    HW group Adding connected meters and measured values Start the WWW interface of HWg-PWR and go to the Device menu. The list of detected meters is empty. Individual meters are always added to HWg-PWR manually. A tool for automatic discovery of meter addresses is also available in the Mbus Scan submenu (only finds meter addresses, does not add them to the system): www.HW-group.com...

  • Page 12: Automatic Discovery Of Meters

    HWg-PWR: M-Bus IP energy meter (SNMP, WEB) HW group Automatic discovery of meters: 1. At the Device Base Parameters page, fill in the M-Bus Scan section: Address – Range of M-Bus addresses where the meters can be discovered. The default is 0-252; however, a smaller range can speed up the discovery process significantly.
  • Page 13 5. Write down the addresses of discovered devices and return to the Device page. Note: If HWg-PWR does not find any connected meters, re-check the M-Bus connection (in particular its polarity) and the baudrate and parity configuration, or try to look up these values in the documentation of your meter.

  • Page 18: General Setup Tab

    Base section Device Name – Custom name of the HWg-PWR device in order to distinguish multiple HWg-PWR units in a network. The device name can be up to 16 characters long. WWW Info Text – Custom text in the WWW interface footer. Useful for contact information about the operator of that particular HWg-PWR, if the device is accessible on a public IP.
  • Page 19 HTTP Port – Port number where the built-in WWW server listens. Changing the port number is useful in situations where multiple HWg-PWR units need to be accessible from an external network through a router. Ask your network administrator if or whether you need to change this value. The default port is 80.

  • Page 20: Snmp Tab

    SNMP port – Port number for SNMP communication. The default is 161. SNMP Access section Community – Name of the SNMP community for accessing HWg-PWR over SNMP. Two communities can be defined. Each Community can have the following permissions defined:...

  • Page 21: E-Mail Tab

    Password – Password for authentication to the SMTP server. If the Authentication box is not checked, this field is irrelevant. FROM – E-mail address of the sender, that is, the HWg-PWR unit. The address may be necessary for the SMTP server and it can be used to identify the HWg- PWR unit, or for filtering and further processing of alarm messages.

  • Page 22: Time Tab

    SNTP Server – IP address or host name of the time synchronization server. Default is time.nist.gov. Time Zone – Timezone where HWg-PWR is located. Used to set correct system time. Necessary for correct logging of measured values. Summertime – Enables daylight savings time. Used to set correct system time.
