Warm Boot Block
This block is sent from the ControlLogix processor to the module (output image)
when the module is required to perform a warm boot (software reset operation).
This block is commonly sent to the module any time configuration data
modifications are made in the controller tags data area. This will force the module
to read the new configuration information and to restart. The structure of the
control block is shown below:
