    There are two types of configuration: via the web interface or via SMS.

    Configuration of the web interface :
    1/  Go to the configuration page with the gateway IP address (default 192.168.1.12)
    2/  Go to the Configuration tab.
    3/  Select either the Ethernet or modem connection mode:

    If connecting via the local network (Ethernet):
    – Edit the WebdynSun’s IP parameters by assigning it a network-compatible address.
    Please note, all fields must be completed in accordance with the configuration of your local network.

    5/ Confirm the changes.
    6/ Restart the WebdynSun gateway using the new settings.
    7/ In the menu, click on the “installation” tab, followed by the “connection” sub-tab and start the connection

    Configuration via SMS :

    This configuration method requires the use of an active SIM card with a data option and a pin code that must be either “0000” or disabled.
    The SIM card must be inserted into the unit before connection to the mains supply.
    After connection to the mains supply, send the following SMS messages to the number of the previously inserted SIM card:

    SMS for configuring the APN:
    After replacing the generic fields with those of your operator, send the following SMS*:

    apn=apn_name;usr=user_name;pwd=password;

    Replace the above SMS fields with the following information:
    – apn_name: APN name supplied by your mobile operator
    – user_name: APN ID supplied by your mobile operator
    – password: APN password supplied by your mobile operator

    SMS for FTP configuration:

    After replacing the generic fields with those of your FTP server, send the following SMS*:
    Ftp=server_name:user_name:password:port;

    Replace the above SMS fields with the following information:
    – server_name: FTP server address
    – user_name: FTP account ID
    – Password: FTP account password
    – Port: FTP server port (the default port is 21)

    Connection SMS :
    Send the word “connect” by SMS* to launch a connection to the FTP server

    *Please note: the formatting of the SMS must be exactly identical to that shown above (e.g:no spaces between characters, etc.

General use of the WebdynSun gateway

  1. How do I reset the gateway?

    There are 2 ways of resetting the gateway.

     If connecting by Ethernet:

    • Disconnect from the mains
    • Remove the cover
    • Disconnect the battery
    • Put the DIP Switch 2 on the WebdynSun card in “ON” position
    • Start the WebdynSun by connecting it only to the mains power supply
    • Wait until all the LEDs flash and then stop flashing (3 to 5 mins).
    • Disconnect from the mains
    • Reset the Dip Switch 2 to “OFF” 
    • Reconnect the battery
    • Reconnect to the mains supply and the WebdynSun starts normally.

    – If there is a SIM card inserted in the unit:

    • Send an SMS message containing the word “factory” to the number of the inserted SIM card.
    N.B. : Resetting the gateway restores the configuration to its original state. Please note: data will be saved but the specific settings will not. Therefore, all the settings must be reconfigured
  2. Can the gateway send commands to connected devices?

    Commands can be sent to connected devices with the exception of certain inverters and Modbus slaves that do not accept write requests.
    If the device allows it, command files can be created on the FTP server.

  3. How long can data be stored for?

    The WebdynSun has a memory of about 100MB.
    Therefore, if the remote server cannot be accessed, the WebdynSun gateway can backup data for several months.
    The maximum data backup time varies depending on the amount of data to be collected.
    The average backup time ranges from 3 to 4 months.

  4. What is the battery life?

    The average battery life is 5 years.
    It may vary depending on the installation environment.

  5. Can data be sent to a PLC?

    Yes, data may be sent to a PLC if the latter is equipped with a Modbus protocol.
    The “Report” configuration file allows the WebdynSun gateway to automatically write the values read on a Modbus slave

  6. What are the warranty conditions?

    All our products are guaranteed for 2 years.
    For further information, please see our general conditions of sale.

  7. What format is used for the data files?

    Files uploaded by the WebdynSun gateway are compressed in Gz format.
    The data contained in these files is structured in csv format.

  8. What data volume is exchanged in GPRS?

    The data volume depends on the files exchanged.
    The average is about 5 MB per month but this varies from one installation to another.

Inverter compatibility with the WebdynSun gateway

  1. Can I connect several different brands of inverter on the same gateway?

    Different brands of inverter may be connected to the RS485(B) port or via the Ethernet port if the inverter protocol is based on the Modbus protocol (RTU or TCP).
    However, different brands of inverters cannot be connected to the same RS485(A) port.

  2. Which inverters are compatible?

    For a list of compatible inverters, please see the product page of the WebdynSun gateway

  3. What if the inverters are not detected?

    – Check if the correct inverter protocol is selected before starting detection:
    protocole_onduleur– Check the wiring and configuration of the inverters by referring to the inverter appendices.
    – Check that the inverters are not in OFF or stand-by mode.
    – Check that the line end plugs on the RS 485(A) Bus are turned on.

Compatibility Modbus devices

  1. Must I configure the Modbus device before connecting it?

    Yes, any device you wish to connect must be configured and its Modbus definition file must be created.
    The configuration is mainly based on the RS485 serial bus parameters and the IP parameters.

  2. Can I connect different Modbus devices on the same RS485 (B) port?

    Yes, different Modbus devices can be connected to the same RS485 (B) port.
    However, they must have the same communication parameters (bus parameters or compatible IP parameters), in order for them to communicate with each other.

Compatibility with TIC is not detected

  1. What if my TIC meter is not detected?
    • Check that it has a TIC output
    • Use a twisted shielded pair cable for the wiring
    • Check that the TIC output is enabled on the meter
    • For PME/PMI meters, check the speed of the TIC flow
    • For Landis+Gyr L18C5 meters, check the consistency of the outgoing TIC flow
    • For Schlumberger yellow tariff meters, add a resistance of between 200 and 300 Ohms between the TIC input terminals and the WebdynSun.
  2. Which TIC meters are compatible?
    • “Bleu” electronic single-phase multi-tariff meter (CBEMM)
    • “Bleu” electronic single-phase multi-tariff meter (CBEMM – ICC version)
    • “Bleu” electronic three-phase multi-tariff meter (CBETM)
    • “Jaune” electronic meter (CJE)
    • “Interface Clientèle Emeraude” meter (ICE)
    • “Interface Clientèle Emeraude à quatre quadrants” meter (ICE-4Q)
    • “PME-PMI” meter
