Hi,

I have an EPICS module called "modbus".  It uses asyn, and works on all supported EPICS architectures (Linux, Windows, vxWorks, etc.).  It supports TCP, serial RTU, and serial ASCII.  It has been tested on a variety of Modbus devices, but probably not WAGO.   Are you using a WAGO?  I looked at the NSLS WAGO support when I was writing my package, and I recall that there was something strange about the way WAGO treated addresses.  I didn't have a WAGO to test, so the driver may need a small addition to work on WAGO.

Here is the link:

Subject: uptodate version of modtcp?

Hi,
I saw the modtcp with WAGO support version for use on linux at NSLS.
Is this the latest version? Is there a version for the
current epics build system?
I downloaded this version and tried by fiddling with the Makefiles,
RELEASE and CONFIG files and ended up with compile errors:

/usr/bin/cc -c               -DUNIX  -Ddarwin   -ansi   -O3 -g   -Wall 
        -fno-common  -I. -I../O.Common -I. -I.. 
-I../../../include/os/Darwin -I../../../include 
-I/epics/base-3.14.10/../modules/sncseq-2.0.12/include 
-I/epics/base-3.14.10/include/os/Darwin -I/epics/base-3.14.10/include 
    -I/opt/local/include -I/sw/include   ../modtcpLib.c
