But how will it work out? Every change of state will trigger the sequence? Or it will be done automatically? |

Hi, this depends on which s7 input node you use. I would recommend using the input node from "node-red-contrib-s7". There you can decide whether you want to trigger the flow cyclically so for example every 100ms or only when the value of the variable changes. Then you also need a function node between the s7-input node and the http-request node which only emits a value (triggers the http-request node) if the digital input is pressed or rather the variable is true. |
