Prerequisites (Mandatory)
This is an advanced training course. To successfully follow the lessons, you must complete the following prerequisite courses before enrolling:
These courses provide the essential knowledge required for this training. Enrollment without the prerequisite knowledge is not recommended, as many concepts will not be explained again.
Recommended Learning Path
- DIGSI 4
- DIGSI 5
- Industrial Communication
- IEC 61850 Configuration
- Substation Automation System (SAS)
- Siemens Bay Control Unit (BCU) ← This Course
- SICAM PAS
- SICAM SCC
Important: The Siemens Bay Control Unit (BCU) course is compulsory before taking the SICAM PAS and SICAM SCC training packages. These courses are designed as a continuous learning path, with each course building on the knowledge gained in the previous one. Skipping any prerequisite course may make it difficult to understand the advanced topics covered in later courses. You can enroll in this course. If you have completed all the mentioned courses, please contact us and enroll in this course.
Course Topics:
- SAS fundamentals
- Siemens SAS architecture
- SIPROTEC 4 BCU engineering
- SIPROTEC 5 BCU engineering
- Real-world case studies
It also provides a natural bridge to your next courses on SICAM PAS and SICAM SCC, making the learning path continuous.
