**An overview of S7-200**

The S7-200 CPU integrates a microprocessor, input circuits and output circuits and a power supply unit in a compact housing to produce an efficient Micro PLC. After installing your software, the S7-200 provides the logic needed to track and control input and output devices in your application.

In S7-200, there are various types of CPUs are available in market such as CPU 221, CPU 222, CPU 224, CPU 224XP, CPU 226. We can add up to 7 expansion modules depends upon the CPU.

Check the below table for more details.

We need to do a hardware configuration to add the expansion modules to the CPU. In this article, am give you an exact idea to configure the CPU for adding expansion modules

**How to do Hardware Configuration of S7-200 ?**

**Step 1)** Open Step7- MicroWin Smart

Note: Before that, you have to set the IP address

For that, Go into Control Panel \> Network Settings \> Change Adapter Settings \> Select the appropriate adapter \> Change IPv4 Settings. The PLC is at 192.168.2.1, so by setting our IP to 192.168.2.30.

**Step 2)** Double click on **CPU ST40**
