System requirements: see auto.spy analyzer and Drivers

Limitations of the demo version: In the demo version, all the features of the full version are available, but a maximum of two signals from one data source can be recorded for an unlimited time. Video recording is limited to one minute. The display is also limited to showing the first two signals of any signal track document.

32-bit version: We recommend using the 64-bit version of auto.spy whenever possible. However, if you want to communicate with SIMATIC S7 controllers via the Siemens PG/PC interface or collect data from SIMATIC S5 controllers, or if you are still using older operating systems such as Windows XP, you will need the 32-bit version of auto.spy. Both versions of the application can be used in combination, since the auto.spy documents remain interchangeable.
