Right-click on a
schedule item or use the toolbar to
add tags
to a selected schedule.
If the OPC server is connected you will be
able to browse the server and multiple-select tags to be added to the
schedule. Add multiple tags from the OPC server and a Source
Tag for each selection will be created with the server assigned name as it's
default name If the server is not connected or does not support tag browsing you will be able to define
individual tags manually with the tag properties form. You may not add
duplicate tags (with the same AccessName) to the same schedule.
If
your OPC server does not support browsing you may wish to import tags via a
CSV file. The file format is two comma delimited columns. The
first column is the server specific AccessName and the second column is the
tag's object name. You can simply use a single column of the AccessNames and
they will also be used as the default object Name.
Right-click or
double-click on a
tag in the grid or use the toolbar to access the tag's property sheet.

write forms to write values.
