3.3Task

In the case of the color mixing station, the program was modified using the programming device every time the mixing ratio had to be changed. Since these modifications are not only time-consuming but also risky if input is incorrect, the decision was made to add a TP700 Comfort Touch Panel to the color mixing station.

Using the panel, the following requirements are to be met:

-It should now be possible to operate the color mixing station via the panel as well.

-The fill levels of the tanks and of the reservoir are to be indicated as bars and also as numerical values.

-The movement of the mixer motor is to be represented graphically.

-The default quantities are to be entered using the panel.

-The minimum and maximum fill levels of the three tanks are to be displayed on separate tank screens.

-Switching between the operating modes is also to be performed using the panel, and the respective operating mode will be displayed on the panel.

-The finished mixtures are to be stored as recipes in the panel and need only be selected by the operator.

-The fill levels are monitored and alarms are to be generated in the event of danger.

-A password must be entered in order to operate the color mixing station.

-Communication of the TP700 Comfort Panel with SIMATIC S7-300 controller is to take place via the Ethernet interface.

3.4Configuration

The STEP 7 Professional V11 configuration software and WinCC Advanced V11 are used to create a process visualization for the color mixing station on the programming device. The process values are represented with screens and screen objects. Default values can be transferred to the controller using operator controls. Communication between the HMI panel and the machine or the process takes place

by means of tags via the controller. The value of a tag is written to a memory area (address) in the

controller, where it is read by the HMI panel.

The process visualization is saved and transferred from the programming device to the TP700 Comfort HMI panel after generation.

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