I am new to PLC’s and I am trying to program a small Siemens LOGO PLC with the use of their LOGOSoft software in the wiring diagram section
I am trying to design a simple alarm system for low water level on a tank.
the tank will have a float switch, when the level drops it closes the switch and sounds an alarm and flashing light.
What I wanted to do is when the switch closes, and both the light and siren is running, I want to be able to silence the siren for 5 minutes and if the tank level is still low the siren will sound again.
I have been trying to figure out what type of timer to use but I have been struggling to find the right way to do it.
Any Help would be greatly appreciated.
