Siemens S7

Learning to program Siemens S7 PLCs

This is the standard demo cell prepared for control via a Siemens S7 interface using TCP/IP (Put/Get). It can be connected to PLCSim Advanced or a real S7 PLC. The robot control is fully simulated. This model is ideal for training and learning S7 PLC programming in a realistic environment.

Interface Configuration

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

Configuring S7 Settings

To configure the connection:

1. Click the Settings icon (⚙️) in the toolbar.

2. Enter the following values based on your setup:

   • SiemensS7Interface.Adress → 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.
