Ver.9.0.1 data I/O feature was improved.
When an import or export command is used from a custom menu, scheduling parameter, or tool button to execute data I/O, only the data I/O object specified by the command is now connected.
Previously, all objects were connected if import, export, and synchronization were set to "Yes" in the data I/O settings even when they were not specified by the command. This improvement resolved the following problems.
Useless processing was inserted because connection was made to unnecessary data I/O objects.
An error in an unexecuted (unspecified) data I/O object caused interruptions.
