BiSS-C Master CLK BiSS-C BiSS-C Master DAT CLK DAT Master CLK CLK CLK DAT A DAT CLK 1 1 1 0 1 0 1 0 0 1 0 1 0 1 HSSL 0 (digital; bandwith up to 25 MHz and 8-48 bit resolution): attocube's proprietary serial word protocol 0 1 0 provides absolute position information - both in terms of the protocol and the measurement itself. The HSSL 1 0 1 0 interface consists of one data and one clock signal (single ended or differential); position information is packed into one container of user-defineable bit-length, synchronization with the receiver is accomplished using 1 0 1 0 the clock signal. The HSSL protocol is preferential if absolute displacement position data (i.e. sensor-target separation) is required or if incremental position counting is inacceptable. 1 0 1 B A CLK 0 AquadB (digital; bandwith up to 25 MHz; resolution freely assignable): The AquadB interface provides incremental displacement information on target displacement. Position resolution and (maximum) clock rate can be user defined using the IDS web interface. For maximum data bandwidth, the AquadB interface is best used with differential signaling. A A B B A B B Sin/cos (analog; bandwith up to 25 MHz; resolution freely assignable, 1 - 224 pm): The sin/cos signal is a digitally synthesized analog signal which provides incremental position information. As with the digital AquadB signal, the increment (i.e. resolution) is user-definable in the system's web interface. For maximum data bandwidth, the sin/ cos signal is best used with differential signaling. A A B B A B BiSS-C 1 0 BiSS-C BiSS-C The sensor interface offers synchronous, real-time-capable data transmission. It provides point-to-point 0 1 topology 0 for data communication with motion controllers and is especially suitable for the easy integration of several IDS sensors to the master clock at multi device facilities such as synchrotrons and spallation sources. BiSS-C signals are routed through the 14 pin GPIO connector (all other real-time interfaces are disabled in this mode).

For detailed information, please contact EtherCAT (Ethernet for Control Automation Technology) is an open, real-time Ethernet-based fieldbus network originally developed by Beckhoff. The EtherCAT protocol is most typically used for machine control and regulation as well as for multi-channel, synchronous measurement devices. Profinet is a protocol based on industrial Ethernet according to IEEE 802. It connects devices, systems, and cells, facilitating faster, safer, less costly and higher quality manufacturing. A B Profinet RT is the real-time derivative of Profinet. CANopen is a communication protocol based on CAN (Controller Area Network) which is most typically used for the interconnection of complex, embedded systems used in automation. Apart from communication, the CANopen protocol also provides device specification.
