Manual Function Block Matching

The

Intelligent Update Manager

identifies function blocks using the names of the variables wired to their inputs. When the inputs match, the

Intelligent Update Manager

seamlessly transfers the values of local variables inside the function block to the new version of the application.

The

Intelligent Update Manager

is unable to match inputs wired from other blocks or corner connections since these wires are assigned temporary names possibly changing at each compilation. When the manager identifies instances of unmatched function blocks, the

Match Function Blocks

dialog box displays showing these instances.

Use the

Match Function Blocks

dialog box to manually match the snapshot version of the function block with the modified version. The leftmost column displays the program and its function blocks needing matching. Select the function block to match in this first column. Use the

Previous

and

Next

buttons to scroll between the different programs with function blocks that need matching.

The

Target

column (second column) displays the Target version function block while the third column displays the calling parameters (inputs) of the Target function block. The

Workbench

column (fifth column) displays the potentially matching version of the function block while the fourth column displays the calling parameters of the Workbench function block. Match the blocks by selecting the equivalent instances in the

Target

and

Workbench

columns. The columns displaying the calling parameters help identify an equivalent match. Upon making a correct selection, click the

Match

button to inform the

Intelligent Update Manager

that these blocks are equivalent. A green check-mark displays beside the matched instances. You can also unmatch selections.

Exit manual function block matching. An online update is no longer possible after exiting the

Match Function Block

dialog box. After exiting manual function block matching, recompile the project.
