Proper cable to connect to a S7-200

Is there anyother cable that will work other than the "Intelligent RS 232/PPImulti-master cable" or the "Intelligent USB/PPImulti-master cable". I am not sure if there is an ethernet card istalled to enable TCP/IP.

S7-200 does not have Ethernet built in, but once you program it with a serial connection, you can configure the IP address. Once configured, you can program over the Ethernet connection.

The PC/PPI cable is in fact a simple data-driven RS232/RS485 converter. Any converter that doesn't need handshaking lines can do. I even tried it with an AIC+ from Allen-Bradley and that seems to work as well. I wouldn't recommend this interface, because it's about the same price (or even slightly more - at least over here) than the original Siemens cable, and you have to wire the RS485 side yourself.

Kind regards,

Thats it? Just convert the 232 to 485?

Any comment about this? Is this really that simple? thank you.
