The 6ES7298-0AA40-0AA0: This is a training bundle for the SIMATIC S7-200 line—five CPU222 DC units, five USB/PPI programming cables, and the STEP 7 Micro/WIN software in six languages (German, English, French, Spanish, Italian, Chinese). It was put together by Siemens as a one-shot educational package, with availability originally limited until the end of 2015.
Compatibility note
This is strictly an S7-200 training package. It will not work with an ET 200S system (like the 6ES7151-3BA20-4AB1 training bundle) or any other platform. The CPUs are DC-powered, so no AC power supply—plan on a 24 VDC source for each CPU222.
