I have created a washing sequence of five cycles for a storage tank which is located on a farm. As soon as a selection switch is turns turned on the program starts running until the washing program is finished. The problem is that this specific farm has problems with mains voltage so some times while the program is running or even finished the voltage is cut off and then it is back it starts from the very first cycle.
The client isn't going to invest into fixing his mains so I want to find a way to fix it though Zelio.
Activating "Latching" in all the coils and timers of the program will make the program to continue from where it was before the power was cut off.
The problem is that if the washing sequence was already completed and the selection switch is used to start the cooling process (turning off Zelio) then washing is selected again it will not run because the "Latching".
It could be easily avoided by adding a push button to start the washing sequence after turning on the Zelio but I would like to solve using only software.
How to distinguish fast voltage drops from selection switch turning ON and OFF?
