What is Channel Access? Channel Access is the Software Bus for EPICS
Application communication Channel Access

Records and Fields Records are common definitions of a collection
of fields. New record types are rarely developed at the CLS
In the simplest case, a Field is the minimum Channel Access data communicated
Device drivers are designed to process a record when a field updates (output) or when hardware values have been read (input)
