Is PROFIBUS Based on Ethernet?
Read: Is PROFIBUS Based on Ethernet?Industrial communication protocols, such as PROFIBUS and PROFINET, are based on different physical layers. PROFIBUS is based on RS-485, which is a common serial communication method. PROFIBUS networks can achieve speeds of up to 12 Mbit/s, though most networks run at 1.5 Mbit/s. The telegram size can be up to 244 bytes, and the address…
