Many thanks for the information. I started off with MEDM for my control
system research work but found that it is not capable of applications
involving timing such as maintaining temperature profiles. Therefore, i
decided to work with et-wish.

MEDM is a thin client for EPICS. It does not provide any programming

capability to the user. If you wish for a "thick" client on which you

can do programming or scripting, there are many to choose from. For my

work, et_wish is no longer the modern thick client of first choice.

There are scripting capabilities in Control System Studio, for example.

 Or you could build your own tools from a C++/Qt framework such as

epicsQt or possibly build Python applications or some other higher level

application. The EPICS website has a list.

Often, you might consider adding into a client a capability which could

be used by other EPICS tools at your site. In this case, reconsider

adding that capability directly into an IOC to the benefit of _any_

client. The EPICS Application Developer's Guide is one reference for

you, after the Getting Started with EPICS training online

(http://www.aps.anl.gov/epics/docs/GSWE.php).

For timing involving maintenance of a temperature profile, I assume you

are interested in building a temperature controller in software?

Consider using the epid record in an IOC:
