IOC configuration

IOC startup directory

Instructions for EPICS base release 3.15 or later.

st.cmd

Add these lines to the IOC's st.cmd file before the call to iocInit:

# assume the IOC prefix has been set
epicsEnvSet("PREFIX", "xxx:")

# assume that IP stream protocols will be found
epicsEnvSet("STREAM_PROTOCOL_PATH", "$(IP)/ipApp/Db")

# Oxford CryoStream 800 cooler
epicsEnvSet("CS800_IP_ADDR", "10.0.0.173")
epicsEnvSet("STATUS_ADDR", "$(CS800_IP_ADDR):30304:30304 UDP")
epicsEnvSet("COMMAND_ADDR", "$(CS800_IP_ADDR):30305 UDP")
iocshLoad("$(IP)ipApp/Db/Oxford_CS800.iocsh", "PREFIX=$(PREFIX),INSTANCE=CS")

auto_settings.req

By convention to enable automatic discovery of autosave requests, the autosave request file is in the same directory with the PV database file. Both files share the same filename, up to the final part of the name (_settings.req and .db, respectively).

Thus, no additional configuration is needed here.
