Hello All,

I would like to choose appropriate computer for redundant Codesys Runtime based on Linux. Redundant - I mean exactly 2 computers with the same codesys.
The system would contain also WebVisu for maximum 3 clients at one time and some postgresql database
I have slow signals(whole system has about 150 analog I/O signals and 300 I/O discrete signals), about 10 distributed I/Os over ethercat fieldbus.
Which CPU: multicore Celeron, Intel Atom, i3.. i5? Some companies say about minimum benchmark points required
How much RAM memory is minimum?
How much HDD memory is required?
Other limitations?

What would You propose for?

Thank You in advance

and best regards,
