Hi All,

Not entirely new to Logo, but i seem not to be able to solve this by myself.

It's for a pool pump. Depending on 4 input switches my pump has to change its working mode. It has 4 digital inputs. I have 4 inputs on my logo which when active should activate one output but at the same moment has to first turn off all 3 other outputs. This goes for every input.

So in basic if input i1 is on, output Q1 is on and output Q2,Q3 and Q4 needs to be off. If input I2 is on, output Q1, Q3 and Q4 needs to be off. etc.

It's important that before turning an output on, we need to be sure that the other outputs are off. I don't know how fast the Logo is in switching, so maybe a pause between off and on?

Can somebody put me in the right direction here?

Kind regards,

Erik

Hi,

The 4 inputs are F1-F4 on a HMI screen

Ah.. thanks for the update. It almost does what i need..

when input 1 is on, and i turn input 2 on. Input 1 does not turn off etc. 

Is it possible to do that? Or do i need to change the hmi command from setbit to another?
