Subject: Re: SynApps sscan record: timestamp issue for BUSY DATA and EXSC fields; causing problem archiving with Phoebus Archive engine

Hello,
As suggested by Kay, I have added the following record to monitor the BUSY field.
record(bi, "ioc:Scan:busyVscan1")
{
  field(INP, "iocA:scan1.BUSY CP")
}

I am loading the scan configuration from the ConfigMenu option in the SynApps. The saveMenu.req file is modified to load records of interest.
In both the listing I am restarting the IOC, loading the config for scan and sequentially executing the scan twice.
It looks like the EXSC field is taking the timestamp of earlier execution. ie when it is going from 0 to 1.

Please find the camonitor listing with and without -tc option for the SMSG, EXSC, BUSY, DATA  and the above bi record. (I am wondering why does the camonitor not print VAL field for this record. does it have something to do with it being bi record??)

output of camonitor without -tc option

Hi Kuldeep,

This doesn't look like a normal scan to me.  BUSY should go to 1 promptly after EXSC is set to 1.  I would try monitoring SMSG to verify that the scan is behaving normally - not flailing with a disconnected positioner PV, for example.
