  • Page 14 6.7.5 When configuring the EMB HubLite to send data to the BMO site or your own data collection HUBLite , the EMB HubLite will authenticate itself with the HUBLite by using the serial number and a password. This password must be supplied here, and can be obtained when you subscribe for the BMO service, or by your database administrator.

  • Page 15: Security

    The EMB HubLite has three levels of security. These are “operator”, “user” and “admin”. When using a browser to access the EMB HubLite , basic http authentication is used to prompt your browser for a username and password. The admin account uses “admin” as the default password. To change the password, select the Accounts menu from the left side tree display.

    Click on the Modbus address number for any of the devices for specific device details. NOTE: not all Modbus devices have built in driver support in the EMB HubLite . If a device appears in the list with “Unknown” in the status column, you may need to upgrade the firmware on the EMB HubLite to access the device.
  • Page 17 Modbus/TCP connected device. See the section on manually adding a device below. Troubleshoot: The EMB HubLite will review the devices connected and offer suggestions about any problems found.
  • Page 18 8 MODBUS 8.3 Device Details The device detail page will show a list of all the pulse input data points, alarm settings and console options. The data point names for most devices are automatically entered. At the top of the page, the status of the device is shown.
  • Page 19 Alarm, or above the High Alarm levels at the time a log entry is taken, the point will be considered in an alarm state. Console: Checking this checkbox will cause the EMB HubLite to display this data point on the LCD console. Multiple data points are rotated about every 10 seconds. The values on the LCD console are updated when the next log interval occurs.
  • Page 20 Device Type: This menu will allow the selection of any built in driver or any Modbus Framework template that is available on the EMB HubLite. It is important to select the driver or template that matches the Modbus device.
  • Page 21 The Modbus setup page provides several options related to the Modbus RS485 serial port. EMB HubLite Name: This is the name of the EMB HubLite. This name will be present on all log file descriptors when uploaded to a central database website such as BMO.

    11.3 Date and Time The EMB HubLite keeps time using UTC or Universal time. All log files are recorded in UTC time as well. Timestamps shown on the EMB HubLite local configuration pages are converted to local time for the convenience of the installer.
  • Page 27 If you store data in local time, you will have the following issues. Local time is relative. Is Local the time where the EMB HubLite exists, or local to where the data is stored? If local to the EMB HubLite, you must shift each EMB HubLite data set depending on its location.
  • Page 28 This is updated ever time the modem makes a dialin or dialout connection. Time Change Log: This log contains a list of time change events.

  • Page 30: Lcd Console

    The EMB HubLite has an LCD console and two push buttons labeled “menu” and “select”. These can be used to configure some of the basic features of the EMB HubLite. The intended purpose of the console is to configure the EMB HubLite to a point where a computer can communicate with it for further detailed configuration.
  • Page 31 Note: selecting the modbus status option from the EMB HubLite console does not cause the EMB HubLite to search for new devices. The EMB HubLite checks for new devices in the background all the time, taking about 2.5 minutes to complete each pass through all 255 possible addresses. Complete each pass through all 255 possible addresses.

  • Page 32: Log File Data

    Log File Format Once you have downloaded the data from the EMB HubLite, you will need to process it. The file is an ASCII text file with comma delimited data. One line is recorded for each log cycle. The file will look something like the following example from a 4A4P-M I/O Module.
  • Page 33 This is because the 9600 baud speed of the Modbus loop is not fast enough to log all Modbus devices in less than 1 second. If a device does not respond during a log cycle, the EMB HubLite will attempt to query the device several more times.
  • Page 34 For data exported from the BMO website, the columns that are invalid (NULL) are reported as blank fields. This makes it easier to import into MS Excel as blank cells. With the current firmware, the EMB HubLite will report blank fields rather than “NULL” to make direct import of data from the EMB HubLite easier, as well as reduce the file size.
  • Page 35 files to your server, you must manually delete them. To delete log files, refer to the FTP method of downloading log files. One step detailed in the FTP section is how to delete a log file from the EMB HubLite.
  • Page 36 If all retries fail, the EMB HubLite will wait until the next scheduled upload time before trying again. • Time to wait before retry: In the event of a failure, the EMB HubLite can be configured to wait for a specified period of time before attempting another connection. This option specifies how long to wait before retrying.
