<p>The <a href="Open_source" title="Open source">open source</a> <b>BiSS interface</b> (bidirectional/serial/synchronous) is based on a protocol which implements a real time <a href="Interface_(computing)" title="Interface (computing)">interface</a>. It enables a secure serial digital communication between <a href="Microcontroller" title="Microcontroller">controller</a>, <a href="Sensor" title="Sensor">sensor</a> and <a href="Actuator" title="Actuator">actuator</a>. The BiSS protocol is designed in B mode and C mode (continuously bidirectional mode). It is used in industrial applications which require transfer rates, safety, flexibility and a minimized implementation effort. The BiSS interface has roots in <a href="Synchronous_Serial_Interface" title="Synchronous Serial Interface">SSI</a> and a simplified <a href="INTERBUS" title="INTERBUS">INTERBUS</a>. The proprietary standards, Hiperface and EnDat are competing solutions.

<li>Since BiSS B is not motor feedback compatible, BiSS C has been preferred in the market</li>
<li>All patent cases against BiSS B were dropped in 2012:
<ul><li>EP 0790489B1: "Mode switching by frequency comparison"</li>
<li>DE 19701310B4: "Mode switching as such"</li>
<li>EP 1168120B1: "Block transmission of additional uncritical data"</li></ul></li>
<li>Multi-cycle data (MCD) are no longer utilized in the position sensor system with BiSS</li>
<li>Because BiSS utilizes the <a href="PHY" class="mw-redirect" title="PHY">PHY</a> of <a href="Synchronous_Serial_Interface" title="Synchronous Serial Interface">SSI</a> [(RS-422)], it develops as the successor of the <a href="Synchronous_Serial_Interface" title="Synchronous Serial Interface">SSI</a> interface in automation</li></ul>
