Signal Generator - HBM ClipX Bedienungsanleitung

If either the target value or actual value is invalid, the controller stops and the value is
marked as invalid. However the output retains the last value. In the case of Enable by: 0
the controller is reset and the value of Y
the Start/Stop with signal.
7.4.2.17 Logic modules
The calculation provides various logical (Boolean) functions: AND, NAND, OR, NOR, XOR,
XNOR and NOT. Two function blocks are available, though all four possible inputs are
always used for the AND, NAND, OR and NOR functions. Consequently, you cannot use
these functions independently of each other and of others. The XOR, XNOR and NOT
functions each use only two of the four inputs, and have two outputs each. The other
functions have only one output. The output(s) are generated in the flags of the calcula-
tion channels – see

7.4.2.18 Signal generator

This calculation generates a periodic signal, for example a sine wave. Determine the
desired frequency, amplitude and, if applicable, an offset. Signal forms available are
sine, square wave, triangle, counter, constant and (white) noise. The signal on
Start/Stop with together with Start on determines whether the selected function will be
outputted. When Start on: High level) is set, on a Low level (0) the output is stopped and
the Offset value is outputted. When the signal switches back to High (1), a new output
period begins.
Use 100 Hz (1/10 of the update rate) as the maximum frequency, otherwise the
output signal will not be formed from enough points. This results in a distorted
curve shape (stairway effect) for a sine wave.
Example: Sine with amplitude 50 and offset 50
The amplitude fluctuates sinusoidally between 0 and 100 at the set frequency.
If the result is outside the number range, NaN (not a number) is outputted.
Counter function
At an offset of 0 the counter generates a number between -Amplitude and +Amplitude
that is incremented by one each time by the update rate (1000 Hz). Any entered fre-
quency is ignored.
