In particular, the Fuel Reading Variable List is a set of specified channel values averaged between start and stop events from a designated collector task. A Fuel Reading is the time-averaging of various performance measurements to represent the steady-state performance of the engine. For averaged values, the program configures a list of channels and sends the list to the stat_child task.<\/p>\n<p>After data for a Variable List is available, various flow and performance computations are made. The results are written into PAM Datapoint and local Fuel Log files.<\/p>\n<p>datapoint is usually started in the Go Script, \/cell\/go.scp, as part of the normal CyFlex startup sequence. It runs perpetually, responding appropriately to external CyFlex events.<\/p>\n<p>Specification =&gt; \/cyflex\/datapoint\/datapoint2.spc<\/p>\n<\/dd>\n<\/dl>\n<h3>See Also:<\/h3>\n<dl>\n<dd>\n<p><a href=\"\/wp-content\/uploads\/PAM-Data-Collection-and-Transfer.pdf\">PAM Data Collection and Transfer<\/a><\/p>\n<\/dd>\n<\/dl>\n","protected":false},"excerpt":{"rendered":"<p>Purpose: Control the sequencing and reporting of various channel measurements.
