ABSTRACT:
A method is disclosed for packaging and collecting PM data generated in PM data modules having current and previous data banks as a source of PM data during a monitoring interval, including the steps of receiving a demarcation signal from a system timer indicating the expiration of the monitoring interval, sending a signal, responsive to the demarcation signal, to the PM data modules instructing each of the modules to swap data banks, reading the PM data located in the previous data bank representing the monitoring interval, optionally packaging the PM data into a single byte stream, sending an armed and ready message to a controller, receiving a request for bulk transfer of the PM data, transmitting the PM data in one bulk transfer to the controller, and resetting the system timer for a next monitoring interval.
