The paper proposes the optimized evolution of the previous procedure to synchronize the PDAs to the node of the Distributed Measurement System (DMS) in order to physically bring the common sense of time to the stand alone node. The improvements concern with (i) the selection of the clock node as reference one, (ii) the contemporaneous synchronization of all the involved PDAs, and (iii) the compensation of the effects of the drift of the electronic components on the number of system cycle after whom the control of the MI must be executed. The improvements pointed out originate from the practical evaluation of the performance of the previous synchronization procedure. The improved procedure meets the advantages of the synchronization based on the IEEE std 1588. Experimental tests are shown to validate the synchronization procedure and to highlight the advantages.
