# Siemens S7

**Master Siemens S7 PLC programming with a complete industrial automation training environment featuring a realistic demo cell and comprehensive TIA Portal project.**

This ModelZoo entry provides a complete S7 training experience, combining:

* **Complete demo cell simulation** with robot, CNC machine, and conveyor systems
* **Full TIA Portal project** (S7-1500 compatible) with structured programming examples
* **Real-time PLC communication** via TCP/IP (Put/Get) for authentic industrial experience
* **Virtual commissioning setup** compatible with PLCSim Advanced and real S7 hardware

## Demo Cell Overview

The training environment simulates a modern manufacturing cell featuring:

* **Entry conveyor** with part detection sensors
* **6-axis robot** for pick-and-place operations with simulated kinematics
* **CNC machining center** with door control and machining simulation
* **Exit conveyor** for processed parts
* **HMI control panel** with operator interface elements

The automation sequence demonstrates typical industrial workflows: part arrival, robot loading, machining operations, robot unloading, and part discharge. All operations are coordinated through the S7 PLC program provided in the complete TIA Portal project.

## Interface Configuration

Before connecting to a Siemens S7 PLC, you need to configure the IP address, rack, and slot of the controller.

<figure><img src="/files/UrmfnpwJ9e2TP3ZmduoA" alt=""><figcaption><p>Configuring S7 Settings</p></figcaption></figure>

To configure the connection:

1. Click the **Settings** icon (⚙️) in the toolbar.
2. Enter the following values based on your setup:
   * **SiemensS7Interface.Address** → The IP address of your PLC (e.g., `127.0.0.1` for PLCSim Advanced).
   * **SiemensS7Interface.Rack** → Usually `0`.
   * **SiemensS7Interface.Slot** → Typically `0` for PLCSim Advanced, `1` for physical PLCs.

> 📘 Refer to your TIA Portal project or PLC documentation to confirm the correct rack and slot values.

## TIA Portal Project
