PROFINET and Industrial Ethernet

The network under most Siemens plants: industrial networks and the automation pyramid, what PROFINET is, RT and IRT, GSD files, device names, addressing, installation and network design, PROFIsafe and OPC UA on PROFINET, AS-i and other devices through gateways, and advanced protocol training.

  • Place networks in the automation pyramid and the OSI model
  • Explain PROFINET IO, RT and IRT
  • Configure devices with GSDML, names and addresses

IEC 61850 Substation Automation: GOOSE, SCL and IEC 60870-5 course coverFree
FreePower systemsAdvanced

IEC 61850 Substation Automation: GOOSE, SCL and IEC 60870-5

The utility side of SCADA, taught the way a substation automation engineer meets it: the IEC 61850 object model and its logical nodes, SCL files from ICD through SCD to CID, MMS reporting against GOOSE against Sampled Values, the engineering process a system configuration tool follows, testing from office simulation through factory and site acceptance to maintenance isolation, and the IEC 60870-5-101 and 104 link that carries the substation to the control centre.

  • Read any IEC 61850 object reference down to the data attribute and name the logical node behind it
  • Tell ICD, SSD, SCD and CID apart and say who produces each and when
  • Decide whether a signal belongs on MMS reporting, GOOSE or Sampled Values

Computer Networking and CCNA 200-301 Prep course coverFree
FreeNetworkingBeginner

Computer Networking and CCNA 200-301 Prep

Learn computer networking from the ground up and prepare for Cisco's CCNA 200-301 exam: the OSI and TCP/IP models, Ethernet switching, IPv4 addressing and subnetting, VLANs and trunks, spanning tree, static routing and OSPF, IPv6, DHCP, DNS and NAT, ACLs and security basics, wireless, and network automation, with Packet Tracer labs throughout. Exam preparation only: the EDWartens certificate is not Cisco's CCNA, which is earned only by passing Cisco's 200-301 exam.

  • Explain the OSI and TCP/IP models and encapsulation, and choose copper or fibre for a link
  • Configure Cisco routers and switches from the command line in Packet Tracer, and secure and save them
  • Predict how a switch learns MAC addresses and how ARP finds a host

Questions

Do I need hardware?
No. Simulators and free tools (Modbus simulators, OPC UA servers, MQTT brokers) cover every exercise.
Which protocols are covered?
PROFINET, PROFIBUS, Modbus RTU and TCP, EtherNet/IP, OPC UA and MQTT, with the IT basics of IP addressing and subnets that every PLC connection needs.
