SDD is a tool exclusively used in ITER's CODAC Core System; most people here on EPICS Tech-Talk have never used it or don't even know what it is.
If you are a CODAC Core System user, please contact
[email protected] with your questions. The support team provided by ITER knows the system very well and will be able to help you. ITER is also offering a large number of introductory video presentations and 4-day training seminars on CODAC Core System - on-site in France as well as at the Domestic Agencies.
