On the EPICS website under "Document -> Training" are these two links that will be helpful: 


http://www.aps.anl.gov/epics/docs/APS2014.php

http://www.aps.anl.gov/epics/docs/APS2015.php


Also on that page under "Downloads > Examples" is this link:


https://www.aps.anl.gov/epics/download/examples/index.php


If you watch the first few videos and try to deploy the Virtual Linac (a bundled EPICS control system example) you will have more specific questions ... and those are the types of questions that get the fastest response on this forum.


But just to give you some context and vocabulary as you watch the videos, to build a control system with EPICS you must configure, build and deploy one or more Input Output controllers (IOCs) which interface to your hardware (a plethora of interfaces are available). The IOC will read from and write to your hardware and channel access client programs running somewhere in the world (usually close to the IOC) will communicate to the IOC by passing information in the form of process variables (PVs).  Logic and automation can be implemented in the IOC or in the client ... whichever makes sense.

Subject: EPICS training information
 
Dear EPICS Tech-Talk,

We currently doing a research about EPICS, how to communicate with EPICS, EPICS topologies, and EPICS implementation in PLC IOC based systems.
As we are a group of students, and we are basically Electrical and Automation Engineers, the EPICS field is new for us, we have little knowledge about it.
We've tried to read through the website, still have few difficulties to go deeper in the content.
Our questions here are :
-How does 'EPICS' create a control system (the definition says so , "EPICS provides a number of tools for creating a control system"), meanwhile, another important part of another definition says "PS: When installing EPICS, does not create a control system"!
-Do we , as Automation Engineering students , need to learn the algorithm and the programming procedure if we will be maybe implementing EPICS with automated systems ? 
-EPICS is about collaboration between People, Labs, sites, is it mandatory or it can be used for educational individual use, if yes, what is the hardware needed for that.
-What are the software needed basically to use EPICS, as we will be using software like S7PLC or EtherCAT ? 

We appreciate having an answer soon as we are unfortunately under a time DDL.

Best Regards
