Configuring Modbus TCP/IP filtering using the webpages

You can configure access rights for any valid IPv4 or IPv6 address, plus any anonymous IP addresses.

Prerequisites:

  • Refer to Restoration of temporarily disabled configuration settings in webpages to know availability of these features on your meter model.

  • IPv6 support is available only in PM5560 / PM5563 / PM5580 meter models with firmware version 4.5.0 or later.

  • IPv4 and IPv6 address. If you do not have these details, contact your local network administrator.

  • Login credentials for the webpages.

To configure Modbus TCP/IP filtering using the webpages:

  1. Login to the meter webpages.
  2. Based on your meter firmware version, click Settings > Modbus TCP/IP filtering OR click Settings > Communication > IP filtering.
  3. Click Enable Filtering to enable Modbus TCP/IP filtering.

    The IP address fields become editable, except for the anonymous IP address field, which is indicated by asterisks (***.***.***.***).

  4. Set the access for anonymous IP addresses.
    NOTE: If Modbus TCP/ IP filtering is enabled, anonymous IP addresses can only have read-only or no access; they cannot have full access.
  5. Enter the additional IP addresses (IPv4 or IPv6) that you can access the meter and any downstream serial devices.
    NOTE: The filtering behavior depends on the internet protocol mode you configure:
    • Enable IPv4: Only IPv4 filtering is applied.

    • Enable IPv6: Only IPv6 filtering is applied.

    • Both Enable IPv4 and Enable IPv6: Both IPv4 and IPv6 filtering are applied.

  6. Set the access level for each specified IPv4 or IPv6 address.
    NOTE: If duplicate IP addresses are entered, the second listing and its access level are discarded when you save the changes.
