be entered, edited, stored and transferred to the PLC(Fig. 4.6.36). For all
of these activities, the operator is offered support in the form of symbols
and graphic images, as well as being able to delete, rename and
copy tool data records at will. The number of tool data records which
can be stored depends on the storage capacity of the industrial PC.
Failure diagnostics module
If a machine failure is signalled, the operator is able to access the failure
diagnostics module by pressing a softkey and have the possible error
causes and the relevant repair process with the necessary work stages
displayed on screen (Fig. 4.6.37). For each work stage, an instruction
text with a real image and, where necessary, also circuit diagrams,
hydraulic plans or technical drawings are displayed. The relevant section
of the illustration is highlighted by an icon.
For each error message, the operator is able to enter the date, the
name of the processing staff member and a commentary for the records.
