This means that EPLAN allows the user to decide whether a project is error free or not and which priority a message (error, warning, or note) should have. Of course, it is possible to avoid even such errors. With the Prevent
errorscheck option, the above approach Would not be possible. But this is a freely adjustable setting.
EPLAN is an online system. All references or device data are kept constantly (i.e. online) up to date. The only limitations (if you want to call them this) relate to connection data. For performance reasons, these are only updated
as desired via a few specific actions, the rest is performed completely independently by EPLAN.
