Removal and Insertion Under Power
You can insert and remove modules from the chassis while the power is applied. This allows
greater availability of the overall control system. There is not a disruption to any other
portion of the controlled process while the module is being removed or inserted.
ATTENTION:
Pulling the module from the chassis while power is applied causes the
message instructions carrying configuration, input, and output data to fail with an error.
Removal may also cause the module to lose any previous configuration.
