WELCOME

This post is inspired by a recent question in the Siemens community forum ( https://community.sw.siemens.com/s/question/0D5Vb00000rlev1KAA/help-with-counter-triggered-by-operation-end-signal-in-process-simulate ). It seems generic enough to be mentioned here. It is actually pretty simple but can be really useful in many situations. So how do you count how many times an operation has been executed? You just increment a counter on each pulse of the operation's end signal. A

This should be a device that detects a substance within a specified volume of space. Usually used in security systems this kind of sensor is also known as a volumetric motion detector. It detects changes in the volume it covers by filling it with energy patterns and recognizing disturbances in the patterns caused by any moving object. In our case it works by simply looking for interference between the geometry of volume itself and the geometry of any part appearance. As you

What are literals? These are the constant values that we use in the code. Examples are: numbers ( 1 , 2 , 10#1 , 16#FF , 8#77 , 3.14 ,...

Introspection means extracting semantic (meaningful) information from the code. For example: getting variable names, type names, default...

Scripting is nice. I think we all agree with this statement. It would be even nicer if we can automate the process of creating scripts. e.g. generate and assign scripts to resources over the official API of Process Simulate. Is this really possible? Yes it is. The SCL editor does exactly this. It uses the API to assign a script to a resource. It can also set default values for variables as well as connect signals to them. Let's see how this works. Every resource that can h

As the name suggests this is a device that measures frequency. It counts the number of pulses in a periodic signal per second. Internally...
