Siemens LOGO!
PLC online training

Automation Works, in partnership with TechnoSmart247 is now supporting an innovative on-line training course to provide you with an in-depth overview of the Siemens LOGO! PLC. No prior knowledge of PLCs are needed.

Course structure
The course consists of 10 online modules, with 3 practical assessments. Each module consists of:

  • Videos with interactive questions
  • One or more assignments submitted online and individually marked

The practical assignments are completed over 2 days at one of our training facilities. Siemens LOGO! PLCs and FESTO Didactic equipment are used. The facilitators will be available for any questions/queries for the duration of the course.

A detailed description of the curriculum is provided below.
