Experimental Physics and Industrial Control System
Ned and Larry,
Thank YOU that you return me on right way :) Ernest explained me
"level" yesterday. But I like to read myself.
There is "ASL: Access Security Level (Called access level in Req
Doc" and I decided Req is Record. As you know I tried to search in
Record's manual and looked into /src but information was closer ...
Also additional information about "ASL1=the default" to help me
understand *Record.dbd
Have a good day, Andrei.

Andrei,
The ASL is *not* a field in the record. It is an attribute defined for
each field in a record type in the xxxRecord.dbd file. For example
field(VAL,DBF_ENUM) {
prompt("Current Value")
promptgroup(GUI_INPUTS)
pp(TRUE)
asl(ASL0)
}
Fields that are routinely changed by operators get assigned ASL0, more
sensitive fields get assigned ASL1 (the default).
To change the ASL level of a field will require a new record type, i.e.
Andrei'sAIrecord
Andrei'sBIrecord
I have been in enough conversations about this to know that everyone has
there own opinion as to the effectiveness of this approach, so you won't
be saying anything new, Andrei.
