Merhaba, 

Simatic Manager ile S7300 ve s7400- PC bağlantısı için (back up alma, online olma vb) ethernet bağlantısı kullanılabilir mi? Yoksa bu plcler için  USB/MPI kablosu  kullanmamız mı gerekiyor?

Hello,

Can ethernet connection be used for S7300 and S7400-PC connection (backup, online, etc.) with Simatic Manager? Or do we need to use USB/MPI cable for these plcs?

Merhaba Mukhem,

Siemens otomasyon forumu dünyanın birçok ülkesinden programcıların ilgisini çekiyor ve birçoğu Türkçe anlamıyor.

The answer to your question is: yes, you can use Ethernet to download, upload, and program the S7-300 and S7-400 PLCs, if you have the correct interface on your system.

- If your CPU has an RJ45 connector, connecting to an integrated Profinet port (the CPU part number will contain a -PN identificator), then you can use an Ethernet connetion between Step 7 and the CPU, with the PC's Ethernet cards.

 - If your S7-300 has a CP 343-1, or your S7-400 has a CP 443-1, even if he CPU does not have an integrated Profinet port, you can setup an Ethernet connecton between Step 7 and your CPU, using your computer's Ethernet card, by connecting to the CP.
