If we still need in the other CPUs also, then we need to wait for a while. Yes, the new S7-1200 FW3.0 versions have more memory, and more retentive memory, plus a battery backup option (as a signal board) that should hold data for up to a year if I read the documentation correctly. The S7-1215 on my desk looks ready to go solve some problems from 2 years ago. Hello huggy_d1, The retentive memory area is strored in theFlash within the CPU, which doesnot need a battery at any point in time, unlike S7-200 (which uses a super-cap). The battery board module will serve a backup to retain the RTC of the CPU, which has hardly things to do with the retentive memory. In retentive memory I foresee a bottleneck if the requirement is more than 10KB in big projects.
