There is also an additional advantage in what Peter is suggesting.
If you distribute the values in the database it is easier and more
transparent how you distribute alarms, which can be very important when
maintaining your database.

There is no need to have the device support distributing the values.
It is simpler to do this via database processing

and have the other records extract the values for
themselves from the original input record.

Subject: record/device support general style question

My way so far is another: There is one AsynDriver-powered record

(stringin) which retrieves and holds the status string. That
value is read

by a longin record via dbGetField() in a standard device
support, which

extracts the information and distributes to all the other
relevant records

via dbPutField(). Thus these other records don't need any
device/record

support implementation themselves but are set remotely.
Unfortunately this

complicates handling the alarm/invalid states of these records.
So the question is:

Would it be better to have already my AsynDriver-powered record, which

reads the status bytes, distributing the values to the
different records

via dbPutField()?

Alternatively I like the idea of only one device support
implementation

for several records which is flexible using the INP field as a

parameter...

Any suggestions?
What could be more 'stylish'?
Thanks in advance,
Jens
