For machine procedure simulation, a method synchronizes a plurality of equipment procedures to a mobile device. The method receives a first equipment reference code for a first equipment instance at the mobile device. The method retrieves a first equipment procedure of the plurality of equipment procedures that is indexed to the first equipment reference code at the mobile device, the first equipment procedure including a machine simulation for the first equipment instance. The method receives a procedure step that includes a lockout decision indicating that the first equipment procedure requires a lockout of the first equipment instance. The procedure step is directed to the machine simulation. The method displays a simulated result for an operator simulation that shows a simulated operator interacting with the machine simulation in response to the procedure step lockout decision.
