Reviewing and Modifying
Expressions If any objects in your PanelView 1000e or 1400e application contain
expressions, you need to review the order of precedence in each
expression. The order of precedence may be different between
PanelBuilder 1400e software and FactoryTalk View ME software.
The table compares the order of precedence in expressions between
PanelBuilder 1400e and FactoryTalk View ME software.
The conversion log does not indicate which objects contained
expressions with the “--check and reuse as needed--”” text. Refer to
Appendix A. Tag substitution provides a method of identifying if a
display contains expressions that require updates. The object explorer
section also describes how to highlight objects with expressions on
the display.
IMPORTANT
The text "--check and reuse as needed--" precedes all migrated
expressions. Remove this text from each expression and verify
the order of precedence.
