# Realistic workflow — configure the filter before querying
changelogFilter = system.mes.changelog.createFilter()
changelogFilter.setLimit(100)
changelogFilter.setDescending(True)
changelogFilter.setMESObjectTypeNames("Equipment")
events = system.mes.changelog.getChangeEvents(filter=changelogFilter)
