I hate MontiArc; what can I do?

Well, MBSE is not for everyone. Maybe take a C lesson next?

I got the error 0xC1117 and don't know how to fix it

The error tells you that you have a non-delayed feedback loop. This means the inputs of a component directly or indirectly depend on its own outputs. To fix this, add a delay somewhere in the loop.

When should I use event ports vs sync ports?

Depending on what you want to model you can choose different timings.
Here is a quick overview of when to choose a timing:

Timed

• Perfect for asynchronous communication
• Discrete events that occur never, once, or multiple times inside a time frame
• Ask yourself: Do I model Software?

Synchronous

• Discrete messages that are sent once per time frame
• All messages are sent and received at the same time
• Ask yourself: Do I model Hardware or Software that is continuously updated?

I want to read from two event ports at the same time

Think about why you want to do that, maybe event ports are not the right approach to your problem. To solve this, you can:

• Make the ports synchronous
• Use a component field to buffer the events.
