6 Industrial Automation Hot Trends Big Data Need for more reliable data collection/storage OPC-UA data security & standardization Industrial Ethernet growth continues OT/IT convergence Need for diagnostic monitoring & quick repairs Following industry standards (TIA 568) IT/Data Center Faster Standards CAT 6, CAT 6A CAT 8 soon.

7 Industrial Ethernet Why is Cable Certification Important? Yesterday Today Emerging Tomorrow Network DH485 DH+ DH-RIO Device Net Data Rate (mbit) Control Net EtherNet/IP (10/100) Ethernet/IP (1000) EtherNet/IP (10G) or 100 1,000 10, ,000 DH485 DH+ DH-RIO DeviceNet Control EtherNet/IP Ethernet/IP EtherNet/IP (10G)? Data Rate (mbps)

8 Why is Complete Cable Testing Important?.. As network bandwidth (data rate) increases.. Carrier frequency increases Impedance (attenuation) increases Signal/noise ratios tighten Crosstalk between pairs increase High frequency signals traveling over copper Poor wiring = poor network performance (DOWN TIME) DC Continuity (zero baud) is not a complete test!

9 Proper Cabling Practices Reduce Risk According to an ISA.org online article, Physical Layer (structured cabling) failures accounted for 35% of total failures in plant automation. Physical deterioration, electrical failure, or poor installation and maintenance practices can all lead to unreliable network performance. loss of critical data system downtime even catastrophic failure

10 Best Practices for Ethernet Testing When installing cabling for industrial Ethernet applications, don t just assume it is going to work. Proper installation, configuration, testing and certification will greatly reduce any start up problems and minimize future downtime.

11 Best Practices for Ethernet Testing What are the cable Gotcha s It is easier to terminate an Ethernet outlet than plug RJ45 outlets are used in patch panels & wall outlets Jack to jack wiring = permanent link Patch cords (with RJ45 plugs) connect equipment to outlet If plugs wear out, replace the cable! If the patch cable is LONG (e.g. run through conduit), repair time is LONGER

12 Best Practices for Ethernet Testing What are the cable Gotcha s Connector termination issues Obvious miswiring/shorts/opens Shield not connected Precision terminations to limit de-pairing Cross talk/noise too high

13 Best Practices for Ethernet Testing What are the cable Gotcha s Cable installation issues Too close to other cables or electrical equipment (noise) Cable (pairing) damaged Bend radius exceeded Cable crush/kinked Tie wraps used!!!! Cable is too long Cable is defective (counterfeit?)

14 What Certification is All About Ensuring that the cable infrastructure MEETS the standards The network DEPENDS on Layer One! Reducing start-up time Reducing finger pointing when network problems arise 80+% of industrial network problems are cabling oriented! A REQUIREMENT for the manufacturers warranty (Belden, etc) Certification is PART of the TIA 568 standard! Certification is the NORM for commercial installations why not industrial? Certifiers also make excellent troubleshooting tools reduce downtime

15 What is required to Certify a cable? 190,000 different measurements needed to Certify! Measurement Dynamic Wiremap Loop Resistance Cable Length Near End Crosstalk (NEXT) PowerSum NEXT Insertion Loss (Attenuation) ACR-N PowerSum ACR-N Return Loss (RL) ACR-F (ELFEXT) PowerSum ACR-F Propagation Delay Delay Skew Description Accurately detects Open/Short and Distance to Fault from both ends of the cable The resistance between the two conductors of a twisted pair which is looped back at the far end The length of the cable under test The interference at the near end of a pair caused by signal on another pair The sum of the individual NEXT effects on each pair by the other three pairs The decrease in signal strength from one end of the cable to the other The difference between insertion loss and near-end crosstalk (NEXT) The sum of the individual ACR-N effects on each pair by the other three pairs Signal loss caused by structural imperfections in the cable The interference at the far end of a pair caused by signal on another pair, with the insertion loss subtracted The sum of the individual ACR-F effects on each pair by the other three pairs Time it takes for a signal to travel from one end of a cable to the other The difference in time between the fastest and slowest pairs within a cable Each cable test collects 190,000 data measurements!!!!

16 What is required to Certify a cable?

17 Fastest, Most Accurate, User Friendly and Future Proof Cable Certifier on market!

18 WireXpert Advanced Cable Certifier Certifies and tests: CAT 5e, 6 and 6A (CAT 8) Copper Standards Multi-mode and Single Mode Fiber RJ45 & M12 connectors Documents and reports cable/connector manufacture models Produces Certification Reports

19 What Does Certification Measure? What tests are performed? 9 seconds Autotest Pass or Fail on display Wiremap & crosstalk data on display Location to fault Data downloadable to PC Formal reports

20 export - Professional cable test management software Quickly organize, edit, view, print, save, or archive test results by jobsite, customer, campus building, and more Deliver professional, customized (your company s logo), graphical test results Export in summary or graphical layout, all or any number of tests, to either.csv or.pdf format

21 Example Cable Certification Report

22 Ethernet Cable Qualification Qualification is NOT Certification, but Cable Qualifiers: Use many of the same measurement methods as certifiers Identify cable issues and location of faults May perform additional online tests DO NOT produce certification reports But may offer other useful reports Qualifiers cost less than Certifiers may fit the budget! PROFIBUS Diagnostics

23 Cable Testing, Speed Testing, Network Testing
