isUpdatePending

Procedure that is published through data-targets to check if any updates are pending. This SBO version of the event turns around and RUNS it in the SDO to which the caller is mapped. If no pending updates are found, it publishes isUpdatePending to its targets.

Location: sbo.p

Parameters:

INPUT-OUTPUT plUpdate AS LOGICAL

Returns TRUE and stops the publication if update is pending.

Notes:

New is included as a pending update.
This routine is called from canNavigate, which is used by navigating objects to check whether they can trust an updateState(“UpdateComplete”) message.
