Just one question for industrial communication which protocol is preferred modbus TCP/IP or Ethernet IP and why?

@framos9991 3 года назад

Perfect! Thanks!

A bit confusing. Ethernet is not a wire. Either is a protocol which can be use over a wire, fiber or wirelessly. You are mixing up your layers. TCP and UDP are layer 4. Application layer has HTTP, FTP, SNMP etc. Is Modbus only UDP? At 8:30 you say Profinet is Ethernet, but then at 8:35 you say it's in the bowls of TCP/IP stack. If Profinet is a Layer 7 Application layer protocol which uses Ethernet what's happening at layers 3 and 4?

+Passed High School Physics 90+% of Profinet traffic is below level 7 of the OSI Model, level 3 and 4 to be precise. This means less processing, faster speed, and in turn higher determinism. image.slidesharecdn.com/profinet-applyingtheethernetstandardtoindustralautomation-peterthomas-140414041007-phpapp01/95/profinet-applying-the-ethernet-standard-to-industral-automation-peter-thomas-10-638.jpg?cb=1397691945There are a few Modbus applications that utilize UDP but the market is dominate by TCP/IP based implementations.For those not as versed in technology the wire is an inaccurate but relatable idea. We agree it is not literally correct.

I didnt get the part at 5:20 you used the valves as an example. why would you use UDP again?

@woutermoors 7 лет назад

Because the control messages are sent a relatively high rate. So it isn't all that important if you miss one. The next message will put the valve in the desired state anyway...

If you were sending voice data it would be useless to resend packets because the words already have been said. It would be better to just drop the tiny bit of the sound and reduce the call quality...
