Correction, scaler16m.db actually requires 5 macro arguments:

 

$(P)  The prefix

$(S)  The name for this scaler instance

$(FREQ)  The frequency of the clock input

$(DTYP)  The device type.

$(OUT)  The link specification for the hardware connection

scaler16m.db requires 2 macro arguments, $(P) and $(S).  You did not pass $(S).  You should change it to something like this:

 

dbLoadRecords("$(STD)/stdApp/Db/scaler16m.db", "P=$(PREFIX), S=scaler1")

Hi  all,

     I have a simple question about pv was all disconnected.

I run the xxx ioc, run the opi. But all pv in scaler16m.opi was disconnect.(the ioc did work well)

I typed dbl command, they were not listed, such as xxx:scaler1.S1.

I think the reason was missing some dbLoadRecord of std.
But still failed after I added the command "dbLoadRecords("$(STD)/stdApp/Db/scaler16m.db", "P=$(PREFIX)")" in st.cmd(common.iocsh)

The output of st.cmd:

Warning: '/usr/local/epics/synApps/support/std-R3-6-2/stdApp/Db/scaler16m.db' line 9 has undefined macros
Error: Bad character '$' in Record/Alias name "xxx:$(S,undefined)_calcEnable"
Error at or before ")" in file "/usr/local/epics/synApps/support/std-R3-6-2/stdApp/Db/scaler16m.db" line 9
Error: syntax error
dbLoadRecords: failed to load '/usr/local/epics/synApps/support/std-R3-6-2/stdApp/Db/scaler16m.db'

 

Could someone tell me what's wrong with me?

 

I use base 7.0.5,synapps 6.2, opi was control system studio.

 

Regards,
