controlled by the Option 01 are to be placed in when power is removed from the

VXI chassis containing the modules. <action_at_powerfail> must be OPEN or

SAME. If OPEN is specified, all latching relays are opened at powerfail. If

SAME is specified, all latching relays are left in their current state at powerfail.

shutdown and implementation of the PFAil OPEN option.
