|
81 |
|
82 Modbus extensions requires native Modbus RTU/TCP library to be installed nearby Beremiz. |
|
83 Following directory structure is expected: |
|
84 <Parent directory> |
|
85 "beremiz" |
|
86 "Modbus" |
|
87 |
|
88 If Modbus library is installed elsewhere, then place corresponding paths |
|
89 in CFLAGS/LDFLAGS in project settings. |
|
90 |
|
91 For GNU/Linux to install Modbus library in parent directory run following commands: |
|
92 $ hg clone https://bitbucket.org/mjsousa/modbus Modbus |
|
93 $ cd Modbus |
|
94 $ make |
|
95 |
|
96 After that Modbus extension is ready to be used in Beremiz projects.]]></xhtml:p> |
