While tight coordination is desirable for discrete inputs and outputs, it is especially important in <a href="/wiki/Motion_control" title="Motion control">motion controls</a>, where directing the movement of individual axes of motion must be precisely coordinated so that the motion of the entire system follows a desired path. Types of equipment requiring such coordination include metal cutting <a href="/wiki/Machine_tools" class="mw-redirect" title="Machine tools">machine tools</a>, metal forming equipment, assembly machinery, packaging machinery, robotics, printing machinery and material handling equipment. The <b>Sercos</b> (<b>se</b>rial <b>r</b>eal-time <b>co</b>mmunication <b>s</b>ystem) interface is a globally standardized open digital interface for the communication between industrial controls, motion devices (drives) and input output devices (I/O). Sercos I and II are standardized in IEC 61491 and EN 61491. Sercos III is specified in standards IEC 61800-7; IEC 61784-1, -2, -3 and IEC 61158. Sercos is designed to provide <a href="/wiki/Hard_real-time" class="mw-redirect" title="Hard real-time">hard real-time</a>, high performance communications between industrial <a href="/wiki/Motion_control" title="Motion control">motion controls</a> and digital <a href="/wiki/Servo_drive" title="Servo drive">servo drives</a>. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="History">History</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=SERCOS_interface&action=edit&section=1" title="Edit section: History"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Until the early 1980s the majority of servo drive systems used to control motion in industrial machinery were based upon <a href="/wiki/Analog_electronics" class="mw-redirect" title="Analog electronics">analog electronics</a>. The accepted interface to control such devices was an analog voltage signal, where polarity represented the desired direction of motion, and magnitude represented the desired speed or torque. In the 1980s, drive systems and devices based on digital technology began to emerge. A new method needed to be devised to communicate with, and control such units, as their capabilities could not be exploited with the traditional interface method used with analog drives. The earliest interfaces were either proprietary to one vendor or designed only for a single purpose, making it difficult for users of motion control systems to freely interchange motion control and drives. The membership of the VDW (German Machine Tool Builders' Association) became concerned with the implications of this trend. In response to that, in 1987 the VDW formed a joint working group with the ZVEI (German Electrical and Electronics Industry Association) to develop an open interface specification appropriate for digital-drive systems.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> The resulting specification, entitled "Sercos (<b>se</b>rial <b>r</b>eal-time <b>co</b>mmunication <b>s</b>ystem) interface, was released and later submitted to the <a href="/wiki/International_Electrotechnical_Commission" title="International Electrotechnical Commission">IEC</a>, which in 1995 released it as IEC 61491.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> After the release of the original standard, original working group member companies including <a href="/wiki/ABB_Group" class="mw-redirect" title="ABB Group">ABB</a>, <a href="/wiki/AEG_(German_company)" title="AEG (German company)">AEG</a>, AMK, <a href="/wiki/Robert_Bosch" title="Robert Bosch">Robert Bosch</a>, <a href="/wiki/Indramat" title="Indramat">Indramat</a>, and <a href="/wiki/Siemens" title="Siemens">Siemens</a> founded the "Interest Group Sercos" to steward the standard.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> Over the history of Sercos, its capabilities have been enhanced to the point where today it is not only used for motion control systems, but as a universal automation bus. </p> <div class="mw-heading mw-heading2"><h2 id="Versions">Versions</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=SERCOS_interface&action=edit&section=2" title="Edit section: Versions"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p><b>Sercos I</b> was released in 1991.
