Sometimes one needs to quickly test web page or web app by changing the geolocation coordinates and look at the result.

Type about::config in the URL bar, then type geo.wifi.uri under search.

Set the parameter value as follows: data: application/json,{"location": {"lat": 64.1483407, "lng": -21.9403197}, "accuracy": 1200.0}, and now you are in downtown Reykjavik, Iceland.

Maniputate the latitude (decimal degrees [-90 .. 90], North is positive and South is negative), longitude (decimal degrees [-180 .. 180], East is positive and West is negative) and accuracy (in meters) to quickly simulate the desired position.

When testing is finished, do not forget to reset the parameter to default value!

Simatic MC7 code

In this project it was researched how Simatic STL instructions are translated into MC7 code and based on that possible optimisations are proposed.

Essentially MC7 code in Simatic S7 ecosystem plays the same role as bytecode in Java.
