A modular automation solution for flexible irrigation of plants with S7-1200
Do you want to efficiently water one or more areas? This application example enables you to water up to five different zones automatically. If necessary, you can extend the number of zones as needed. You will always have a clear overview of your irrigation system and only use as much water as is actually need. You take the water from a water tank or the public water supply system.
Efficient, simple and time-saving
Your benefits when you use this application example.
Needs-based watering helps you save precious resources.
Simple operation via Panel or web server
A user-friendly operating concept enables very simple operation for anyone, even while you are on the road from your smartphone or tablet.
Automation saves time
The selection of the right components and their programming can be very time-consuming. Use our recommendation and spend the time that you save by using the application example for more important things.
Thanks to its modularity and flexible expandability, you can use the application example for a wide variety of irrigation tasks.
Some examples for the possible uses:
- Private and public gardens
- Sports arenas
How does it work?
The S7-1200 controller starts the irrigation of the individual zones once a day at a specified time for a previously set time period. The zones are watered one after the other. You can manipulate the program sequence (manual operation) via a web browser (e.g. on a smartphone) or by using a Touch Panel. The water is either taken from a water tank using a pump or from the public water supply. The water tank can be monitored with the help of a level sensor.
