Experimental Physics and Industrial Control System
Hi everyone,
I have some problems about Channel Archiver and Alarm Handler. I have one ao record like this:
record(ao,"TC:PS:B1:AO1:current") {
field(SCAN,"Passive")
field(DTYP,"Soft Channel")
field(OUT,"TC:PS:B1:AI1:current")
field(DRVH,"250.0000")
field(DRVL,"-250.0000")
field(HOPR,"250.0000")
field(LOPR,"-250.0000")
field(HIHI,"200.0000")
field(LOLO,"-200.0000")
field(HIGH,"100.0000")
field(LOW,"-100.0000")
field(HHSV,"MAJOR")
field(LLSV,"MAJOR")
field(HSV,"MINOR")
field(LSV,"MINOR")
}
When I run Channel Archiver, it prompted the following messages:
11/30/2004 13:59:58.486441000, TC:PS:B1:AO1:current, IOC ppc3:8888 : Invalid/null time stamp
00:00:00 INVALID UDF
Why?
If I change the SCAN field to e.g. "1 second", it's ok. Can't we archive data from "Passive" records?
Also when I run Alarm Handler, it said:
TC:PS:B1:AO1:current <----------> <UDF,INVALID>,<INVALID>
Best wishes and regards,
Huang song
