# Configuring the PLC Hardware

Configure the PLC hardware with SIMATIC Manager by following the below steps:

1. Launch SIMATIC Manager, and create a new job.

2. Add a new SIMATIC 300 Station to the job. To do so, right-click on the job list on the left pane of the user interface, then select the Insert New Object => SIMATIC 300 Station option.

3. Open the hardware configuration (HW Config) menu by clicking on the newly-added SIMATIC 300 station, and then double-clicking on Hardware in the right pane of the user interface.

4. Drag and drop a Rail to the HW Config from the Catalog on the right side of the user interface. The Rail is in the SIMATIC 300 => RACK 300 => Rail menu.

5. Drag and drop the correct CPU type from the Catalog to the Rail. In this example, the following CPU is used:

   SIMATIC 300 => CPU-300 => CPU 315-2 PN/DP => 6ES7 315-2EH13-0AB0 => V2.6

6. Set the IP address, subnet mask and gateway for the CPU, then add a subnet to the network by clicking on the New button of the dialog.

Note:

These settings can be accessed and modified later by right-clicking on PN-IO, selecting the Object Properties option, and then clicking on the Properties button.
