RE: Modbus module duplicating definitions

Ø  Compiling only with modbus.dbd generated the same duplicate error.

 

Yes, that is expected because modbus.dbd includes base.dbd, asyn.dbd, etc.  The master branch of the Modbus module does not contain modbus.dbd, it was removed in January, 2021.

Hi, Mark!

Compiling only with modbus.dbd generated the same duplicate error. Compiling with only modbusSupport.dbd apparently solved the problem.

Thanks!

Hi Marco,

 

Your EquipmentInclude.dbd file appears to be including both modbus.dbd and modbusSupport.dbd.  You should only include modbusSupport.dbd, remove modbus.dbd.

Hello!

Im compiling an old IOC which uses modbus-R2-11, asyn-R4-33 and base R3.15.6 to talk to an equipment. The old IOC version didnt have a EquipmentInclude.dbd file in src, so i tried adding it.
Compiling the IOC will result, with or without the Include file, in:

perl -CSD /usr/local/epics-nfs/base/R3.15.6/bin/linux-x86_64/dbdExpand.pl   -I. -I.. -I../O.Common -I../../../dbd -I/usr/local/epics-nfs/base/R3.15.6/dbd -I/usr/local/epics-nfs/modules/R3.15.6/synApps/R6.0/support/asyn-R4-33//dbd -I/usr/local/epics-nfs/modules/R3.15.6/synApps/R6.0/support/stream-R2-7-7c//dbd -I/usr/local/epics-nfs/modules/R3.15.6/synApps/R6.0/support/modbus-R2-11/dbd -o Eurotherm.dbd base.dbd stream.dbd drvAsynSerialPort.dbd modbus.dbd modbusSupport.dbd

dbdExpand.pl: Duplicate definition of record type 'mbboDirect'

Context: recordtype(mbboDirect) in file '/usr/local/epics-nfs/modules/R3.15.6/synApps/R6.0/support/modbus-R2-11/dbd/modbus.dbd'

  while reading 'modbus.dbd' to create 'Eurotherm.dbd'

dbdExpand.pl: Exiting due to errors

Then if i create the include file and add

 

include "base.dbd"

include "asyn.dbd"

include "drvAsynIPPort.dbd"

include "drvAsynSerialPort.dbd"

include "stream.dbd"

include "modbus.dbd"

include "modbusSupport.dbd"

 

it will generate the same error. Removing only the lines about modbus from the Include file lets the IOC compile, but starting the st.cmd file will return me things like:
st.cmd line 34: Command modbusInterposeConfig not found

st.cmd line 47: Command drvModbusAsynConfigure not found.

Etc. So i figure if i want to use the module i need to find the duplicate definition and remove it? Does anyone have any suggestions or tips?

Thanks in advance and good morning,

Marco
