Review Object Mapping Chapter 5

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.
