Channel Access

Available CA endpoints may be guessed from combining:

  1. XXX.substitutions - located next to st e.g. ADExample/iocs/simDetectorIOC/iocBoot/iocSimDetector/Overlay.substitutions
  2. corresponding template file - defined in the XXX.substitutions e.g. file "$(AREA_DETECTOR)/ADApp/Db/NDOverlayN.template"

Combing above 2 CA endpoint (one of): record(stringout, "$(P)$(R)Name") -> 13SIM1:Over1:1:Name
