Description
PROFINET is a communication protocol designed for data exchange in automation processes between control and peripheral devices, employing Ethernet as its communication medium. It defines cyclic and acyclic communication between the components, offering functional safety, alarms, diagnostics, and additional information. PROFINET can use TCP/IP or UDP/IP data exchange for tasks such as configuration and parameterization, with this method being unusable in time-critical tasks due to the added latency and jitter associated with IP communication. PROFINET utilizes real-time channels for data delivery during time-critical applications, by setting the EtherType field to 0×8892, thus, sending frames from layer 2 to PROFINET layer 7, skipping the TCP/IP stack, avoiding variable time for processing.
