The command status, the second byte in the reply packet for the module specific
command, can return three different responses, SUCCESS, RUNNING and DEAD.
These responses echo the state of the module at the time the command is sent. The
conditions for each response are as follows:
SUCCESS will be sent back when all of the following conditions are met:
•
Command and HART Channel number are both valid.
