correct, 4 bytes for INT32/UINT32/FLOAT. For DOUBLE it should be 8. For you it prints 32

Just post here a minimal script which produces the error, so that I can try myself.

The problem has been fixed on commit 825935dc on Oct. 2021 and runs fine since then at PSI. If TRIUMF people
agree, we can close that issue and proceed.

Midas uses various buffers (in the frontend, at the server side before the SYSTEM buffer, the SYSTEM buffer itself, on the
logger before writing to disk. All these buffers are in RAM and have fast access, so you can fill them pretty quickly. When
they are full, the logger writes to disk, which is slower. So I believe at 2 Hz your disk can keep up with your writing

I have not seen any modbus devices recently, so all my code and examples are quite old.

|
A requested change in the history logging system has been made today. Previously, history values were
logged with a maximum frequency (usually once per second) but also with a minimum frequency, meaning
that values were logged for example every 60 seconds, even if they did not change. This causes a problem.
