• The Common Physical Basis
  Symmetrical data transfer/differential voltage signal

• Physical Elements of Ethernet
  Voltage signals/bandwidth/bit rate/bit coding/transmission frequency full duplex/half duplex, Network types: starting from 10Base-2 (coax) through to 100Base-TX/FX, Network structures: line / star / ring, Network addresses: MAC address, IP address, subnet mask, Fundamentals of network design, Cable types: coax / twisted pair / fibre optics, Cable categories: classification, e.g. Cat5e / ClassD, Plug-type connector and wiring diagrams: RJ45 / M12 / BFOC ST / SC, EMC and shield current issues according to EN 50310

• Logical Elements of Ethernet
  Ethernet in ISO/OSI reference model, Ethernet telegram structure, Ethernet protocols: H1 (Siemens), IP, TCP/UDP, FTP, PROFInet, MAC, Active network components: hub, switch, router

• Measuring Devices/Measuring Principles/Measuring Techniques/Diagnosis Theory and Demonstration by Sample Setup
  Diagnosis through standard commands: ping, arp, tracert, The switch as most essential location for network monitoring and troubleshooting, Managing switches: Port statistics, log files, traps, port mirroring, Cable test using „PROlinetest,“, drafting a measuring record acc. to Cat. 5e, Telegram recordings using Wireshark, Manufacturer-independent long-term network monitoring using PROmanage^®, Manufacturer-independent network scanner PROscan^® Active

• Acceptance Conditions/Specifications
  Manufacturer-independent minimum requirements for network planning, installation and testing, Additional requirements for PROFINET networks

• Network Security
  Basic threat scenarios: viruses, worms, unauthorized access

• Network Installation
  The seminar participants build up a network. They can incorporate their own laptops, PC or programming devices (Windows user interface), Installation of cables and plug connectors between PC and switch, Drafting a cable test record acc. to Cat. 5e

• Network Commissioning
  Assigning IP addresses, sub-net marks and gateway, Network commissioning, Control of network function by standard commands, such as ping and arp, Installation errors and how to localize them

• Network Monitoring/Telegram Traffic
  Discussing and simulating actions in the network and verification of the same via the telegram monitor Wireshark, Simulating network loads and errors, Identifying suitable measuring points for telegram recordings

• Switch Management and Verification of Impacts on Network
  Port mirroring, Blocking the telegram traffic, Failure of network connections and reconfiguration via Spanning Tree, Trunking, VLAN, AutoPartitioning, port statistics, Short-term network monitoring/creating fault messages

• Long-term Network Monitoring
  Scanning of network structure using PROscan^® Active, Network monitoring by PROmanage^® using SNMP
