[BUG] Save on value change does not work using S7 and reading EB blocks

[wonka929]

Describe the bug
I had different values to read from a Siemens PLC.
Some are DB blocks, some are EB blocks (like E188.3, E188.6, E188.7, E188.1 and so on).
I set the polling interval to 5 seconds and activated the flag "save on changevalue" for saving the value just on change on DAQ.
DB tags acted as expected, but EB tags have been saved at every polling occurrence, so every 5 seconds even if the values was the same.
Strange behaviour.

Expected behavior
EB tags should be saved at changevalue when the flag is set.

Environment

• FUXA version: 1.1.19
• Platform/OS: docker from dockerhub, host ubuntu 24.04

Hi, i have just tested with version 1.2.3 and cannot reproduce the problem. if you enable DAQ you also set a fixed interval for which the value is recorded anyway, regardless of it changing.
