Hi all,
I have to make a little project including some DI, DO and AI.
The PLC must be a S7-300 serie and have to include a panel also
I need about 30 DI +/-4, 12 +/-4 DO and 7AI (11-12bit).
The project is for controlling waterflow, based on UV-intencity.
It is not a fast application (scantime >100ms is ok).
I would like to go online without disconnecting the panel (2 ports? or DP?)
have 230VAC or 24VDC for supply and 24VDC for transmitteres etc.
I was thinking of CPU 313C-2 (ptp or DP) do not know what is best, + 32DI + 16DO + 8AI
or else
CPU 314C-2 (ptp or dp) + 16DI + 16DO + 8AI
I do not know what panel to use either.
Can someone help me in the right direction?!
Thank you
Dariusch
