You need to install both "Simatic Step 7" and "WinCC Flexible" Software from Siemens. Today, we'll try to make a connection between PLC S7-300 and your PC or Laptop using "
Ethernet" Port.

#Connecting a PG/PC via Industrial Ethernet
1). Make connection: LAN cable (Cat 5) to Ethernet Port (P1 or P2) on PLC S7-300 (CPU317-2 PN/DP) to your PC or Laptop.
 |
| Figure 1.2 - Ethernet Port (P1 or P2) |
2). Open "Simatic Step 7" Software: Options - Set PG/PC Interface... menu.
 |
| Figure 1.3 - Set PG/PC Interface |
3). Make sure: "Ethernet Network Connection.TCPIP.Auto.1" is Active. You can check through Diagnostics.., then click Test button (Results: OK).

|
4). Click on Properties... - Network Properties button to set IP address on your PC or Laptop. All PROFINET devices use the TCP/IP protocol. For this reason, they need IP address when operated on the Ethernet.

|
5). On Local Area Connection: double click - Properties - Internet Protocol Version 4 TCP/IPv4, and set your IP address and Subnet mask, then click OK.

|
6). Next: Go to PLC - Edit Ethernet Node... menu.

8). If we look at the configuration in HWI Config (Ethernet Address Assignment), to configure an Ethernet you must assign a MAC address or IP address to the Ethernet interface.
