Subject:	does anyone use s7-nodave driver?

hi, all:

I am trying to use s7-nodave EPICS driver, the db file is like following:

record(ai,"$(id):ai")
{
field(DESC,"")
# field(SCAN, "I/O Intr")
field(DTYP,"s7nodave")
field(INP,"@t1plc MD4 int32")

}

when running st.cmd, it shows no errors:

#!../../bin/linux-x86/t1

< envPaths
epicsEnvSet("ARCH","linux-x86")
epicsEnvSet("IOC","ioct1")
epicsEnvSet("TOP","/home/geyang/t1App")
epicsEnvSet("EPICS_BASE","/usr/local/epics/r3.14.12.3/base")
epicsEnvSet("ASYN","/usr/local/epics/r3.14.12.3/modules/asyn4-13")
epicsEnvSet("S7NODAVE","/home/geyang/s7nodave-1.0.3")
cd /home/geyang/t1App

but I can't get the correct val from S7 plc. If I use the test program "testiso_tcp" coming with libnodave, I can exchange data with my S7-300 PLC. Can anyone give me some suggestions?

Thanks a lot for your help.

Best wishes
