Duration: Prerequisites:
Aims:
5 days Ideally delegates should have a basic understanding of PLCs or have attended one of our Introductory or Multi-Skill courses & have some familiarity with Microsoft Windows. This course is for people with limited PLC knowledge & experience with no prior knowledge of Siemens S7-300/400 PLC systems. Siemens S7-300/400 FLPS is a “less-technical” course which targets less confident maintenance personnel who have limited PLC knowledge & experience & covers First-line Siemens S7-300/400 Practical Skills. The course equips maintenance personnel with the essential basic knowledge & skills to connect a laptop, get on-line, search within a program, understand simple Ladder program code & be able to Compare, Back-up or Re-load a program. This course is different from the regular Level 1 as it skips over a lot of the sometimes confusing theory which, whilst important, confuses those less familiar with PLC concepts. The FLPS course avoids some of the more difficult-tograsp concepts which are again important but without which maintenance people can still be confident & undertake a range of useful & essential maintenance & troubleshooting duties. Typical topics include (the top 20): 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20.
