Corrective action
• As the error dialog box appears, identify
the location, stop using it for another
item, and then delete the item.
• An item used for another item is unable
to be deleted.
• Because a unique name must be used
for [Server service name] and [Device tag
name], use a different name.
• Clear the [High-speed sampling]
checkbox in the [Device tag settings].
• Registration of [High-speed sampling] is
limited to one tag only.
• Delete the component setting with
selection of any other than the first item,
or change the setting so that the first item
will be used for it.
• If [High-speed sampling] is selected, only
the first item in [Access target CPU
settings] (Control CPU) can be selected
for the tag component.
• Reduce the number of device points in
the tag setting to 96 or less.
• When [High-speed sampling] is selected,
set tag component devices within the
total of 96 points.
• Stop using the tag for the setting item by
which data are written to the tag, before
changing the setting.
• If the tag is used for a setting item by
which data are written to the tag, clearing
the [Prohibit data writing] box is not
allowed.
Corrective action

• Set the tag to data-write-enabled.
