AN 191 Double Bridging Application<\/h2>\n\n\n\n

General description of modbus bridge<\/h3>\n\n\n\n

The need to collect data from machines or electrical panels located within a factory or commercial complex is increasingly frequent. Very often, however, an ad-hoc connection must be installed (ethernet<\/a>, serial, power supply). Thanks to the MDB-W converter it is now possible to use both the WiFi network and an existing Ethernet network as a vehicle for data transport.<\/p>\n\n\n\n

In the case above, the MDB-E modbus bridge has been used for the Ethernet communication, which is an Ethernet – serial RS232 \/ RS485 converter. While the MDB-W modbus bridge has been used for WiFi communication, as it is a WiFi serial RS232 \/ RS485 converter.<\/p>\n\n\n\n

Let’s see them in detail:<\/p>\n\n\n\n

  1. MDB-E<\/a><\/mark><\/strong> works independently from the protocol by connecting all the protocols based on TCP \/ IP with the serial ones in a completely transparent way. It allows all devices equipped with a serial port to communicate with software or cards based on Ethernet communication.<\/li>
  2. MDB-W<\/a><\/mark><\/strong> allows serial devices to communicate with IP devices transparently via WiFi network. It allows all devices equipped with a serial port to communicate with software or cards based on IP communication and sharing a LAN with WiFi.<\/li><\/ol>\n\n\n\n

    Modbus bridge application<\/h2>\n\n\n\n

    4neXt MDB bridges are able to send packets to any node on the network and convert them again to reach the desired node.<\/p>\n\n\n\n

    Here is a classic example in which a ModBus RTU Master must reach a ModBus RTU Slave in a very remote site of a LAN or Intranet.<\/p>\n\n\n\n

    Implementation<\/h2>\n\n\n\n

    As shown in the layout image above, it is possible to obtain this functionality using two MDB bridges, in this case we used an MDB-E on the master side and an MDB-W (WiFi) on the Slave side. Note that any MDB-E (Ethernet) or MDB-W (WiFi) combination can be used.<\/p>\n\n\n\n

    Benefits of the modbus bridge<\/h2>\n\n\n\n

    The main advantages that can be obtained are:<\/p>\n\n\n\n

    • To reach each node using the WiFi network or the Ethernet network without distinction and to facilitate and streamline communication within a network.<\/li>
    • Easy installation thanks to the versatility of the bridge.<\/li><\/ul>\n","protected":false},"excerpt":{"rendered":"
