5.3.4. User-Defined Function Block
Why should we use function block?
There may be cases that using only ladders is too complex. At that time,
using a function block may be a good choice.
To know how to add a user-defined function block, we first explain how
HMIWorks uses these function blocks. Take “Assign” function block in the
“default” group for example.
How HMIWorks Uses Function Blocks
1.
Go to the installation path of the HMIWorks software. In the
sub-directory, “bin\FunctionBlock”, of that installation path, open the file
“Category.ini” to load the groups.
2.
If we choose the “default” group, then HMIWorks opens the
matching-name sub-directory and then loads from the matching-name “.ini”
file in that sub-directory. That is, the “default.ini” in the sub-directory
“default”.
