Is it possible to have 2 devices with same IP communicate on 1 3 layer switch ?

Imagine 2 PLC with same IP cross paths at the same time on a 3 layer switch. Is this possible without one getting knocked off the network ? I only have 1 switch to make this work somehow. This happening is highly unlikely, but it’s possible. Is it possible to send these through VLANs ? I connected 2 PLC in my lab that had the same IP but of course one got knocked off.
