echochange data exchange between Siemens S5/S7

Siemens - Information about the properties of the S7 protocol What properties, advantages and special features does the S7 protocol offer - Siemens Industry Online Support . Discussion Ethernet is just the Physical layer and the Data Link layer. By itself Ethernet does nothing; it’s just the “pipe.” Wholehearted agreement that Ethernet is NOT a protocol. Ethernet is not much different than say RS-485.

ISO/IEC 14908-1:2012 describes services in layers 2 to 7. layered protocol that can be mapped approximately to the OSI 7-layer network model (see Figure 3). On this diagram, Ethernet represents layers 1 (physical) and 2 (data link). The Internet protocol (IP) maps to layer 3 (network).

A Switch Port can be implemented as a separate device, such as the Beckhoff 6601 , which supports all Ethernet (IEEE 802.3)-based protocols, and which is electrically isolated to 500 V. Ripyl protocols¶. The Ripyl library supports a number of protocols for decoding. Protocol decoders can be layered on top of each other. This creates a distinction between base level decoders that operate on raw sample or edge data and higher level decoders that work with the results of a lower level decoder.

On this diagram, Ethernet represents layers 1 (physical) and 2 (data link). The Internet protocol (IP) maps to layer 3 (network). The TCP and UDP transports map to layer 4 (transport).
