Hints on Online Change
• Online Change is not possible after modifications in the Task or PLC Configuration,
after inserting a library and after performing 'Project' 'Clean all' (see below).
• If the download Information (file <projectname><targetidentifier>.ri), which had
been created at the last download (might have been an Online Change also) of the
project, has been deleted meanwhile (e.g. via command 'Project' 'Clean all', then
no Online Change will be possible further on, except for: The ri-file has been saved
at another location or has been renamed and therefore now is still available and
can be loaded explicitly by command 'Project' 'Load download information'.
Concerning this see also below 'Online Change for a project....'.
• Online Change does not cause a re-initialization of the variables, thus
modifications of the initialization values will not be regarded !
• Retain variables keep their values when an Online Change is done, they won't do
that at a re-download of the project (see below, 'Online' 'Download').
