2PULSE
5.1 Product Overview
Operating Modes
● "Pulse output" operating mode
● "Pulse width modulation" operating mode
● "Pulse train" operating mode
● "On/Off-delay" operating mode
● "Frequency output" operating mode
Functions
● Measurement of current in the "Pulse width modulation" and "Pulse train" operating
● Direct control of the digital output by means of the control program
● Error detection/diagnostics (short circuit of the digital output and encoder supply)
● Parallel connection of both channels of the 2PULSE to achieve a higher output current
● Programmable response to CPU/master STOP
Configuration
In order to configure the 2PULSE use one of the following options
● STEP 7 as of Version V5.4 SP4 with the HSP 2072 (Hardware Support Package from the
● A GSD file (http://www.automation.siemens.com/csi/gsd)
Firmware update
In order to extend the functionality and eliminate errors, firmware updates can be
downloaded to the operating system memory of the 2PULSE by means of the STEP 7 HW
Config software.
Note
When you launch the firmware update, the old firmware is deleted. If the firmware update is
interrupted or canceled for any reason, the 2PULSE will no longer function correctly as a
result. Restart the firmware update and wait until it has completed successfully.

A pulse with variable pulse duration is output at the digital output of the 2PULSE.
A pulse sequence (square wave signal) with defined time period and variable
pulse/pause ratio is output at the digital output of the 2PULSE.
A variable number of pulses with defined time period and pulse duration is output at the
digital output of the 2PULSE.
The signal pending at the digital input DI is output with an on/off-delay at the digital output
DO by the 2PULSE.
A square wave signal with variable frequency is output at the digital output of the
2PULSE.
