Functional description
Function Code Selection Description
OSC mode Controls the measurement in the co ntrolle r
C0730
1
•
Starts the recording of the measured values
0
•
Cancels a running measurement
OSC status Displays five different operating states
C0731
1
•
Measurement completed
– The memory of the measured values is completely filled with measured data. The
measured values can be accessed via the PC.
2
•
Measurement active
– A measurement was started with C0730 = 1. The FB is waiting for a valid trigger
event.
3
•
Trigger detected
– The FB has detected a valid trigger event. Depending on the trigger delay the
saving of the measured data is not yet completed. It is automatically completed
with the entr y of the last memory unit.
4
•
Measurement cancelled
– Cancel of a running recording of the measured values (C0730 = 0). The memory of
the measured values is filled with the da ta that has just been measured. The data
can be accessed via the PC.
5
•
Read data memory
– The measured data memor y is being r ead at the moment. No settings are possible
in this opera ting state.
Configuration
OSC channel
1 ... 4
C0732/1
to
C0732/4
•
Links the measuring channels of the F B with the signals of the process environment
– The four measuring channels can be assigned with any analog signal. Enter the
corresponding signal number into C0732/1 ... C0732/4.
– Always start linking with channel 1, then channel 2 and so on. Unused channels
are automatically assigned with signal FIXED 0%.
Configuration
OSC trigger
C0733/1 Links the digital trigger input with a digital signal in the process e nvironment.
– The trigger input can be assigned with any digital signal. Enter the correspondi ng
signal number into C0733/1.
Trigger source Defines the trigger source
C0734
1 Source is one of the four measuring channels (C0734/1 ... C0734/4
0 Source is the digital trigger input (C0733/1)
Trigger level C0735 -32767 ... 32767
•
Defines the trigger level which ac tivates the triggering when the threshold is
exceeded.
– The trigger l evel is only monitored when the triggering is done on one of the four
channels.
– The trigger l evel is not effective with digital triggering.
Trigger edge Defines the trigger edge which activa tes the triggering.
•
Triggering on an analog i nput channel
– With a LOW-HIGH trigger edge the analog trigger signal must exceed a defined
trigger level to activate the triggering.
– With a HIGH-LOW trigger edge the analog trigger signal must fall bel ow a defined
trigger level to activate the triggering.
•
Triggering on a digital trigger input
– With a LOW-HIGH trigger edge the digital trigger signal must c hange from LOW to
HIGH to activate the triggering.
– With a HIGH-LOW trigger edge the digital trigger signal must change from HIGH to
LOW to activate the triggering.
