From: Valerie Demassieux Sent: Thursday, September 28, 2017 9:53 AM To: Glenn Parsons; J.L.Messenger@ieee.org; John Messenger Cc: Tony Capel (capel@comgate.com); Ludwig Winkel - SIEMENS AG (Ludwig.Winkel@Siemens.com); Guenter Hoercher (Guenter.Hoercher@ipa.fraunhofer.de); Rudy Belliardi - Schneider Electric (rudy.belliardi@schneider-electric.com) Subject: Establishment of formal liaisons between IEEE 802.1 and IEC SC65C Dear Mr Parsons, dear Mr Messenger, During our last IEC SC65C Plenary meeting in May 2017, two of our Working Groups expressed their needs to establish liaisons with IEEE 802.1, because work done in your group is of relevance for the current projects of these IEC SC65C groups: • IEC SC65C/MT9: Fieldbus maintenance (convenor: Ludwig Winkel) • IEC SC65C/WG15: High availability networks (convenor: Günter Hörcher) Such an official liaison would be even more needed in the context of a future collaboration on the TSN profile for industrial networks, as this would facilitate the necessary exchange of documents. Could you please indicate whether or not I may proceed with the IEC process for establishment of a D-liaison between IEEE 802.1 and SC65C/MT9 and SC65C/WG15? If you agree, could you please provide advice on any additional process that would have to be followed on your side? The person that would serve as liaison officer from our side would be Mr Rudy Belliardi. Additional or alternate liaison officers may be nominated if needed. If you agree with the liaison process, would it be possible for Mr Rudy Belliardi (or his potential alternate) to attend your meetings without waiting for the end of IEC liaison process (which may require up to 3 months to be completed)? I am looking forward to hearing from you, Best Regards, Valérie Demassieux Secretary, IEC SC65C Rockwell Automation 2, rue René Caudron - Bât A 78960 Voisins-le-Bretonneux - France Tel: +33 (0) 1 61 08 78 72 Fax: +33 (0) 1 61 08 79 49 Email: vdemassieux@ra.rockwell.com
