To 'swap' is to 'exchange'.
'Hot' means electrically live and powered.
The term "hot swappable" means that an I/O card can be
replaced while the PLC/PAC/controller rack/chassis is
powered and running.
The assumption is that the controller will recognize
or 'see' the replacement card and do whatever
initialization is required to bring the I/O card back on-
line.
An I/O card that is not 'hot-swappable' requires a cold
start, power-up, initialization sequence for the controller
to recognize the card.
