Members have the right to use the SERCOS interface® trademark in literature, in their promotion, and on SERCOS interface products that have passed a conformance test. Non-members must pay ¼ of the regular yearly membership fee for this right. Note that the trademarked SERCOS interface name does not appear in the IEC 61491 standard, so a product developed to that standard does not necessarily have the right to be designated a SERCOS interface product. Members enjoy a significant discount on the license that provides the right to load the SERCOS III Core onto an FPGA to create a SERCOS III master or slave controller. Member dues help maintain the environment for continued development of the SERCOS interface standard. The SERCOS trade organizations invest considerable resources insuring that the SERCOS interface standard continues as the premier standard for high speed digital motion control. This includes regular updates and major initiatives, such as development of SERCOS III using Industrial Ethernet, development of the Packaging Profile, CIP Safety on SERCOS, Controller-to-Controller Profile and new SERCOS III I/O Profile. A product must pass a conformance test before the SERCOS interface logo can be used on that product. Members receive a 30% (approximate) price reduction (compared to non-member price) on conformance testing of SERCOS interface devices. In addition, SERCOS Association members receive no-charge issuance of certification of SERCOS interface products after they pass the conformance tests. Non-members are charged 500 EURO per device for issuance of a certificate. Conformance test tools are available to members at a reduced price. Members are eligible to participate in Plug Fests in which SERCOS III master and slave devices from various members are tested crosswise to insure that the devices are interoperable. These events are held at the SERCOS Conformance Testing Center at ISW at the University of Stuttgart. The SERCOS Technical Working Groups (TWG) meet several times a year in the U.S. and Europe to resolve any problems or issues with SERCOS functions, to develop various profiles such as the Packaging Profile, CIP Safety on SERCOS, Controller-to-Controller Profile and the new SERCOS III I/O Profile and to define and add new standard functions, as suggested by members. Participation in these groups is a benefit of membership. Members receive access to preliminary SERCOS interface technical updates produced by the Technical Working Groups. Non-members cannot obtain this information until it is released and published for sale. Published, released updates to the specification, technical manuals and other documents are available for purchase by non-members; they are free to members. Members participate in meetings (North America, Europe, Japan) for exchange of technical data and association business issues. Members receive no-charge listings on the SERCOS website, in various promotions, product guides and in trade shows. Member products are promoted on the SERCOS website. Members have access to association information databases. Members participate in the SERCOS interface booth at trade shows and exhibitions (Hannover Fair, for instance) at cost. Non-members pay 50% additional. Members receive up to 50% attendance fee reduction at SERCOS-sponsored presentations and seminars.
