Modbus extensions requires native Modbus RTU/TCP library to be installed nearby Beremiz.
Following directory structure is expected:
<Parent directory>
  "beremiz"
  "Modbus"

If Modbus library is installed elsewhere, then place corresponding paths
in CFLAGS/LDFLAGS in project settings.

For GNU/Linux to install Modbus library in parent directory run following commands:
$ hg clone https://bitbucket.org/mjsousa/modbus Modbus
$ cd Modbus
$ make

After that Modbus extension is ready to be used in Beremiz projects.]]></xhtml:p>
