PLC CONTROL 

When fountain is of a dynamic type, as is usually the case with dry deck and interactive fountains , it needs a control system that manages the effects of water, lighting and sound (in the case of musical fountains ), as well as the synchronization among all these aspects. 

The chosen system is not only determined by the classic jets used in the dry source, but also by other factors: 

• The  type of dynamism of the source (obtained by a previously recorded operating sequence that the device must execute cyclically) 
• The  synchronization between the water features and lighting 
• The fact  that the source is musical or not. 
• The  economic valuation carried out based on the number of elements that the system will be in charge of controlling. 

To manage the control of these factors in dry sources,  there are two types of technology that give rise to the respective control systems. Next, we are going to see the control systems based on PLC.
