-
-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>
