Change the connection settings of the GPRS modem to the settings provided by your mobile operator.Ħ/ Restart the WebdynSun gateway using the new settings.ħ/ In the menu, click on the “installation” tab, followed by the “connection” sub-tab and start the connection.If connecting via the GPRS network (Modem): Please note, all fields must be completed in accordance with the configuration of your local network. Edit the WebdynSun’s IP parameters by assigning it a network-compatible address.If connecting via the local network (Ethernet): There are two types of configuration: via the web interface or via SMS.ġ/ Go to the configuration page with the gateway IP address (default 192.168.1.12)ģ/ Select either the Ethernet or modem connection mode: Connect: to launch the connection to the FTP server and load the configuration ( see section 3.1 : “ “connect” connection command.Ftp: to configure the FTP server that will contain the concentration configuration ( see section 3.3 : “ “ftp” FTP configuration command”).(see section 3.2: “ “apn” modem configuration command ) Text message configuration requires sending the following commands: See section 3.1.2 : “ Configuration files ” for more details. The other fields can be left at the default values subject to the directories having been properly created beforehand. Therefore the following fields need to be configured: “Interface”, “Type”, “Server type”, “Address”, “Port”, “Login” and “Password”. The parameters for the servers to be configured are at least the following: This configuration is done from the “Modem” configuration page ( see section 3.2.2.4 : “ Modem ”).
This configuration is done from the “Networks” configuration page ( see section 3.2.2.3 : “ Networks ”).įor a modem connection, the modem configuration must be correct before a connection can be set up. For an ethernet connection, the configuration must be compatible with the concentrator’s local network topology so that it can access the servers. Start by establishing a connection to the concentrator by connecting to it to access the server configuration:Įnter the “ethernet” or “modem” connection type:įor an ethernet configuration, make sure the IP parameters are compatible with server access according to the concentrator local network configuration. There are two configuration solutions, using the web interface and using text messages: Its very easy to deploy Modbus data gateway guarantees reliable and effective supervision of slave installations that dialogue in RTU (wired bus) or TCP (Ethernet) mode. Specialised in M2M for the energy sector, France’s Webdyn has been offering a wide range of solutions to allow industrial and network equipment to communicate for over 20 years. Known as “Cycle Redundancy Check”, it covers the entire message (recipient, function, address and number of words to read) thereby providing exchange reliability close to 100 %. In its modes widely used in industry, Modbus has a native frame error checking code.
A protocol renowned for its high reliability
The control or collection gateway often has radio transmission (GPRS, etc.) to the establishment’s information system. For TCP/IP, the recommended connectors are RJ 45 or IP 65.
#MODBUS RTU OVER TCP SERIAL#
In an RTU configuration, only one serial port or cabled bus connection compatible with the RS-422 or RS-485 standards is required between the installation and the controller. The technical deployment of the Modbus ecosystem stands out by its simplicity. Its TCP/IP version offers speeds of 10 to 100 Mbits/second (and almost unlimited connectivity) on classic network topology such as ring or star. Simple but efficient technical architectureīased on master-slave architecture, Modbus offers high operational flexibility Its serial RTU mode speeds up data exchanges with its 8 bit encoding while allowing the connection (with repeaters) of 247 peripherals over a distance of 1200 metres. Its simple architecture, easy integration and high reliability are ideal to efficiently control or take remote readings from automated equipment. Modbus, which appeared in the 1970s, is an unavoidable communication protocol for wired M2M for industry, construction and energy.
