Sercos SoftMaster Training in China

04/11/2018 to 04/13/2018

09:00 - 17:00 hrs
Training room 1, Building 1 #231, Jiaochangkou Street 1
Deshengmenwai, Xicheng District, Beijing, 100120, China

Invitation for Training on Sercos SoftMaster -- the open source, free, and high performance solution

Sercos® has been a world-leading communication protocol among controllers, drives and decentralized peripherals since the 80’s of last century. The unique features that distinguish Sercos from other protocols include:

  • a common infrastructure for multiple types of Ethernet protocols (e.g., TCP/IP, Ethernet/IP, CIP Safety, OPC UA, etc.)
  • complete direct bi-directional cross-communication between any 2 slaves within 1 cycle regardless of the sequence of the devices
  • a common technology independent from specific manufacturers.

Of course, other performance data are also of the most excellent ones, for instance, high speed (cycle time down to 31.25μs), high precision (less than 100 ns synchronization), double ring redundant data transmission, SIL3 Safety, automatic recognition of topology, hot-plug, plug & play, etc.. 

With the SoftMaster on standard Ethernet card, we can achieve cycle times of just under 500 µs. TTS (Time Triggered Send) capable hardware such as, Intel I210 or TI Sitara PRU ICSS, cycle times of 125 µs can be achieved and the synchronization precision is the same as with Sercos hard masters, which is between 60 and 100 ns, depending on the PHY adopted. From this aspect, we are still somewhat limited by cycle time, but we have eliminated all the disadvantages, and can enjoy the advantages in terms of cost and use of cost-efficient standard hardware dominate.

Wide successful applications in such demanding fields as machine tools, packaging machines, printing machines, robots, wood-working machines, and plastic injection molding machines, for nearly 30 years, make Sercos a defacto standard for demanding applications which has extreme high requirements on both the dynamics and the precision. In recent years, Sercos has also been successfully applied in some new fields, e.g., electronic circuits on thin plastic films, machine vision, coating robots which requires explosion-proof safety. It means that Sercos has already become an open universal real-time bus that can be applied in various applications in automation fields, which gained world-wide approval.

On vast requests from the market, a deep training on Sercos SoftMaster will be held in China. Dr. Gunther May, R&D director of Bosch Rexroth and developer of the Sercos SoftMaster, will come to China to guide the engineers to implement SoftMaster on their own IPC. Mr. Peter Lutz, Managing Director of Sercos International, will guide the engineers with the necessary theories.
