2. Foundation Fieldbus H1 - Wikipedia

   en.wikipedia.org/wiki/Foundation_Fieldbus_H1

   The hub-and-spoke tree topology of Ethernet makes it very easy to add and remove devices without upsetting the operating network. Because Foundation HSE is based on unmodified Ethernet, standard Ethernet tools can be used for installation qualification, testing, and troubleshooting. These tools speed up the resolution of communication problems.

3. AS-Interface - Wikipedia

   en.wikipedia.org/wiki/AS-interface

   ASi-5 is to provide a set of up to 1536 binary inputs and 1536 binary outputs per Ethernet address. 1.2 ms cycle time can be achieved by the system for up to 24 participants. This fast cycle time allows new fields of applications that were previously reserved for expensive network systems. 96 participants can be addressed in an ASi-5 network.

   Ethernet cable with an M12 X-coded connector in one end and a modular connector in the other. IEC metric screw sized connectors is a family of electrical connectors defined by IEC that are named according to their ISO metric screw thread , namely M5 , M8 and M12 . [ 1 ]

6. 5-4-3 rule - Wikipedia

   en.wikipedia.org/wiki/5-4-3_rule

   The 5-4-3 rule, also referred to as the IEEE way, is a design guideline for Ethernet computer networks covering the number of repeaters and segments on shared-medium Ethernet backbones in a tree topology. [1] [2] It means that in a collision domain there should be at most 5 segments tied together with 4 repeaters, with up to 3 mixing segments ...

7. EtherType - Wikipedia

   en.wikipedia.org/wiki/EtherType

   With the advent of the IEEE 802 suite of standards, a Subnetwork Access Protocol (SNAP) header combined with an IEEE 802.2 LLC header is used to transmit the EtherType of a payload for IEEE 802 networks other than Ethernet, as well as for non-IEEE networks that use the IEEE 802.2 LLC header, such as FDDI. However, for Ethernet, Ethernet II ...
