Note!
When the oscilloscope is integrated into the IEC 61131 program (DDS), it
requires a permanent calculating time of 100 ms. Check in the task monitor, if
enough calculating capacity is available.
The following steps must be carried out to activate the oscilloscope in the DDS:
1. Enter the system block OSC_Oscilloscope into the control configuration.
2. Read the system block input OSC_bUsed into the program organisation unit of the
program type.
Thus the oscilloscope is called in the input process of the tasks which also contains the
program wit the entry mentioned. The minimum sampling rate is determined by the task
which includes the oscilloscope.
Examples
ƒ AWL:
LD OSC_bUsed
ST A
ƒ ST:
A := OSC_bUsed
