7.2. Manual function block matching (from release 3.5.1)

Function blocks are identified by the Online Update manager using the names of the variables wired to
their inputs. Where the inputs match, the online update manager automatically creates a recipe to
transfer the values of local variables inside the function block to the new version for bumpless transfer.
However, function blocks with inputs wired from other blocks or from corner connections cannot be
uniquely identified, because these wires are given temporary names which may change on each
compilation. These are reported as ‘DELETED’ and ‘NEW’ before release 3.5.1 and their local
variables reset to initial values.

At release 3.5.1, a manual matching window is presented on compilation. This presents all function
blocks which need the user to confirm a match.

This window shows each type of function block in each program. ‘Previous’ and ‘Next’ page through
each matchable group of function blocks. Each function block which needs manual matching is shown,
with its ‘instance number’ (e.g. 0065 above) and its calling parameters, traced back to named
variables. The instance numbers do not usually change, but they will change if any blocks are
copied/cut/pasted or if standard blocks are inserted (e.g. AND, OR etc.). More information is given in
Application Note AN-T80009.

Select the old function block on the list on the left for the existing running application, select its
equivalent in the new application, and click ‘Match’ to inform the update manager that these are the
same function block.

When all pre-existing blocks are matched, click ‘Save and Continue’.

If there are any function blocks which are not matched (either automatically or manually), the following
message appears:
