WinCC V8.0 Step By Step 28: Create A REST Connection to Weather Service 🌩️🌞☔
This is #28 in our Siemens SIMATIC WinCC V8 Course. Here we show you how to use the WinCC V8 REST Connector feature to connect to a Weather Service REST API to bring in local weather information into your SCADA Application. We will create and test our connection, and build a screen in Graphics Designer to trigger the connection and show the JSON Response from the REST API. Then we will write some VB Script to parse the data into internal tags. Be sure to watch 'til the end!
