Sercos International, provider of the Sercos® automation bus, is presenting various Industry 4.0-capable demos during SPS IPC Drives in Nuremberg from November 22 to 24, in hall 2, stand 440.

Industry 4.0 is being talked about by everyone as a vision of the future. Decentralized intelligence and autarkic behavior, open communication standards and fast connectivity for data exchange in real-time are the requirements for this. In the current motion controls and motion logic systems for hydraulics, Rexroth has moved numerous functions that were previously regulated on a purely hydromechanical basis into software. In the process, the particularities of the fluid technology are automatically compensated for. The decentralized controls execute their tasks autonomously and communicate with superordinate PLCs via open communication interfaces. Thus, users can use the physical advantages of hydraulics in an Industry 4.0 environment. How this works is shown by a new hydraulics demo from Bosch Rexroth, which is making its premiere at the Sercos International stand.

The Sercos SoftMaster Demo scores points with an open “upward” and “downward” communication link. This demo is based on a Sercos III SoftMaster core, which was developed in cooperation with Bosch Rexroth and is being made available as open-source software.

Thanks to the Sercos III SoftMaster, a Sercos III FPGA or ASIC master component is not required. Instead, a standard Ethernet controller is used, with the Sercos III hardware functions emulated in host-based driver software. With this implementation approach, adequate real-time behavior is ensured for a large number of applications. If an Ethernet controller with several queues and telegram scheduling (such as the Intel I210™) is used, even the synchronicity and the highest availabilities of a hardware-based master can be achieved.

Unlike the previous solution with a hardware-based Sercos master, with the Sercos SoftMaster machine, engineers and control manufacturers can now use an industrial PC without special fieldbus hardware and without PCI slots to control the machine. Due to the use of the Sercos SoftMaster in combination with the powerful Intel I210, the CPU load is reduced significantly, while costs and space are also saved.

The Sercos SoftMaster is available as an open-source software license for general use in the software pool of Sercos International e.V. 

“With the provision of a Sercos III SoftMaster implementation as an open source, it becomes much, much easier for manufacturers to develop a Sercos III master and at the same time to participate in future improvements and expansions of the software,” says Peter Lutz, Managing Director of Sercos International. “In this way, control systems can be designed more affordably and will be simpler and more compact in the future. This is a very important criterion.”

In addition to the Sercos SoftMaster demo, additional demos as well as a large number of exhibits forming a cross section of the approximately 250 Sercos-capable products will be displayed in the Sercos stand.
