BiSS C Protocol Description Revised

BiSS Association, Technical Updates
Published 11.08.2023

Within the last 20 years, BiSS has become a popular interface for fast, isochronous sensor data transmission. More than 600 licensees spread all over the world have already implemented BiSS C – and its user community is still growing.

We believe that the exceptional popularity of BiSS is a great reason to release a fundamental revision of the BiSS C Protocol Description with lots of improvements, new pictures and practical hints. Check the latest update of the

Functional Safety Seminar – an Introduction based on Requirement for Automation Drives

Presentations/ Seminars
Published 06.02.2019

Functional safety is increasingly requested for drives. Safe Torque Off (STO) is now standard on many frequency inverters and servo drives. Safe motion and safety related field buses are an increasing demand. The technical basics of functional safety are explained in this seminar. This seminar is intended for designers and engineers involved in frequency inverter and servo drive design for automation. It assumes a working knowledge of electrical engineering basics and a familiarity with inverter design principles.

Lecture: implementation of a robust communication in motor feedback systems

Presentations/ Seminars
Published 24.01.2019

The BiSS Association e.V. will present the lecture at the Praxisforum Elektrische Antriebstechnik in Würzburg, Germany.

Implementation of a robust communication in the motor feedback system with control, sensors, motor as a source of interference, cabling, less plug connectors.

It considers the industrial communication with the focus on the electric drive technology. The requirements of this communication and the current and current implementations as well as details, problems and possible solutions are considered. Here, the physics and mathematics of data transmission is used to compensate in particular the disturbances and inadequacies of the real world. Like any commercial solution, the costs and benefits must be taken into account. In addition, the topics standardization and feasibility are relevant.

The aim is to be able to evaluate the robustness of a communication with the framework conditions and solutions.

Speaker: Marko Hepp | BiSS Association e.V.

Praxisforum Antriebstechnik 2019

The lecture will be held in german language.

User Group founds BiSS Association as a Platform for the Open Source BiSS Interface

BiSS Association
Published 28.09.2017

The open source BiSS interface has turned over a new leaf. The bidirectional sensor interface introduced by iC-Haus in 2002 has now been licensed over 450 times free of charge and has established itself as a worldwide standard in encoder and drive technology. BiSS is bus-compatible and is characterized by the continuous communication of sensor and parameter data, especially in efficient and fast motor control systems. The BiSS Safety protocol is TÜV-certified. Continue reading →

Beckhoff presents 2-channel BiSS-C interface EL5042

BiSS Products
Published 30.05.2017

The 2-channel BiSS C interface for direct connection of BiSS C encoders is suitable for exact and fast positioning applications – with distributed clocks ensuring high synchronicity with other processes. Via unidirectional BiSS C communication, the EL5042 sends as a master the clock signal for position detection to the BiSS C slave (encoder), which returns the position data with up to 64-bit resolution. The EL5042 can be optimally adapted to different encoder types by selecting appropriate operation modes, transmission frequencies and frame widths.

The EtherCAT Terminal system is a modular I/O system consisting of electronic terminal blocks. The EtherCAT protocol remains fully intact down to the individual terminal. Beckhoff provides an extensive range of fieldbus components for all common I/O and fieldbus systems. The wide choice of I/O components means that the bus system best suited to the particular application can be chosen.
