Function DescriptionSelectionCode
Trigger delay The trigger delay defines when to begin with the saving of the measured values with
regard to the trigger time.
C0737
-100.0 % ... 0 %
• Negative trigger delay (pre-triggering)
– Defines a percentage of the whole memory content. This part of the memory
content is filled with measured values before the triggering (see Fig. 7-195).
0 % ... 999.9 % • Positive trigger delay (post triggering)
– Defines a percentage of the whole memory content. The saving of the measured
values after triggering is delayed by this part of the memory content (Fig. 7-194).
Sampling period C0738 1 ms ... 10 min • Setting of the sampling period
– The sampling period is the time between two measurements
– The measurements are carried out simultaneously for all channels (e. g. i s
measured value at channel 1 is measured at the same time as a measured value
at channel 2, 3 or 4.
– The sampling period can be set in steps of 1, 2 and 5.
Number of
Channels
C0739 Number of channels used for measurements.
Read data
The code is required if the GDC is not used for the visualisation.
memory
C0740/1 0 ... 16383 • Defines the starting point for reading the data memory and thus enable s the memory
array to be deliberately accessed.
– In order to read the data memory bit by bit (e. g. reading only the measured value
of a channel or reading with reduced memory depth), the starting point can be
changed.
C0740/2
1 • Enable “Read memory”
– Enables the access to the memory to read the data
0 • Inhibit “Read memory”
– Inhibits the access to the memory. The access must be inhibited after e very
reading of the data

C0741/2 Data memory size (1024 ... 16384 bytes)
C0741/3 Data width of the measured values (1 byte / 2 bytes)
C0741/4 Number of the available measuring channels (1 ... 4)
Memory size C0744 0 ... 6 Set memory depth of the da ta 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 of 512 ... 8192 measured values/step
– A memory depth which is optimally adapted to the corresponding measuring task
reduces the data transmission time.
Information on
saving
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
