This Application Note describes how to recompile the FieldTalk Modbus Slave C++ Library / Windows Edition with Visual Studio 2005. The product is delivered with a precompiled static library which is ready to be used. Recompilation is only required if your project requires custom settings or modifications. Prerequisites • Visual Studio 2005 Standard or Professional • The Windows Edition of the FieldTalk package must be installed and unzipped on your development computer.
Compilation using Visual Studio IDE The FieldTalk package contains a folder structure similar to this: My Projects fieldtalk doc include src lib win win32 release samples Visual C++ 6.0 Visual Studio 2003 Visual Studio 2005
Directory containing the makefile Directory containing the library file libmbusslave.lib

Directory containing the Visual Studio 2005 project files to compile the library Open Visual Studio and load the mbusslave_win.sln solution file from the Visual Studio 2005 directory of the FieldTalk package. Select Rebuild Solution from the Build menu.
The compilation starts and the Output window will show a log similar to this: 1>------ Rebuild All started: Project: libmbusslave, Configuration: Release Win3 1>Deleting intermediate and output files for project 'libmbusslave', configurati 1>Compiling... 1>MbusTcpSlaveProtocol.cpp 1>MbusSlaveServer.cpp 1>MbusSerialSlaveProtocol.cpp 1>MbusRtuSlaveProtocol.cpp 1>MbusAsciiSlaveProtocol.cpp 1>hmtimer.cpp 1>hmserio.cpp 1>Generating Code... 1>Compiling... 1>hmhex.c 1>hmcrc16.c 1>BusProtocolErrors.c 1>Generating Code... 1>Creating library... 1>Build log was saved at "file://c:\prj\fieldtalk\cpp.backup\obj\win\Win32\Relea 1>libmbusslave - 0 error(s), 0 warning(s) ========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========
The rebuilt library libmbusslave.lib has been placed in the directory lib\win\win32\release, the library include files can be found in the directory include.
Changing the compiler settings Typically some of the following compiler settings may be adjusted depending on your project needs. The following list shows the most common adjustments. • The libraries' character set must match your project's character set. Unless you are targeting Windows 98, you should use Unicode as shown below:

• It is recommended to use the same runtime library settings for FieldTalk as you use for your main project. Adjust as shown below:
• For backward compatibility with Visual C++ 6.0 the library is compiled with the floating point option /QIFIST set. This setting should be removed with Visual Studio 2005, as it is now deprecated.

To remove, open the C/C++ Command Line property page and remove the /QIFIST entry as shown below.
Compilation using nmake Open a Visual Studio Command Prompt window from the start menu as shown below.
Change into the src subdirectory of your FieldTalk installation directory: cd c:\proconx\fieldtalk\src
Run nmake from the Visual Studio 2005 Command Prompt window: nmake
The compilation starts and the output will show a log similar to this: C:\proconx\fieldtalk\src>nmake Microsoft (R) Program Maintenance Utility Version 8.00.50727.42 Copyright (C) Microsoft Corporation.

Library successfully compiled.
The rebuilt library libmbusslave.lib has been placed in the directory lib\win\win32\release, the library include files can be found in the directory include.
Trouble shooting the Modbus communication using trace The library has a tracing feature which logs all communication events and raw data to standard output. To use this trace feature, the library needs to be recompiled with the TRACELOG definition defined. TRACELOG: TRACELOG: TRACELOG: TRACELOG: TRACELOG: TRACELOG: TRACELOG:
Open port: COM1 Parameters: 9600, 8, 1, Configuration: 1000, 0, Frame silence: 5 Read multiple registers Send(6): 01 03 00 63 00 Recv(5): 01 83 01 80 F0
0 0 1 100 0A
Raw data sent on the serial port Raw data received on the serial port In Visual Studio, trace can be enabled by defining the TRACELOG preprocessor definition from the C/C++ Preprocessor property pages as shown below:
Using nmake, TRACELOG can be defined by passing a tracelog parameter (all lower caps) to the makefile as follows:
