Hi,

my goal is to distribute water to patients using 2 drums (preffilled  with water) with one pump.the principles is that the pump work in 2 senses of rotation(  i find a solution that i connect an output from the Logo Q1 to the Input on the pump so i can switch the direction of rotation with my switch button).

i try to do step 1(file etape1) in this project that i control the level of one drum by pressure transducer and its working.now is there any help or suggestion to do my scenario in this project:

-the pump will turn on,  untill the the first drum will be level low  ( valve 1a and 1b are openend; 2a and 2b closed)

-after that, the pump reverse rotation and trun on till the second drum will be low level ( valve 2a and 2b are openend; 1a and 1b closed).

the drum dimension (34inch*24inch)

level low : 4inch

valve types: proportionnel valve 2-10V (analog output AQ)

thanks

Hi ,

yes its the same topic as reverse rotation of pump...but now i can reverse it from the logo using this pump(from the input )...so my question is is that some exemples of programme that could help me with that concept.

thanks.

sorry, I have not done it on purpose but i try to focus on that next time...i just work hard to find solutions for that in simens exemples or here...anyway, it will be plaisure if u give me some helps or suggestions as exemples for programm..

thanks i appreciate.
