Apparatus and methods for controlling and communicating with one or more tools in a downhole tool string including a tractor, an auxiliary tractor tool, a logging tool, a safety sub, a release mechanism, a unit containing sensors for monitoring downhole conditions, a setting tool, and a perforating gun. Control and communication are accomplished by sending signals from the surface to control switches in the control units on the tool, with redundant switches for safety, to state machines in the respective control units, each state machine returning a signal verifying switch status to the surface. The state machine need not return a signal including a unique identifier.

La présente invention concerne un appareil et des procédés permettant la commande et la communication avec un ou des outils dans un train d'outils de fond de trou comportant un tracteur, un outil tracteur auxiliaire, un outil de diagraphie, un raccord double femelle de sécurité, un mécanisme de déclenchement, une unité contenant des capteurs pour surveiller des conditions de fond de trou, un outil de réglage, et une pistolet de perforation. La commande et la communication sont effectuées par la transmission de signaux depuis la surface vers des commutateurs de commande dans les unités de commande sur l'outil, avec des commutateurs redondants pour la sécurité, à des machines d'états dans les unités de commande respectives, chaque machine d'états renvoyant un signal de vérification d'état de commutateurs vers la surface. La machine d'états n'a pas à renvoyer un signal comprenant un identifiant unique.
