Automation of Sequential Processes with GRAPH in the TIA Portal for S7-1500

  • Entry
  • Associated product(s)
Many applications in the area of manufacturing and process technology have sequential structures. Do you have sequential processes that must executed in sequential processing steps? Through use of sequence cascades with GRAPH your automation solution is considerably facilitated.

The focus for use of GRAPH is on the implementation phase. The characteristic features of GRAPH can also be used optimally during the operating and maintenance phase.

GRAPH is a graphic programming language for creating sequence controls. Within a GRAPH function block you program your program in the form of sequence cascades; whereby sequential processes can be quickly program in a clearly organized manner.
 



Advantages
Using GRAPH offers the following advantages:

  • Minimal programming effort and greater clarity through graphic programming.
  • Excellent legibility for maintenance personnel.
  • Less time in the commissioning phase thanks to the graphical programming interface.
  • Minimal implementation effort because there are few possibilities for errors when generating code.
  • High availability of the machine through process diagnostics functions (interlock and supervision).
  • Fast error detection through PLC code display and criteria analysis on the HMI.
