ABSTRACT:
In a drilling system of the type comprising a rotatable drilling string, a drilling string communication system and a drilling direction control device connected with the drilling string, a method is provided for issuing one or more commands to the drilling direction control device utilizing a changeable first parameter associated with the drilling string and a changeable second parameter associated with the drilling string. The method includes providing at least one first parameter state, providing at least one first parameter event relating to the first parameter state; providing at least one second parameter state, providing at least one second parameter event relating to the second parameter state and issuing at least one command to the drilling direction control device in response to providing at least one of the first parameter event, the second parameter event, the first parameter state and the second parameter state.
