This section describes precautions on mounting or removing 120-series I/O Modules
while the power is being supplied.

Hot Swapping
a) Mounting or removing an I/O and other Modules while the external power supply is
being supplied ON to the Power Supply Module will allow the CPU Module to con-
tinue working normally. This function is called hot swapping (removal/insertion under
power).
b) Hot swapping allows replacement of I/O Modules without stopping the operation of
CPU Module.
c) If a Module is hot swapped, it will take several scan cycles for the new Module to run
normal I/O and communications processing as follows.
(1) I/O and Special Purpose Modules
Module will start normal I/O processing several scan cycles after being
mounted to the slot.
To use hot swapping effectively, remember that some Modules cannot be mounted or
removed while power is being supplied. Also be sure to consider the impact on the
overall control system before removing a Module.
The following table shows the Modules which support hot swapping.
