=============================

In this video, you will learn all the basic but practical information you need to know about the popular S7-1200 PLCs.

You will also gain a good understanding of the kinds of industrial applications they are suitable for.

Let's start with the basics of what an S7-1200 PLC is. It's a type of programmable logic controller manufactured by Siemens, used to control and automate industrial processes.

The S7-1200 PLC has two main components: the hardware and the software.

The hardware includes the power supply, central processing unit (CPU), input/output modules, and communication modules.

The software used to program the PLC to perform specific functions based on input signals from sensors and switches is called TIA Portal, which is also developed by Siemens.

- The 1211C is a starter model for the S7-1200 PLCs. It has less memory and fewer ways to communicate, but it still works well for small and medium automation projects. If you want to create an HVAC system, the 1211C could be a good choice for you.

- The next type of S7-1200 PLC that I will talk about is called the 1212C. It's a great choice for slightly bigger automation applications, like controlling the temperature of a medium-sized industrial furnace. The 1212C also supports PID control functions.

- The 1214C is a popular choice for applications that need more advanced automation, like moving materials around, running pumps, or managing small processes. With the 1214C, you can also create PID control functions with more advanced features.

- CPU 1215C is a good option for large automation tasks. By large automation tasks, I mean tasks that usually need high-speed processing and advanced communication capabilities such as complex process control systems, motion control systems, and large material handling systems.

- The 1217C is similar to the 1215C but it has more inputs and outputs. It's also faster, which is important for applications that need to gather data quickly. One example of an application that needs a faster PLC is high-speed data acquisition.

- The 1212FC, 1214FC, and 1215FC fail-safe models are designed not only to control machines and equipment but also to keep people safe. In places like oil rigs or factories where dangerous things can happen, it's important to have an extra layer of protection to prevent accidents.

The letter "C" at the end of the S7-1200 PLC models indicates that the PLC has a compact design. Even though they're small, they have built-in inputs and outputs. But, you can always add more input/output modules to them if you need to.

In terms of communication ports, all of the S7-1200 PLCs come with PROFINET ports that help them communicate with other machines.

But sometimes, you may need to use a different type of port like Profibus-DP, I/O Link, or AS-i to make them work with other machines. To fix this problem, you can add a communication module to your S7-1200 PLC.

So much needed videos for PLC engineers

[murillogumiero]

Lack important information regarding expansion cards limitations in each size. Great video overall.

[zouhairraquibi]

Thanks guys I hope you add Schneider PLCs to your series, thanks again and keep the great and awesome work.

[orsanbogdan]

thanks for your videos, as a beginner in the field, it helps me a lot

[syufrijal]

Amazing explanation of 7-1200 PLCs...very helpful

[MarsShare]

I hope that will be a full course in s1200 plc

[AnasAl-Dhafiri]

Many thanks for your video and clear explanation.

[aktsarabdikar]

Hey Realpars, thanks for the education
Question, does S7-1200 have a special communication module for OPC UA?

[lodyyy-npjd]

we need more about PLC DCS GE SIEMENS i hope you create a playlist !!!
and thank you so much (:

[sarahlabidi]

Thanks you very much for this beautiful video 😊😊😊

[greatestever]

i'm in my last 2 months of instrument tech school and were doing PLC&DCS lol

[adamabbott]

Hi, may I ask one question about PLC. How does PLC measure digital value. How does PLC know it js open status or close status ?

[kierjohnalba]

Hello, I'm from Philippines. Can I make a request for the tutorials of Siemens 3rp1560-1sp30 how is it works... Thanks.

[aminebenhabiba]

we need more of s-1200 and also 1500 if you can

[edsonlopes]

Please, is it possible to back up the software and hardware of the Siemens S7-1200 plc programmed with tia potlrtal V11, when I searched on the internet, tia portal v11 does not back up hardware, my equipment is working in good condition, I just want to have a PLC If anyone can help me, I will be able to pay for the help.
