
In one Func Block file, you can write many functions, and they can be called by each
other.

Each Func Block file is independent, the function in other function block cannot be
called.

Func Block files can call C language library function in form of floating, arithmetic
like sin, cos, tan.

XC series PLC only support local variable, while XD/XL series PLC support both
local and global variable. This makes C language Block more flexible and convenient.

Recommended usage of global variables:
 ①
Use the soft component area instead of ordinary memory to store the data of global
variables.

The soft component space of PLC can be used as the global variable space, and the
security is guaranteed.
 ②
