Stefan, first of all: fantastic work! This little module got me right out of the blocks.

I stumbled upon an issue I am unable to resolve:

read_by_name, write_by_name both work just fine. Any ideas what read_list_by_name is complaining about?

My host machine is Ubuntu 20.04, my PLC is a TwinCAT3 machine.

Thank you for your support! Best regards, Adrian

PS: I am obviously too dumb to get code snippets to format properly... (facepalm) I apologize for the picture.

I think this is the same issue as #232 . Therefore can i polielty ask you to close this issue and we can track it through #232.
