The course has been designed to familiarise Electricians, Technicians and Maintenance Engineers with little or no experience of S7 to the many different aspects associated with the operation and maintenance of Siemens S7 controllers.
Where possible, application specific exercises, actual drawings and programs listings are used to allow the students to gain the greatest possible benefit from the course. The practical experience on the course will provide knowledge on Program structure, editing, Hardware Configuration and Profibus networks enabling the student to perform maintenance faulting finding in the Siemens S7 software, on Siemens S7 hardware and on plant devices connected to Siemens S7 PLC.
To introduce students to the concepts and operation of S7 programmable controllers, including the following areas:
- Locate and replace faulty modules.
