Course components



  • topologies in communication networks: point-to-point, line, ring, star
  • notations in communication standards: service description, sequence diagram, state chart (Mealy-type)
  • ISO/OSI reference model: layer, encapsulation, functionality, service types (peer-to-peer, local), PDU-SDU-PCI-ICI, connection-oriented and connectionless communication
  • bit coding: digital (NRZ, PRZ, BiPhase-L, DPLM,...), analog (ASK, FSK, PSK, ...)
  • physical layer definitions of RS-232, RS-485
  • error detection: parity, block codes, checksum, CRC, ...
  • media access schemes: master/slave, token, CSMA/CD, CSMA/CA, ...
  • PhL and DLL of CAN (controller area network): content-based adressing, arbitration, error detection, standard vs. extended CAN, bit timing, fault management, acknowledge mechanism, services and protocols

Acquired Skills
  • students acquire fundamental knowledge on industrial communication systems
  • they understand how communication standards are specified and can apply them to given tasks
  • they understand fundamental concepts in the physical layer and can apply coding standards to create and analyze corresponding signal traces
