Functions
3.2.2.1
Function: High-speed output
The function "High-speed output (0.1 A)" enhances the signal clock of the digital outputs
(DQ0 to DQ7). Less delay, fluctuation, jitter, and shorter rise and fall times, occur at the
switching edges.
The function "High-speed output (0.1 A)" is suited for generating pulse signals in a more
precise clock, but provides a lower maximum load current.
For the PWM and frequency output modes, select the high-speed output of the channel in
STEP 7 (TIA Portal). You can also change the parameter assignment during runtime with the
help of the program via the data record.
High-speed pulse output (high-speed output) is available for the following operating modes:
●
PWM
●
Frequency output
●
PTO (the pulse outputs for the PTO mode are always "High-speed output (0.1 A)")
