python-snap7: Reading DB1 of S7-1200 shows error "CPU : Address out of range"
I am reading s7-1200-1214C-1AG31 whose firmware version is V3.
I close all the protection method in portol and create an unprotected DB block as snap7 documentation said.
But when I tried to use “read_area(S7AreaDB,1,0,2)” to read it , it shows error:
snap7.snap7exceptions.Snap7Exception: b'CPU : Address out of range'

Did you use the optimized data block? @Zhxhh Because since S7-1200 there is a new functionality in TIA, that optimitzes the memory. Maybe you can try to unclick it.
