This LN represents a task scheduler<br />FHBT Heart beat function of a controlling device<br />FXPS Functional priority status<br /><br />I can imagine such functions to be required in any number of mechanical/control processes, or even within a substation they could have their place. (GOOSE heartbeat function? Yes please.)<br /><br />And I expect a dam can leak at any number of places, no doubt, but why would they decide on making 2 LNs? Can't the different points not share a common LN and identify specifics through prefixes? I thought that was the convention.<br /><br />HLKG Leakage supervision.<br />HDLS Dam leakage supervision.<br /><br />Unless of course there is a major functional difference. I never built a dam.<br /><br />What's your opinion on this?<br /><br />Great blog by the way, best thing I found that keeps me up to date.Patricknoreply@blogger.com
