After the boot procedure the login screen appears on the display. The WebLog can be operated either by the touchscreen on the device or a web browser (e.g. Firefox) using the network interface.
WEBLOG 250 You can switch the virtual keyboard to a second layer by clicking on the shift symbol (up arrow left to the “z”). This layer basically contains the capitals and some more special characters. The backspace key is on both layers in the upper right corner of the key panel. After the user has clicked on “Login” the WebLog checks the password. The administrator will see the main menu after a successful login.
WEBLOG 250 4.1.1 Important system settings You should now make some important system settings to complete the initial setup. Please enter the submenu “System settings” by clicking on the respective button. Note: The button “factory reset” is not available in the web browser. First perfom the network configuration (button “Ethernet”) so that the WebLog can be alternatively operated by a browser and export targets for the logged data via FTP or email become available.
WEBLOG 250 You can select a fixed IP address or dynamic IP address which will be assigned by a DHCP server. You can ask your network administrator for a fixed IP address. This allows your web browser to always access the WebLog at the same, known IP address (e.g. the URL address for above setting is: http://192.168.1.85). In most cases the gateway address has to be set to the IP adress of the DSL router. The router can enable an external access by internet to the WebLog by using port forwarding.
WEBLOG 250 If the WebLog contains an optional WIFI module, the signal quality (0 to 100%) is shown in the wireless information area. A web browser can access the WebLog via network after the network configuration has been done correctly. From this point you can continue the configuration using a web browser (e.g. Firefox).
WEBLOG 250 The button “MBus Settings” leads to the settings of the serial M-Bus interface and global definition of default values for basic M-Bus units. The Logger ID is used as a site / plant description and to identify of the export files. The master-device for the internal M-Bus level converter is “/dev/ttyAPP0“. The default baudrate for the M-Bus meters is in general 2400 baud, but some old meters only support 300 baud. There are also meters communicating additionally with 9600 Baud.
WEBLOG 250 The button “MBus Info” gives an overview of the M-Bus voltages and other properties. The total M-Bus current shall be about the number of meters multiplied by one unit load (1.5 mA). Some meters may consume more than one unit load. A state of “warning current” or “overcurrent” will be shown in the field „M-Bus Status“ and in the LED´s. 4.1.3 Search for meters The meter list can be accessed from the main menu by clicking the button “Meters”.
WEBLOG 250 First you specify whether the search shall be done by primary or secondary addressing. There is a fast method and an intensive method with more retries and more tolerant timing (slowly but safer in case of wide M-Bus networks with many meters). If the installed M-Bus meters have not been programmed with a unique primary address, you must perform a search for secondary addresses. The progress of the search for meters is displayed in a window.
WEBLOG 250 The selection of a single meter by touch or click opens a detailed view for that meter with the two tabs “Parameter” and “Values“. You can enter free text into the fields „Text 1“ and „Text 2“ to add a detailed description for that meter. The meter can be assigned to a group or tenant with the drop down box “Group”. One of the predefined log intervals for automatic logging of this meter can be selected with the field “Loginterval”.
WEBLOG 250 4.1.4 Filter meter view There may often be the requirement to reduce the meter entries shown in the list of meters to meters with special criteria. The possible criteria are for example: Meter type (medium e.g. electricity meter) Meters of a selected manufacturer Meters of a selected primary address range The filter view is envoked from the context menu in the lower left corner of the status line by the menu entry “Filter Meter”.
WEBLOG 250 “Save” additionally stores the new filter with a name. A stored filter can be used again later or utilized during definition of exports. “Apply” uses the filter to temporary reduce the view to the list of meters. Only the electricity meters are displayed in the following example. The title line shows additional information about the filter ([name] [no. of displayed meters / no. of total meters without filter]. “Erase” removes the filter.
WEBLOG 250 The second example shows an hourly log interval. The logging is done every full hour. The created log intervals can be individually assigned to the meters (Meters → Parameter → Log interval). In most cases all meters shall get the same log interval. This can be done in one step. Please open the context menu in the list of meters view and start the menu “Edit Meters” This opens a new window “Parameter” with wildcard entries.
WEBLOG 250 4.1.6 User groups The user groups are configured in the submenu “Users” within the menu “Logger Settings”. The user “Admin” with the highest rights is already predefined.The administrator can add new users for example tenants, which is the role with the lowest rights. User belonging to the group of inspectors are able to read all meters from the tenants and can use predefined exports of the administrator. The tenants only see their own meters and have no rights to generate or start exports.
WEBLOG 250 4.1.7 Export setup Exports are used to transfer meter data, which have been logged for a specific time interval, to a USB memory stick, to an FTP server or to an e-mail address. You can access the exports submenu by using the button “Exports” in the main menu. The button “M-Bus Export Settings” opens a dialog where you can select in the sheet “format” the decimal delimiter for numbers, which can be either a “comma” or a “point / dot”.
WEBLOG 250 In the sheet “Export Filter” you can set the maximum numbers for the data in the exports by defining the maximum storage number, the maximum tariff number and the maximum subdevice to be included in the export files. The default value for the storage number is 1, which implies that only data with storage number 0 (actual value) and 1 (normally the yearly due-date value) are exported. The default value for tariff is 3 and for subdevice it is 2.
WEBLOG 250 If you start an export manually by the button “Run” you can either export the logged data from the database (Export from Database) or perform a direct (immediate) readout of all meters (Direct Export) with a following export of the actual data. The following steps describe the manual export from the data base: A calendar view appears where you can select the start and end time point for the logged data which shall be exported.
WEBLOG 250 The next step is the definition of the export target (USB memory stick, FTP server or e-mail address). You have to enter the destination e-mail address and the SMTP server in case of an e-mail transfer. If you want to use your internal Microsoft exchange server, please enter the IP address of that server and the exchange user with password. The encryption type for MS Exchange is “Plain” (unencrypted).The example shows the settings for a GMX account using the GMX SMTP server.
WEBLOG 250 The export to a FTP server requires settings for the URL of the FTP server, the user name and the respective password. Port 21 is used for the FTP service by default, but can be changed if required. There is an additional input line for the destination subdirectory on the server. A notify window (“Exporting data”) pops up during the running export to a FTP server and during transmit of data by e-mail. 10/2021 · User Manual Version 1.0 · valid from firmware version 3.1.
