Operator Control with WinCC flexible 2005

At the color mixing plant, the program was changed with the programmer each time the mixing ratio 
changed. Since such changes are not only time consuming, but also dangerous if wrong entries are 
made, it was decided to expand the color mixing plant with a TouchPanel TP177B. 
 
By using the panel, the following requirements are to be met: 
 
- 

The color mixing plant can also be operated with the panel. 

- 

The levels of the tanks and the container are to be displayed as a bar and also as a numerical 
value. 

- 

The motion of the mixing motor is to be shown graphically. 

- 

The specified amounts are to be entered on the panel. 

- 

The minimum and maximum levels of the three tanks are to be entered in separate tank 
graphics. 

- 

The operating modes can be switched using the panel; the respective operating mode is 
displayed on the panel. 

- 

The completed mixtures are to be stored on the panel as recipes; the operator only has to select 
them. 

- 

The levels are monitored. If danger arises, messages are to be read out. 

- 

The color mixing plant can only be operated after a password was entered. 

- 

Panel TP177B is to communicate with the SIMATIC S7-300 controller by means of the MPI. 

 
 

On the programmer, process visualization is generated for the color mixing plant, using the 
configuring software WinCC flexible 2005 Advanced. The process values are represented by 
graphics and graphic objects. Default values can be transferred to the controller with operating 
elements. The operator panel and the machine or the process communicate by means of variables 
via the controller. The value of a variable is written to a memory area (address) in the controller.  
There, it is read by the operator panel.  
Process visualization is stored and after generation, it is transferred by the programming device to 
the operator panel TP177B. 

After the panel is powered up, the process can be monitored and the plant can be operated.
