S7 Service & Maintenance Part 3 (ST-7SERV3)

  • ST-7SERV3 S7 Service & Maintenance Part 3 (Siemens Certified Service Technician)


  • The third part of the SIMATIC S7 service training is based on the knowledge of the SIMATIC Manager gained in the SIMATIC S7 service courses 1 and 2, including SIMATIC STEP 7, HMI, connection of drives, and PROFINET IO. You will expand your knowledge in terms of program troubleshooting and error handling and learn how to display these errors in an operator control and monitoring system. The basis for this is to also interpret and expand existing programs in the programming languages Structured Control Language (SCL) and S7-Graph. You will set up communication between SIMATIC CPUs based on Industrial Ethernet.
  • Thanks to this comprehensive understanding, you gain new impetus and ideas to optimize your plant and can thus reduce or eliminate downtime in your entire plant.
