  • Page 3: Introduction

    W&T Introduction The W&T Web-IO Analog-In models incorporate all the functions in one box for capturing, storing and displaying your analog measurements (0...20mA or 0...10V). A variety of alarm functions is also available which can be custom implemented in your own applications or in existing systems. This manual contains all the information you need for installing, configuring and operating the Web-IO Analog-In module.

  • Page 8: Assigning The Ip Address Using „Wutility

    W&T 1.3 Assigning the IP address using „WuTility“ Once the hardware has been connected to the supply voltage as described above, you must assign the IP address needed for operation in a TCP/IP network. You can obtain the correct value for this parameter from your system administrator.
  • Page 9 W&T Click on the „IP address“ symbol: In the resulting window enter the desired network parameters for the device and confirm by clicking on „Continue“. The BOOTP client of the Web-IO Analog-In can be activated in the following window. Clicking on the Continue button assigns the network parameters to the Web-IO Analog-In.

  • Page 10: Ip Assignment Using Dhcp Protocol

    W&T 1.4 IP assignment using DHCP protocol Many networks use DHCY (Dynamic Host Configuration Protocol) or its predecessor BOOTP described in the following section for centralized, dynamic assignment of network parameters. By default DHCP protocol is activated, so that in network environments with dynamic IP assignment you only need to connect the Web-IO Analog-In to the network.

  • Page 11: System Name

    W&T In the following dialog window deactivate the options BOOTP and DHCP. Click on Next to send the new configuration data to the Web-IO Analog-In. • Web Based Management In Config r Device r Basic Settings r Network you can alternately activate or deactivate both the protocols.

  • Page 12: Lease Time

    W&T 1.4.3 Lease time The lease time determined and sent by the DHCP server specifies how long the IP address will remain in use. After half the lease time has expired the Web-IO Analog-In attempts to extend the time for the assigning DHCP server and to update the address.

  • Page 13: Reserved Ip Addresses

    W&T 1.4.4 Reserved IP addresses The Web-IO Analog-In provides services which can make use of other clients in the network as needed. To open a connection they of course need the current IP address of the Web-IO Ana- log-In, so that in these applications it makes sense to reserve a particular IP address for the Web-IO Analog-In on the DHCP server.

    W&T 7 Appendix 7.1 Alternate IP address assignment 7.1.1 Using DHCP-/BOOTP protocol Many networks use DHCP (Dynamic Host Configuration Protocol) or BOOTP for centralized and dynamic assigning of the IP addresses. It makes no difference to the Web-IO devices which of the two protocols is used in any given case, since DHCP is simply a downward compatible extension of BOOTP.
  • Page 69 W&T Please consult your system administrator when starting up the device in DHCP/BOOTP networks. If the address is assigned using DHCP, you must also indicate that a reserved IP address is required. To integrate this into the respective address database, the administrator needs the Ethernet address of the device, which can be found on the housing sticker.
