2PULSE
5.2 Example: Starting 2PULSE
Configuring with STEP 7 using HW Config
You must first adapt the hardware configuration of your existing ET 200S station.
1. Open the relevant project in SIMATIC Manager.
2. Open the HW Config configuration table in your project.
3. Select the 2PULSE from the hardware catalog. The number 6ES7 138-4DD00-0AB0
4. Double-click this number to open the
5. Save and compile your configuration, and download the configuration in STOP mode of
Integration into the Control Program
Create block FC101 and integrate it in your control program (in OB1, for example). This
block works in this example with the MB10, MB20 and M30.0 memory bits.
In block FC101, the start address of the inputs and outputs of the 2PULSE is 256. If
necessary, take the address from the hardware configuration.
This block sets a pulse duration of 5000 ms and starts pulse output as soon as you have
issued the enable using your control program (SW_ENABLE=1).
