Using optional safe handling of new devices

If you enable the safe handling option for the Series A FIM through its configuration
form in Control Builder, the following actions are automatically initiated when you add a
new device to a loaded Fieldbus link.
Clears any existing VCRs configured in the device.
Clears any existing link schedule.
Clears the primary link master flag on the device.
Sets the link settings in the device to the current link settings of the segment.
If required, changes the device to a basic one and restarts the device.
Enabling and disabling safe handling
You enable and disable the safe handling option through the Safe Handling of New
Devices Enabled check box on the Main tab of the FIM Block's configuration form in
Control Builder. The default is selected or checked check box, which means safe
handling is enabled.
Safe handling and previously commissioned devices
The safe handling option does not apply when removing and adding a previously
commissioned device to the Fieldbus link. However, if you remove a commissioned
device from one link and add it to another link, the device is treated as an
uncommissioned device and the safe handling option applies. If this same device is later
moved back to its original link, it will appear as an uncommissioned device and will
require a reload.
Removing power during a safe handling operation
The safe handling operation can take up to 30 seconds to complete after adding a new
device to a link. If you remove a device while the safe handling operation is in progress,
it may have its configuration partially cleared.
