Siemens S7 1500 PLC Hardware Setup| IO Modules, Connectors and Power Ratings Pt. 2

Описание: Unboxing a Siemens S7-1500 is only the start. In Part 2 of this series, we move past the CPU to understand the critical hardware components that form the backbone of your automation system. Before we touch a single wire in Part 3, you need to understand how these modules truly work.

In this video, we break down:
1. I/O Modules & Bus Connectors: How backplane communication works and why the bus connector is the most important "small" part in your rack.
2. Power Module (PM) vs. System Power Supply (PS): Understanding current ratings and how to choose the right power for your load.
3. Hazardous Ratings: A breakdown of Class I, Div 2 and Zone 2 certifications—essential for oil, gas, and chemical industry applications.
4. The Coding Element Mystery: Why that little plastic "mechanical latch" is your best friend when preventing wiring errors.
5. The 4MB SIMATIC Memory Card: Is it enough for your project?
6. The DVD Included: Why you should NOT try to install TIA Portal from this disk (and what it’s actually for).
