According to the manufacturer, the Antaios multi-fieldbus communication chip from Profichip enables the flexible implementation of high-performance real-time Ethernet communication protocols such as Profinet IRT or TSN/OPC UA. The chip's real-time Ethernet unit is programmable, which means that all Ethernet-based protocols can be supported. In contrast to other implementations, the I/O data is made available via a hardware interface (consistency interface). Slow access via software callback functions and longer copy routines are not necessary. This means that the I/O data is available in real time. The user also has the option of separating the Profinet consumer/provider states from the I/O data via the consistency interface. The multi-fieldbus communication chip supports all Ethernet-based protocols: it can be used as an Ethercat slave controller. Services such as EoE (Ethernet over Ethercat), FoE (File Access over Ethercat) and CoE (CANopen over Ethercat) are supported. A certified Profinet I/O device software stack with various application examples is also available. A software library (client and server) is available for Modbus/TCP. Master and slave software stacks are also available for Mechatrolink-III. Certification of the chip for Ethernet/IP is planned for the first quarter of 2019. In the area of TSN with OPC UA, initial adaptations have already been implemented in the Antaios microcode.
