I have got a Siemens PLC (S7 315-2 PN/DP PLC), which has got a built in Ethernet port.

I want to establish communication between PLC and my PC through TCP/IP (VB.NET based program).

If you want to send data based on events you could also use the 315's build-in Ethernet cummunication blocks and send a data packet (like emulated XML or JSON) each time something interresting happens. I did it a few times and it works very well.
如果您想根据事件发送数据，您还可以使用 315 的内置以太网 cummunication 块，并在每次发生相关事件时发送数据包（如模拟 XML 或 JSON）。我做了几次，效果很好。
