Can PROFINET and Ethernet Employ the Same Switch?

loading… Switches are crucial components in industrial networks. They are commonly implemented in PROFINET configurations to deploy various topology options (i.e., tree, star, line, ring). But are those switches able to handle PROFINET telegrams and other Ethernet traffic? PROFINET can coexist with other Ethernet-based protocols in the same network and share network infrastructure, such as…
