3.2.47 Oscilloscope function (OSZ)

3−141

EDSVS9332S−EXT EN 2.0

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
