Developing a Siemens S7-1200 Project from Scratch with TIA Portal

Automation has revolutionized modern manufacturing, boosting efficiency and productivity through the use of Programmable Logic Controllers (PLCs). The Siemens S7-1200 PLC stands as a prime example, offering manufacturers the ability to create tailored automation solutions. In this article, we explore the realm of PLC automation in manufacturing by detailing the process of developing a Siemens S7-1200 project from the ground up.

PLC Automation in Manufacturing

Automation has drastically reshaped the manufacturing landscape by replacing manual processes with streamlined, technology-driven systems. PLCs serve as the intelligence behind this transformation, orchestrating tasks such as machine control, input/output management, and intricate algorithm execution. The Siemens S7-1200 model embodies these advancements and is widely regarded for its pivotal role in industrial automation.

Developing a Siemens S7-1200 Project: A Stepwise Approach

Step 1: Project Planning and Conceptualization

The journey begins with meticulous project planning. Identifying the manufacturing process earmarked for automation, understanding required inputs and desired outputs, and mapping out the logical flow are key steps. Consider a scenario where automation is to be introduced into a bottling plant to facilitate filling and capping operations.

Step 2: Hardware Selection

Choosing the right Siemens S7-1200 model is crucial. Factors such as input/output capacity, processing speed, and memory play a pivotal role in selecting the appropriate model. In the bottling plant case, the chosen PLC model should accommodate the required digital inputs for bottle detection and digital outputs for controlling the filling and capping processes.

Step 3: Programming

Programming is the heartbeat of PLC automation. Siemens offers the user-friendly TIA Portal software, enabling engineers to craft the logic that defines the PLC’s behavior. Ladder logic, akin to electrical relay circuits, is commonly employed. In the context of the bottling plant, the logic might entail activating the filling mechanism upon bottle detection and subsequently initiating the capping process after a specified liquid volume is dispensed.

Step 4: Testing and Debugging

Rigorous testing and debugging are essential phases. Engineers simulate diverse scenarios to ensure the PLC responds accurately to various inputs and generates the expected outputs. Any discrepancies in the logic are pinpointed and addressed during this stage.

Step 5: Integration and Monitoring

Following successful testing, the PLC is integrated into the manufacturing process. The programmed logic now governs the automated process. Notably, the Siemens S7-1200 offers remote monitoring features, enabling engineers to oversee operations and troubleshoot issues remotely.


PLC automation, exemplified by endeavors such as developing a Siemens S7-1200 project from scratch, showcases the transformative potential of technology in modern manufacturing. Customizable automation solutions tailored to specific processes enhance efficiency, productivity, quality consistency, and cost-effectiveness. As manufacturing continues its evolution, PLCs like the Siemens S7-1200 will continue to be at the vanguard of innovation, driving industrial progress toward a future characterized by unparalleled efficiency and precision.

Video – TIA Portal V17 Siemens S7-1200 Project From Scratch

The video below shows an example of building a TIA Portal project from scratch.

Throughout the video, this is a longer video to show exactly what it takes to set up a PLC project in TIA Portal V17, and when I make these, there are no edits, when I start I like to show everything you may run into so you get a better understanding so please watch the whole video for the best knowledge share.

I hope that with the video above, using TIA Portal V17.

I will be putting together more programming videos and articles upon request, I already have several ideas and will be starting to add more videos to my YouTube channel which is Shane Welcher

I would love to hear what you guys think so far as I try to get this website whipped into shape.

Drop me a comment here or on my YouTube channel.
