You can set the retentive memory bytes in the CPU properties, Retentive Memory tab. See attachment. The data blocks are generally retentive with battery backup. See the online help for a detailed description. I cannot think of any other way to view the memory except via VAT. You could transfer the entire memory area to a data block using SFC20: Block Move and view the memory status in the DB. But I do not see any great advantage in doing this.

pici_c: The pulse flags can be defined in the CPU properties Cycle/Clock memory tab. The assigned frequencies are described in the online help. See attachment. The first cycle flag (for each OB), you have to create yourself in the program. BTW, OB2 to OB9 are not used in S7. In S5 they are used for interrupt processing.
