@SherryHolmes Reading and writing blocks is possible for the 1200/1500 CPUs but it comes with some limitations. Just read the compatibility link here. For your problem these are the relevant information:

1. Only global DBs can be accessed.
2. The optimized block access must be turned off.
3. The access level must be “full” and the “connection mechanism” must allow GET/PUT.
