Metering
Remotely, by checking the regularly uploaded files if the product configuration is correct.
On site, by passing the magnet over the product, you will hear 3 short beeps.
For the second case : When you insert a SIM CARD with pin code is 0000 used in this version (4.07.02) Downgrading to a previous version is not permitted.
The default accesses are:
Username: userhigh
Password: high
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):
Please note, all fields must be completed in accordance with the configuration of your local network.
If connecting via the GPRS network (Modem):
4/ Edit the FTP server parameters.
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:
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:
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.)
There are 2 ways of resetting the gateway.
NB : 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.
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.
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.
The average battery life is 5 years.
It may vary depending on the installation environment.
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
All our products are guaranteed for 2 years.
For further information, please see our general conditions of sale.
Files uploaded by the WebdynSun gateway are compressed in Gz format.
The data contained in these files is structured in csv format.
The data volume depends on the files exchanged.
The average is about 5 MB per month but this varies from one installation to another.
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.
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.
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.

PRODUCT END OF LIFE CYCLE
There are 2 firmware updating methods:
Local updating:
On the WebdynRF configuration interface, go to the “Actions” tab and select the updater in the “File upload” menu before clicking on the “Upload” button
Remote updating:
Upload the file containing the updater (file with extension “.bz2”) in the “BIN” directory to the FTP server . Next, place the update command in the INBOX directory corresponding to your gateway (“INBOX/”, with, the identifier of the gateway concerned)
The update command must follow the following format:
updater.tar.bz2
checksum_md5
updater.tar.bz2
checksum_md5
With:
A lack of connection to the FTP server may be due to a network connection problem (Ethernet or GPRS), an FTP login problem or a failure to initiate the connection.
If you cannot connect to the network, check the following points:
If you cannot log in, check the following points:
If the connection fails to initiate:
In this case, only the automatic connection does not work. The problem is probably caused by an incorrect schedule configuration. Please note, the schedule ID must be an integer.
For the WM-bus module data to be transmitted, you must:
A module may be defined in a unique way by all the fields below:
If a module’s data is encrypted, the encryption key for this module can be defined in the “Key” field.
To simplify the entry of the modules to be processed, a module group can be defined that conforms to the fields entered. The other fields will then be left empty (below is an example of a configuration for retrieving all Webdyn manufacturer (WDN) modules with the encryption key “00000000000000000000000000000000”.
Note: In order for the modules (filters) entered to be taken into account, the “ByPass filter” mode must be deactivated.

The tool is connected to the gateway via the installer access (install).
It is therefore necessary to use the installer password (default is “middle”), and not the administrator’s password (default is “high”)
