Clock synchronization between a HMI operator panel and a SIMATIC PLC

Image
Depending on the required time synchronization and the used SIMATIC controller, this application shows the right solution. IntroductionIn order for components, such as, for example, HMI operator panels and SIMATIC controllers to work in a plant with identical time, one of the listed components has to be the timer for all other components.
The component acting as timer is called clock master. The time receiving components are clock slaves.
TaskThere are several HMI operator panels in a plant that exchange data with a SIMATIC controller.
The following tasks are to be implemented:
In the first job, a HMI operator panel is to be the timing component.
(HMI operator panel → SIMATIC controller) In the second job, a SIMATIC controller is to be the timer component.
(SIMATIC component → HMI operator panel)Solution
WinCC TIA Portal offers various solutions for the task described. The solutions depend on the
SIMATIC controller used and the required clock synchronization.
The application shows…

Printing with SIMATIC Comfort Panels

Image
Task
By means of a control panel, it should be possible to output data such as a screenshot, a shift report or a fault messages report via a printer or an alternative.
It should be possible to print, independent from the manufacturer and type of the printer.
Solution
To offer a solution as generally applicable as possible for printing data, new printer drivers were developed for SIMATIC Comfort Panels.
The "optional package printer driver" contains the following printer drivers:
PDF print (print as a PDF file) HTML print (print as an HTML file) PostScript print (print via any postscript-compatible printer) Brother QL-650TD (thermo printer). The following figure gives a schematic overview of the most important components of the solution:

Advantages
The "optional package printer driver" offers the following advantages for you.
You can print either in PDF or HTML file format. By means of an integrated PDF viewer or the Internet Explorer, the printouts can be displa…
