Clean & supported/futuresafe PM-way to call Python-Scripts

[captain_feature]

Hy,

as discussed in this thread:

Change ProductVariableName during Process

Hy, but I wasn’t able to find how to get the vcproduct to modify it. I would be happy if I could realise all my stuff with the standards, unfortunatly I can’t for complex machines. I hope the possibilties for customizing everything will never be stoped, because it’s one of the biggest advantages of Visual Components! Thx & Regards Feature

It seems that the “Process”-Statement is not build to exist in future?!

If so, what is the supported and clean way to call custom functionality via phyton-script which is built for future??

I don’t think that I can’t realise my simulation stuff without python-scripting!

Examples:

• Read In machine programs dynamically (xml, json, txt,…)
• Do stuff that is out of box from Process modelling
• Replace missing PM-Feature with Python-logic and functionality
• Do other black magic…

Thx & Regards
Feature

Nobody here can really give you any promises about the future.

The issue with the Python process handler is that its a legacy feature “accidentally” carried over from the robot executor. It is not designed with PM functionality in mind, and neither is PM functionality designed with the process handler in mind.

Extensibility through API is not forgotten, and PM currently (VC 4.2.2) has complete API (.NET and Python) for configuration, with more runtime things probably coming later.

A bit crappy but probably future-proof way to execute Python code in the middle of a PM process is to use the SendSignal and WaitSignal statements. First you trigger a string signal that a Python script reacts to and then wait for a “completion” reply from the script using another signal. With different string values you can run different functions in the script.
