Autosave settings

We try to enclose most possible autosave configuration within autosave.iocsh.

Preparation of DB

Each record in database file that needs to have values saved by autosave must have the one of following info tags. Such as

 info(autosaveFields, "PREC SCAN DESC OUT")
 info(autosaveFields_pass0, "VAL")
 info(autosaveFields_pass1, "VAL")

Each info tag should be matched with what one would like to use such as

• autosaveFields : before and after record initialization

  • settings.sav : in $(AS_TOP)/$(IOCNAME)/save
  • settings.req : in $(AS_TOP)/$(IOCNAME)/req

• autosaveFields_pass0 : before record initialization

  • values_pass0.sav : in $(AS_TOP)/$(IOCNAME)/save
  • values_pass0.req : in $(AS_TOP)/$(IOCNAME)/req

• autosaveFields_pass1: after record initialization (Most autosave values can be restored at Pass 0 and Pass 1 using the autosaveFields info tag.)

  • values_pass1.sav : in $(AS_TOP)/$(IOCNAME)/save
  • values_pass1.req : in $(AS_TOP)/$(IOCNAME)/req

Please look at the example in Autosave DB example.

How to enable it within e3

require autosave,5.9.0

epicsEnvSet("TOP", "$(E3_CMD_TOP)/..")
epicsEnvSet("IOCNAME", "as_test")

iocshLoad("$(autosave_DIR)/autosave.iocsh", "AS_TOP=$(TOP),IOCNAME=$(IOCNAME)")
