Abstract
A method and system are disclosed for controlling a plurality of perforating gun assemblies arranged in a gun train and lowered into a wellbore. The perforating gun assemblies are connected to a top sub controller that is also lowered into the wellbore. The top sub controller includes a first communications module to communicate with an above-ground control panel via a wireline and a second communications module to communicate with a switch sub in each the plurality of perforating gun assemblies via a network bus. Each switch sub has a unique network address. During assembly, the control panel automatically detects the order of the perforating gun assemblies in the gun train based on polling each of the switch subs of the plurality of perforating gun assemblies using the respective unique network addresses.
