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.
Objectives
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

Prerequisites
The ability to use a MS Windows PC (W7), keyboard and mouse to include opening and closing programs, locating files, copy and paste objects /data (text, etc). Drag and drop files, objects/data (text, etc). Use of menus and multi-menus, manipulation of windows within a multi-window environment. Use of MS Windows Help.
