Hello,

I'm trying to use EPICS to run Kohzu SC-400 controller with soft IOC on

a Linux PC with GPIB card. At this stage I built EPICS and SynApps with

Linux GPIB package and can successfully talk to the controller via

asynRecord. Ideally I'd like to make it work with Ron Sluiter's Kohzu

SC-800 (same set of commands as SC-400) driver support, however I keep

getting the following error:

Illegal field value PV: kohzu:m1 motor_init_record_com(): card does not

exist!

My guess is that EPICS is looking for a VME card since VME_IO is listed

as address type in devKOhzuMotor.dbd file and can't find it for obvious

reason. I'm just starting building EPICS applications, so hopefully

there's an obvious solution that I can't see at the moment. Below is my

IOC startup file:

# Linux startup script
< envPaths
# save_restore.cmd needs the full path to the startup directory, which
# envPaths currently does not provide
epicsEnvSet(STARTUP,$(TOP)/iocBoot/$(IOC))
# Increase size of buffer for error logging from default 1256
errlogInit(20000)
# Specify largest array CA will transport
# Note for N sscanRecord data points, need (N+1)*8 bytes, else MEDM
# plot doesn't display
epicsEnvSet EPICS_CA_MAX_ARRAY_BYTES 64008
