Many different bus systems have established themselves in the field of industrial communication. In order to provide our customers with maximum flexibility we implement solutions that meet the requirements of all the most popular systems.

Baumüller drive technology supports the six most popular field bus systems EtherCAT®, Sercos®, Ethernet, CANopen, CANsync and Profibus®.

Ethernet

EtherCAT®
The latest Ethernet technology from Baumüller is a prerequisite for highly synchronous and precise manufacturing processes with maximum quality. For the first time, Baumüller is providing an economical combination of drive bus, field bus and different interfaces in the automation architecture.

EtherCAT is an Ethernet-based, real-time, synchronous field bus system with excellent performance capability. Software profiles based upon existing standards are implemented, based upon the EtherCAT connection.

It couldn’t be easier for users to switch to Baumüller‘s new field bus technology: From the user’s point of view the drive and automation profile structures are almost identical, and the application programs are unchanged.

SERCOS®
b maXX with the SERCOS option card is already being used in many applications, particularly if there is a requirement for proper real-time processing. The phase run-up that is defined in the SERCOS interface specification is fully supported by the option card.

The software operates using preferential telegrams 3 and 4. If the higher-order controller only supports telegram 7, preferential telegrams 3 and 4 are emulated in the slave.

CANopen / CANsync
CANopen uses so-called soft synchronization using high-priority messages. CANsync, on the other hand, uses hard synchronization. This is carried out using an additional pulse line for the synchronizing signal. Jitter of ± 1 µs is achieved in the synchronizing cycle using this method.

CANsync ensures that all setpoints are taken over and processed at the same time, irrespective of the number of subscribers. The drive reactions are therefore synchronized over the entire network. The actual value messages from the slaves can be exactly assigned to the time of origin in the same way. This synchronization makes it possible to increase the accuracy and dynamics of the machine significantly in comparison to conventional technology.

PROFIBUS DP®
The PROFIBUS DP option card connects b maXX to a PROFIBUS network as a slave. Up to eight cyclic setpoints and actual values can be transmitted. Free access is provided to any drive parameters for operating and monitoring purposes.
