S7 Graph / PDiag / ProAgent Workshop (ST-7GRAPH)

  • This course is aimed at personnel who require a greater understanding of how programs are implemented using the S7GRAPH software using Step7 V5.5, how to use editing tools for making changes and diagnostic features for fault finding. The PDIAG aspect of the course is to demonstrate how further diagnosis can be added onto HMI's in order to make fault finding easier for maintenance personnel.


  • On completion of the course the participant will be able to:-
  • Understand the justification for using the GRAPH language
  • Understand the relationship of sequence operated applications
  • Create a basic sequencing program
  • Monitor and diagnose faults within a sequencer
  • Configure diagnostic information for HMI applications
Type Face-to-face training
Duration 3 days
