High-speed outputs
For short pulses and maximum output accuracy, configure the digital outputs at interface
X142 as high-speed outputs.
The digital outputs are then operated as rapid push/pull switches, which are switched
alternately to 24 V DC and ground. This enables very steep edges and extremely short output
delays.
Digital outputs as high-speed outputs are particularly suited to the operating modes timer
DQ, oversampling DQ and pulse width modulation (PWM).
Note
Notes on interconnection
When you use the digital outputs at the X142 interface as high-speed outputs, the current-
carrying capacity is reduced from 0.5 A to 0 4 A.
Please note also the information on input interconnection for high-speed outputs in the
SIMATIC Drive Controller manual
(https://support.industry.siemens.com/cs/ww/en/view/109768445).
Expansion of technology functions with technology modules
For solving technological tasks, powerful distributed technology modules are also available
that operate largely autonomously and reduce the load on the CPU.
