Experimental Physics and Industrial Control System
|
Thanks for your response..
If there is any way or any tool in order to make database
generation, i'll be glad to know.
The thing is that i can do IOC installation. I mean, I made the
database structure via VDCT and controlled it by using this path
"../../iocBoot/iocmyexample" (epics> dbpf ..) .
What I have done is, I used "dbpf,dbpr" commands to change and
look the values of PVs. However, i want the program to read the
data from the supported hardware and in somehow process them
(which is basicly to say,e.g take the data under the desirable
value).
The point that i was in trouble, I could not find how to
configurate the database with hardware (I have the driver of the
hardware). Another point is that let's say, i figure the
configuration out ; how can i allow the database to read the data
automatically ? Should i use any control loop to do that and where
should i do if it is like that ?
If i am not wrong, there is an extension called as "Sequencer"
which uses "State Notation Language". Does this allow me to
generate the database by using C language ? If it is like that,how
can i use it ?
Which tools should i use for whole project (or simple examples,e.g
reading data,processing them and monitoring on the screen) ?
Right now, i have these ones : MEDM, Alarm Handler, Probe, Strip
Tool, Sequencer(but i don't know how to use it,i am searching..).
In addition,i have these supports : SSCAN, Calc, Autosave (I
couldn't configurate them with database,e.g i couldn't use "snc"
command on the IOC application.) .
I am in trouble about making/configurating whole project's parts
together..
Thanks in advance,best regards..

I am new at EPICS. I am confused about using Visual DCT. I can easily
reading data and writing data from the terminal. However, i could not
make any condition loop inside the database and also could not
communicate the ports or hardware that are already supported by EPICS.
If there any resources,tutorials or videos about this topic, i will be
really pleasure to know.Because, i could not find any detailed document
on the Internet.
Visual DCT is one way to generate database files which is the simplest
one for newcomers to EPICS, but it's not the only way.
Unfortunately we don't have a video of my IOC Database Principles
lecture which is where this topic is covered best, although the slides
are available online so you can look through those — go through the IOC
Applications lectures at http://www.aps.anl.gov/epics/docs/APS2014.php
to learn about creating IOCs. The following lecture IOC Database
Practice also helps by giving examples of techniques commonly used.
There is also a discussion about database programming in the Database
Concepts chapter of the Record Reference manual
https://wiki-ext.aps.anl.gov/epics/index.php/RRM_3-14_Concepts
which may fill in a few more details that aren't on my slides.
If you have questions, ask them on this mailing list; there are many
people here who can help.
