Forcing a Switch Between Primary and Back-up
Channels or Devices using FIX or iFIX
You can force the driver to toggle between the current and backup device when any
value is written to a Digital Output or Analog Output block. If the backup device is
only configured for use on the backup channel, the channel also switches. The driver
switches devices when you write a value to the block.
I/O address syntax: !SWITCH:NAME
where NAME is the name of the device you want to switch. You cannot switch only
from one channel to another.
