1. A method of monitoring a condition of a machine in real time, the method comprising:
interfacing an edge device the machine;
requesting a handle from a controller of the machine;
querying the machine with an adapter of the edge device for a control data;
acquiring the control data from one or more sensors of the machine;
initiating an integrator when the acquired control data indicates a prespecified tool number;
initiating an action to the machine based upon a sum of load measurements from the control data provided by the integrator in response to the sum exceeding a predefined threshold value; and
repeating the steps of querying for the control data and acquiring the control data after a period of time at a high frequency defined by a sampling rate,
wherein during an initial connection period the adapter cycles through a set logic of repeating the steps of querying the machine and acquiring the control data to establish the sampling rate.
