Hi,
Currently I am trying to make connection with epics and PLC, using s7nodave. I am following this guideline http://oss.aquenos.com/epics/s7nodave/docs/2.1.3/manual.html#recordreference
Below is what I have done but I am stuck.

1, Install EPICS base. Version is 3.15.5  
root@hy-VirtualBox:~/epics/base# ls
bin        db   documentation  include  LICENSE   README  startup
configure  dbd  html           lib      Makefile  src     templates

2, "makeBaseApp.pl -t example example"    " makeBaseApp.pl -i -t example example"      to build up mytest, the IOC application.
root@hy-VirtualBox:~/epics/mytest# ls
bin  configure  db  dbd  exampleApp  include  iocBoot  lib  Makefile

3, install asynDriver. Version is 4-33
Following this link, I add BPICS_BASE=/root/epics/base to asyn4-33/configure/RELEASE
https://epics.anl.gov/modules/soft/asyn/
root@hy-VirtualBox:~/epics/asyn4-33# ls
asyn           iocBoot      testApp                 testGpibApp
bin            lib          testArrayRingBufferApp  testGpibSerialApp
configure      LICENSE      testAsynPortClientApp   testIPServerApp
db             Makefile     testAsynPortDriverApp   testManagerApp
dbd            makeSupport  testBroadcastApp        testOutputCallbackApp
documentation  opi          testConnectApp          testOutputReadbackApp
html           README.md    testEpicsApp            testUsbtmcApp
include        templates    testErrorsApp

4,put boost_1_67_0 in a certain folder but not compile
root@hy-VirtualBox:~/epics/boost_1_67_0# ls
boost            boost.png      index.htm   libs             status
boost-build.jam  bootstrap.bat  index.html  LICENSE_1_0.txt  tools
boostcpp.jam     bootstrap.sh   INSTALL     more
boost.css        doc            Jamroot     rst.css

5, in s7nodave, configure/RELEASE file, add EPICS_BASE, ASYN, RELEASE_INCLUDES, and make s7nodabe
# If using the sequencer, point SNCSEQ at its top directory:
#SNCSEQ=$(EPICS_BASE)/../modules/soft/seq
SNCSEQ=/root/epics/seq
# The ASYN variable has to point to the asyn director.
#ASYN=/opt/epics/modules/synApps_5_5/support/asyn-4-13
ASYN=/root/epics/asyn4-33

# If the headers of the Boost library (http://www.boost.org/) are not installed
# in one of the default header locations (usually /usr/include and
# /usr/local/include) the includes path has to be added to RELEASE_INCLUDES.
# Only Boost headers are used, there is no need to compile the Boost library.
#RELEASE_INCLUDES+=-I/my/path/to/boost_1_47_0
RELEASE_INCLUDES+=-I/root/epics/boost_1_67_0
# EPICS_BASE usually appears last so other apps can override stuff:
#EPICS_BASE=/opt/epics/base-3.14.12
EPICS_BASE=/root/epics/base
# Set RULES here if you want to take build rules from somewhere
# other than EPICS_BASE:
#RULES=/path/to/epics/support/module/rules/x-y

# Allow the user to override settings locally.
-include $(TOP)/configure/RELEASE.local

6, in configure/RELEASE file of my own project, add "S/NODAVE=/opt/epics/modules/s7nodave"
# EPICS_BASE should appear last so earlier modules can override stuff:
EPICS_BASE=/root/epics/base

# Set RULES here if you want to use build rules from somewhere
# other than EPICS_BASE:
#RULES = $(MODULES)/build-rules

# These allow developers to override the RELEASE variable settings
# without having to modify the configure/RELEASE file itself.
-include $(TOP)/../RELEASE.local
-include $(TOP)/configure/RELEASE.local

ASYN=/root/epics/asyn4-33
S/NODAVE=/root/epics/s7nodave
S7NODAVE=/root/epics/s7nodave
SNCSEQ=/root/epics/seq

7, add "my_DBD += s7nodave.dbd"   "my_LIBS += s7nodave"  to /root/epics/mytest/exampleApp/src/Makefile
# Finally link IOC to the EPICS Base libraries
example_LIBS += $(EPICS_BASE_IOC_LIBS)

include $(TOP)/configure/RULES
#----------------------------------------
#  ADD EXTRA GNUMAKE RULES BELOW HERE
example_LIBS += asyn

#by hy
my_DBD += s7nodave.dbd
my_LIB += s7nodave

---------------------------------------------------------
After these configure, I run st.cmd, however, IOC shell still cannot recoginze the command s7nodaveConfigureIsoTcpPort
I notice the guideline mentioned that "However, you have to add asyn.dbd to the list of DBDs used by your project in order to enable these commands in the IOC shell. "
But how can I add asyn.dbd to IOC shell???? by dbLoadDatabase "/root/epics/asyn4-33/dbd/asyn.dbd" ????????????????
