IO channels that are configured as outputs are also supplied via VDD. The loads to be switched must also be taken into account in the current consumption. Input wiring Each of the four IO channels has a plus and a minus terminal.

Page 25: Initial Start-Up
Inbetriebnahme 6. Initial start-up After the Web-IO has been properly installed and wired, the power supply can be switched on. All three status LEDs should light up 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 also lights up. -
Page 26: Changing The Set Ip Parameters
Inbetriebnahme suggests the network parameters (subnet mask, gateway, DNS server) that also apply to the PC. If you want the Web-IO to work in the same subnet as the PC, you only need to adjust the IP address. If you select Address range > any network, you can also enter parameters which are different from your local network, for example to pre-configure the Web-IO for a different network. -
Page 27: Basic Settings
Grundeinstellungen 7. Basic settings The further configuration of the Web-IO is done using a web browser. Enter the IP address of the Web IO in the browser command line. In the navigation tree, click Login and choose Administrator as user. By default, no password is assigned and a click on the login button is sufficient to configure the Web-IO with administrator rights. -
Page 28: Date / Time
Grundeinstellungen Pulse mode By activating the Pulse Mode, the output automatically returns to the OFF state after the selected pulse duration when it is switched to the ON state. When switched on again during the pulse, the pulse duration starts counting again. Reset Allowed specifies that the output may also be switched to the OFF state during a current pulse. -
Page 29: Certificates
Basisanwendungen Certificates Protocols such as HTTPS or OPC UA are based on the TLS protocol. The encryption of the communication and the authentication of the communication partners is rea- lized via certificates. The Web IO identifies itself ex works with a self-signed certificate. Many applica- tions consider such certificates to be a security risk. -
Page 30: Basic Applications
Basisanwendungen 8. Basic applications The Web-IO has a wide range of different communication channels and supports various standard protocols. We recommend that you only enable the communication channels that are actually required for your application. This limits the possibility of unauthorized access and manipulation. First of all, we would like to introduce the three most frequently used communication channels: Browser access... - Page 31 Basisanwendungen Home The Home page provides an overview of inputs, outputs and the configured actions. With the appropriate login, the outputs can be switched and the counter can be deleted. Both must first be enabled under Web sites » Home. By default this is disabled.

Integration in bestehende Systeme 9. Integration into existing systems The Web-IO supports some common standards and protocols and can be easily in- tegrated into many installed systems. MQTT After enabling MQTT and configuring in the menu branch Communication paths » MQTT the Web-IO supports two basic possibilities: 1. - Page 35 Integration in bestehende Systeme you determine in which state the output is to be switched or whether the state is to change. Example: A device writes the keyword ON as a topic in the path wut/webio123/set0 of the broker specified in the Web IO. This path and topic are specified as an initiator under MQTT subscribe for the Web IO.

Publish IO states Example of the pulse of a state change at input 1: wut-0a4711/get/input/1 Depending on the state, the payload will be ON or OFF. - Page 37 Integration in bestehende Systeme Read access For read access REST uses the HTTP command GET. The Web IO supports three formats for responses to REST requests: • JSON • • Text The format used for replies can be determined using the request. Using http://<ip-adresse>/rest/json for example opens the entire process image of the Web-IO in JSON format.

A detailed description of the supported REST requests and the structure of the replies can be found in the Web-IO Programming Manual (download at http://WuT.de.). -
Page 41: Opc Ua
Integration in bestehende Systeme OPC UA In addition to the classic OPC access via the W&T OPC server, the Web IO can also be addressed directly via OPC UA. The device provides OPC UA via a binary TCP protocol. The preset port of the server service corresponds to the standard port for this appli- cation: 4840. - Page 42 Integration in bestehende Systeme The device provides you with the OPC UA tree shown in the following (here at the example of the Web-IO #57737).

Aktionen 10. Actions The Action principle allows the Web-IO to issue individual alarms and messages – but also to switch the outputs. This is done based on defined IO states or other events. Up to 12 actions can be created and managed, whereby an individual name can be defined for each action. - Page 48 Aktionen Valid characters: represents all valid values in the respective input field (e.g. every minute or every hour) specifies a range of from…to (e.g. weekday “2-4” stands for Tuesday to Thursday, whereas entering “*” triggers the timer on all weekdays).

- Page 52 Zugriff aus eigenen Anwendungen Switching the own outputs The outputs can be switched to ON or OFF. Another possibility is to toggle the exist- ing state. Alternatively, several outputs can be switched simultaneously. For each selected output, you can specify whether it is to be set to ON or OFF. Switching the outputs of another Web-IO Also in this case, either one specific output or several outputs can be switched.

Page 53: Access From Own Applications
Zugriff aus eigenen Anwendungen 11. Access from own applications In addition to the numerous standardized access possibilities, the Web-IO also offers the option of accessing from your own application. This can be done via TCP/IP sockets from the common high-level languages. However, it is also possible to use common web techniques such as AJAX or PHP to communicate with the web IO. - Page 54 Zugriff aus eigenen Anwendungen The inputs are usually read using a polling procedure. Event-controlled processing is only possible after corresponding configuration of the input triggers.
