A color mixing plant is controlled with a SIMATIC S7-300 in the automatic or in the manual mode. In 
the "Automatic“ mode, the three tanks are filled with a two step control.  At the minimum level, the 
inflow valve opens automatically, and after the maximum level is reached, it is closed again. After the 
start button is operated, the specified program is executed: first, the outflow valves are opened and 
the container is filled from tanks with the specified amounts. After the outflow valves are closed, the 
mixer motor is started. After the mixing time has expired and after a short idle phase, the outflow 
valve of the container is opened and the finished color mixture is drained.  When the container is 
empty, the lamp of the start button lights up, and a new color mixture can be started. 
In the "Manual“ mode, the automatic outflow is canceled, and all valves as well as the mixer motor 
can be operated manually. The lamps in the buttons for manual operation are lit. 
 
Note 
The specified amounts and the time base are determined by the program. If you want another color 
mixture, the specified amounts and the time base have to be changed, and a new program has to be 
loaded to the controller.
