Function DescriptionSelectionCode
Memory size C0744 0 ... 6 Set memory depth of the data memory
– Max. size of the data memory: 8192 measured values ¢ 16384 bytes (C0744 = 6)
– Min. size of the data memory: 512 measured values ¢ 1024 bytes (C0744 = 0)
– Changing the memory depth from 512 to 8192 measured values/step
– A memory depth which is optimally adapted to the corresponding measuring task
reduces the data transmission time.

Information on saving the measured values in the data memory
The FB saves the data in a ring format. For reconstructing the chronological signal
sequence the following three "graphic points" are marked.
C0749/1 Measured value no. of the instant of abortion
C0749/2 Measured value no. of the instant of triggering
C0749/3 Measured value no. of the instant of completion
