybersecurity configuration” for more information.
  4. On the Security Options dialog box:
    • Select or clear Web Server to enable or disable the ability to view meter settings online using webpages.
    • Select or clear Allow Web Server programming to enable or disable the ability to change meter settings using webpages.
    • Select or clear Allow Front Panel programming to enable or disable the ability to change meter settings using the display.
    • Select from the Modbus Access drop-down list:
      • None – Disables built-in Modbus map access.

      • Read/Write – Enables configuration of basic metering parameters using only Modbus communications protocol.

      • Read Only – Enables ability to read metering parameters using only Modbus communications protocol. This option is enabled by default.

  5. Click Next .
  6. Click Finish. A Confirmation message box opens.
  7. Click Yes. The Save As dialog box opens.
  8. Save the Security Configuration File (.scf) with a unique file name to avoid overwriting default Security Configuration Files.
