"Job interrupted" error when writing data to the PLC

[FiloCara]

Hello,

First of all, thank you for working on this amazing project.

Describe the bug

I'm currently working on an industrial application which writes multiple data in the PLC. We write simultaneously about 30 variables every 500 ms through a single S7 out node.

I have found that, since version 3.0.0, writing more than 12 variables at the same time, raise a "Job interrupted error". The same behaviour does not appear if we use an older version (i.e. 2.2.1).

The test has been carried out using exactly the same hardware.

Any ideas ?

Thank you

Environment

Hello, we have faced the same issue on a similar project writing multiple data on a CPU 315-2DP. Do you think it's real bug ? if yes is it already plan to integrate this bug in the next fix/release ? thank you.
