Oscilloscope

*

This is an element to display the temporal development of bits and analog values (16 bit). For displaying analog values, you have to adjust the min and max value appropriately. If the min value is less than zero the PLC word is interpreted as integer and the max value is limited to 32.767.

 

If you want to display DINTs or REALs you have to recalculate the values into words in the PLC program. For that purpose you can use the FC51 resp. FC52 in the directory IECFuncs. We recommend to place this kind of calculations that is needed for simulation purposes only in the OB 2 or OB 3.

 

With the editing field ‘Time/Div’, you can stretch or compress the display in temporal direction. Usually it is not necessary to adjust this value. Use this setting together with the changing of the size of the oscilloscope to get a representation which is appropriate to your application.

 

With the editing field ‘recording rate’ you can modify the recording rate of data. A time, shorter than the simulation rate, has no effect. The higher you adjust this value, the smaller is the temporal resolution for short events, but the longer is the recording period.

Please note the difference to the setting Time/Div, with this just the representation of the already recorded values is influenced on the monitor.

 

There are no further trigger possibilities or other adjustments, but have a look at the speed trigger.
