I/O Devices can now be configured to run in memory
An I/O Device running in memory
mode is created in memory and its values stored in memory at
Devices using memory mode are not
connected to any hardware, and write their values to a cache.
Memory mode is useful when you are configuring a system for the
first time, as you can design and test your system before
connecting a physical I/O Device.
Note: Memory mode replaces Memory I/O
Devices, which are no longer supported. Devices configured as
Memory I/O Devices will be converted to local variables during the
upgrade to v7.20.
