Can I programm this task?
Socket 1: freshwater pump
Socket 2: seltwater pump
Level sensor turn on both Socket (1 and 2)
If sensor salinity (conductiv) >45 then Socket 2 (seltwater) turn off

logic 2 => level 1 AND decrease salinity attach logic2 to socket 2
logic 1 => level 1 AND increase salinity attach logic 1 to socket 1
tks a lot
Hi Andrey and blahenazo
This will not work correct. Because there is a minimum Hysteresis around, in Andrey's case 45, where the controller will not trigger conductivity increase or decrease, even if the level sensor is asking for water (hysteresis can not be set to zero on the ProfiLux).
Another way to do it:
logic 1 = "level 1" AND "Conductivity Decrease" > attach logic 1 to socket 1
logic 2 = "level 1" AND "Conductivity Decrease [inverted]" > attach logic 2 to socket 2
In logic 2 click the "invert" box under the "Conductivity Decrease" field.
Then you eliminate the hysteresis, because logic 2 will function as "Conductivity Increase" as soon as "Conductivity Decrease" are not true.
