0 l Cancels a current measurement
OSZ status Displays five different operating states
C0731
1 l Measurement completed
– The memory of the measured values is completely filled with data. The measured
values can be called by the PC.
2 l Measurement active
– A measurement was started with C0730 = 1. The FB waits for a valid trigger result.
3 l Trigger recognized
– The FB has recognized a valid trigger result. Depending on the trigger delay, the
saving of the measured data is not yet completed. It is completed automatically with
the entry of the last memory unit.
4 l Measurement cancelled
– Cancelling of the current recording of the measured values (C0730 = 0). The
memory of the measured values has been filled with data. The data can be called
by the PC.
5 l Read memory
– A memory of the measured data is currently read. No setting is possible in this
operating state.

C0732/4
l Links the measurement channels of the FB with the signals of the process environment
– Assignment of four measurement channels with any analog signals is possible. Enter
the corresponding signal number in C0732/1 ... C0732/4.
– Always start linking with channel 1, then channel 2 and so on. Unused channels are
automatically assigned with the signal FIXED 0%.
Configuration
OSZ trigger
C0733/1 Links the digital trigger input with a digital signal of the process environment
– The trigger input can be assigned with any digital signal. Enter the corresponding
signal number in C0733/1.
Trigger source Determines the trigger source
C0734
1 The source is one of the four measurement channels C0734/1 ... C0734/4

0 The source is the digital trigger input (C0733/1)
Trigger level C0735 -32767 ... 32767 l Determines the trigger level which the triggering releases when the threshold is
exceeded.
– The trigger level is monitored only when the triggering is done on one of the four
channels.
– The trigger level is not effective with digital triggering.
Trigger edge Determines the trigger edge which causes the release of the triggering.
l Triggering on analog input channel
– With a LOW-HIGH trigger edge, the analog trigger signal must exceed a defined
trigger level to release the triggering.
– With a HIGH-LOWtrigger edge, the analog trigger signal must fall below a defined
trigger level to release the triggering.
l Triggering on digital trigger input
– With a LOW-HIGH trigger edge the digital trigger signal must change from LOWto
HIGH to release the triggering.
– With a HIGH-LOWtrigger edge the digital trigger signal must change from HIGH to
LOWto release the triggering.
