Time sensitive networking (TSN) has been gaining a great deal of attention over the past few years via fast moves to develop the standard, technology supplier commitments to the technology and the emergence of a testbed hosted by the Industrial Internet Consortium to prove out the concept. As TSN-enabled products start to hit the market, and with more on the way, technology suppliers are starting to clarify their position on TSN and how they plan to leverage the technology in the near term.<\/p>\n

\"\"<\/p>\n

At the Siemens Automation Summit 2018 last week, Rainer Brehm, vice president for Siemens automation products and systems, explained how Siemens is aligning its use of TSN around Profinet and OPC UA. He highlighted three key industrial network communication aspects of Siemens strategy around TSN:<\/p>\n

<\/section>\n
    \n
  • OPC UA will be used for vertical communication of acyclic data and for controller-controller communications;<\/li>\n
  • Profinet will be used for cyclic and real-time capable I\/O data exchange at the field level; and<\/li>\n
  • Because OPC UA and Profinet can share the same network, they will be used together to enable field level device data to be sent to SCADA, MES and ERP systems, as well as to the cloud.<\/li>\n<\/ul>\n

    \u201cOn standard Ethernet alone, you can’t run two real-time networks at once, but you can with TSN,\u201d said Brehm. \u201cOPC UA with TSN is more powerful because we can get guaranteed quality of real-time service using standard chips.\u201d<\/p>\n

    More specifically, Brehm noted that Siemens\u2019 use of Profinet based on TSN will be focused on fieldbus, while their focus on OPC UA on TSN will be concentrated on machine integration.<\/p>\n

    Brehm said the incorporation of TSN on Profinet will help future-proof the protocol thanks to IEEE\u2019s 802.1 standardization of TSN. Profinet will also get increased bandwidth with TSN\u2014up to 1 gigabit, have the ability provide real time capability with standard chips, and be able to extend existing applications by maintaining the Profinet application layer.<\/p>\n

    With OPC UA, Siemens can more easily deliver machine networking via the open, global standards of OPC UA and TSN said Brehm. We can also provide real-time machine-to-machine (M2M) communication via OPC UA using client\/server, pub\/sub or pub\/sub TSN.<\/p>\n

    Brehm highlighted a recent Siemens TSN demonstration from this year\u2019s Hannover Messe that illustrated robust and reliable Ethernet communication between machines using TSN under high network load conditions. For this demonstration, which showcased synchronized motion capabilities, Siemens used OPC UA pub\/sub together with TSN for M2M communication to connect two robots, each of which communicated over Profinet with a Simatic controller.<\/p>\n

    Siemens used this demonstration to highlight an important underlying element of the pub\/sub principle. Using this method, a publisher, such as a machine control, sends data to the network which is then available to all subscribers. The subscribers then determine, based on their programming, whether they require this information. Reservation of bandwidth in this way, i.e., not sending every bit of data to every connected device, ensures data transmission within the TSN network in a predictable form regardless of the network load.<\/p>\n

    Use of the Profinet protocol with OPC UA TSN is also a key aspect of Siemens strategy for implementing the Profisafe safety protocol over OPC UA. \u201cProfisafe over OPC UA will become an open and highly competitive solution for functional safety,\u201d Brehm said.<\/p>\n

    Though Siemens\u2019 first TSN-based products will be available soon, Brehm said it will likely \u201ctake several years until (the IEEE TSN) standard is finalized and a (TSN) eco-system is established.\u201d<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
