Application and access possibilities Browser access With password protected access the status of Input, Counter and Output can be monitored in the browser. You can also switch the output with the required access rights. -
Page 30: Rest
Product Introduction REST REST (Representational State Transfer) is another Web-based protocol that can be used to integrate the Web-IO into the environment of Industry 4.0 and the Internet of Things. Web-API - HTTP-Requests/AJAX The status of Input, Counter and Output can be queried using HTTP requests. -
Page 31: Actions
Product Introduction Actions Depending on predefined events on the IOs, the Web-IO can initiate actions such as sending an email message. Other actions include sensing syslog messages or SNMP traps, writing to a file via FTP , sending data via TCP or UDP , or switching its own output. -
Page 32: Startup
Startup 5. Startup Once the Web-IO has been properly installed and wired, the power can be turned on. All three status LEDs should come on briefly. After approx. 5 seconds only the Power LED should remain on. The Status LED may flash. If a valid signal is detected on one of the inputs, the corresponding LED will come on. -
Page 33: Changing The Set Ip Parameters
Startup Netzwerke ohne DHCP Install the Wutility Windows PC program (download at http:// www.WuT.de). If no Windows PC is available, see the Appendix, sub-section Alternatives to IP Address Assignment. When Wutility is started the local subnet is searched and all found W&T network components are listed. -
Page 34: Basic Settings
Basic Settings 6. Basic Settings The rest of the Web-IO configuration is done in the browser. As an address enter the IP address of the Web-IO. Click on Login in the navigation tree and select Administrator as the user. By default no password is assigned, you need only click on the Login button to configure the Web-IO with Administrator rights. -
Page 35: Date / Time
Basic Settings Pulse mode By enabling Pulse mode, when the Output is switched to the ON state it reverts automatically back to the OFF state after the set pulse duration. When turned on again during the pulse, the pulse duration begins to count over again. Reset allowed means the Output may also be switched to the OFF state during a pulse. -
Page 36: Basic Applications
Basic Applications 7 . Basic Applications The Web-IO features a variety of different communication options supports various standard protocols. We recommend enabling only the communication paths actually required in your application. This limits the possibility of unauthorized access and manipulation.

Page 40: Box-To-Box
Basic Applications Box-to-Box Box-to-Box mode links two Web-IOs to each other over the same network so that the output of the one Web-IO follows the input of the other Web-IO (ON on the input of Web-IO A switches the output of Web-IO B to ON). Box-to-Box mode the idea is to configure one Web-IO as the master and the other as a slave. -

Page 55: Email Message
Actions For text messages not only the actual message sent when initiating, but also a Clear message can be stored. The Clear message is sent when the initiator for the action is no longer active – i.e. the normal state is resumed. Sending of messages takes different amounts of time depending on the protocol. -

Page 60: Binary Structures Binary
Access from your own applications If the Web-IO receives no valid command within 30 seconds, it closes the connection and is then free again to open a new connection. The Web-IO behaves the same way when a defective or unknown command is received. Reading the input is generally done by polling. -
Page 61: Http Request
Access from your own applications A detailed description of the supported HTTP binary structures and more details about access using BINARY sockets can be found in the Web-IO programming manual (download at http://www.WuT. de). Follow the Manual link on the data sheet page of your Web-IO. HTTP request In addition to traditional socket accesses the Web-IO can also be addressed directly via HTTP using HTTP requests. -
