T. PROJECT COMMON DEFINITION
T.8. MULTIPLE PROJECTS CONNECTION BUILDER
The following describes how to operate and Monitor multiple projects that have
been connected.
T.8.1 ALLOW IDENTICAL TAG NAMES
If tag names between integrated projects are identical, a project ID will be added
to the tag name as a suffix in order to avoid identical tag names between
projects. Project ID can be defined in multiple projects connection builder of the
upper project, with two alphanumeric characters.
Figure: Multiple project connection builder
♦ Project ID Attachment Format
“Tag Name” + “@” + “Project ID” (a maximum of 16 characters)
(Example) FIC100@P1
Without adding a project ID suffix to the tag name, specify the operation to
be performed when the function block/element is called. In the Multiple
Project Connection Builder of the upper project, specify the operation by
choosing “Unique Tag Name Range” from the following two options:
• No identical tag names (unique for all projects)
If there are no duplicate tag names in any of the projects, select
“No” for “Allow identical tag names” in the Multiple Project
Connection Builder. This will search all projects. If the specified tag
name is unique for all the projects, the function block/element to
which the tag name is attached will be called. If there are duplicate
tag names, it is not predictable as to which of the function
blocks/elements having the same tag name will be called.
• Identical tag names (unique within the current project)
If tag names conflict between the integrated projects, specify “Yes”
for “Allow identical tag names” in the Multiple Project Connection
Builder. This will search all projects. If the specified tag name exists
