Yes, the switches do something along the lines of store and forward.

the sender datalogger?
Again, if your traffic is low, you won't have buffer overrun. If
packets are dropped for whatever reason, the sending datalogger won't
receive it's TCP/IP ack, and will resend.
_ The datalogger must support full duplex or the switch could reproduce
a colission signal if needed?
It's not a collision signal, it's a lack-of-ack that causes the retry.
