The Strange Physical World of Industrial Ethernet Mike Nager, METZ CONNECT USA Inc. 1 12/25/2022

What is Industrial Ethernet? It’s a specific type of “Internet of Things” used to describe Ethernet used on manufacturing plant floors or in process facilities. It is rapidly growing already. 23% of the 31.3 million industrial networked nodes in 2011 were based on Ethernet. – IMS Research Total economic value of IoT will be 1.9T by 2020 with manufacturing and health care verticals leading at 15% each. – Gartner Inc. 2 12/25/2022

“Industrial” Looks Different Ethernet is the biggest thing to hit manufacturing facilities but it’s a lot different then the typical Enterprise network. According to IMS Research only about 40% of installed industrial Ethernet nodes are standard TCP/IP and seems to be decreasing slightly over time. 6 12/25/2022

A Look at the Past Islands of Automation Machines were self contained entities with little communication between each other or the plant facility. Relay logic prevailed. 7 12/25/2022

A Look at the Past Islands of Automation Relays were replaced by PLCs and remained ‘standalone’. Some specialized networks started to replace the direct wiring but control and information remained locked to that machine.[email protected]/267323861/in/ photolist-pC756-3RpqjT-4b86wT-4bc7HW-4bc7NQ-73JDy1eoYJAp-fySBbZ-aTkNbV-aTkLQ2-aTkP8P-a3Qx5T-bjcrXKaTkxyg-aTkeA6-faqaCM-faqaVz-cLL5F3-awSD6D-dzbGD5b1XcEn-8dkSKQ-bie2Q4-bidUjp-a17jSR-a17iPX-a1abCoa17jki-a1aaRf-a17jbZ-a1ab2J-a17j8x-a1aaLd-a17jxn-a1abeja17jAp-9ZNoSk-9ZRf8W-a1ab3J-a1aaFW-ffTdSt-a1ab4Ya17j2X-a17jRi-a17jrF-a17jEK-a17jqB-a17jHD-a17jmn-a17jS4a1abib 8 12/25/2022

Ethernet to the Rescue Islands of Automation Ethernet was seen as method of extracting information from the PLC and maybe even its I/O so at least reports could be made. ETHERNET 12/25/2022 DeviceNet GW 9 GW GW GW Discrete Control Profibus SERCOS

Progression But Why Not All the Way? If machines were connected via Ethernet, why couldn't they be CONTROLLED by Ethernet? Little by little, the objections were overcome. 10 Ethernet isn’t Fast Enough – We need ‘Real Time Controls’ Ethernet isn’t Deterministic – We can’t have jitter Ethernet Topography isn’t suitable – Star won’t work Ethernet isn’t redundant – Can’t have single Source of failure Ethernet Components aren’t designed for industry – this presentation! 12/25/2022

Cable Recommendations Profinet recommends Shielded Cables Ethernet/IP prefers unshielded systems - But Recommends shielding for Induction welding processes RF Sources Electrostatic processes High current devices (more than 100 amps) - Uses shields with RC network to prevent DC ground loops 21 12/25/2022

Physical Layer Issues According to an online article, Physical Layer failures accounted for 35% of total failures in plant automation Two ways to provide reliability is to – Harden the physical layer – Change the network topography 22 12/25/2022

Connector Recommendation Industrial Control Manufacturers Guidelines are given by the manufacturers, in this case for EtherNet/IP systems. 23 12/25/2022

Reliable Extensions and Repairs Practicality Repairs and Extensions to Ethernet cable need to be done on the plant floor – they will not re-run wires through plants or machines with moving parts unless absolutely necessary. Think of it as a type of consolidation point. 35 12/25/2022

Key Take-Aways Internet of Things is growing rapidly Much of it is in the industrial sector – Industrial Ethernet Environmental considerations are much different than office environments Physical component failure is the single biggest failure point so the physical layer components have to be well considered 36 12/25/2022
