Abnormal code termination. about pylogix

[dmroeder]

Can you post a simple example that causes this issue? It will probably be important to know the tags and their data types.

[TheFern2]

For future reference please provide an mre.

For your case it would be one script with one Read call, in a while loop and a sleep of N seconds. We don't need to know about sms and other stuff going on.

Also ensure that you are using code tags when posting so that is formatted properly.

What are the data types for the tags giving you the exception?

Does the same exception happens when doing individual reads?

When opening an issue there's a template for some questions and you didn't provide those.

OS type and version?
Pylogix version?
Python version?
PLC model?

Good morning. The error manifested itself with the following code. The tags I read are two to simplify. The first is an integer, the other is boolean. I would like to point out that the Raspberry Pi 3 is connected to the PLC via a HyperLAN network at a distance of 10 km. Might you need code that checks the connection and avoids blocking code execution? Let me start by saying that I am a newbie. Thank you.

Ah, okay, the details about the network are important. Seems like maybe the request makes it to the PLC, but you never get a response. I'll have to recreate the same scenario.

[horus61]

Good morning everyone. Is there any news regarding this problem? Thanks for your contribution.

[dmroeder]

Nothing yet. I'll work on it as soon as I can

[dmroeder]

I see what is going on @horus61, I'm working on a fix.

[dmroeder]

@horus61, try 0.9.1
