re-establish a known operating point. The includes reinitializing the Tasks, Database, Communication
Ports, Sensor, and I/O and restoring the factory default configuration. This cold start does not include
any of the clearing options available in a Cold Start performed by using ROCLINK (see Section
2.8.2.2).
CAUTION
This type of reset restores the factory configuration defaults. Some user-entered
configuration parameters may be lost; therefore, try to back up any needed data
