(2) The size of function block input variables and output variables must
match the size of program symbols (global and local), as shown in the fol-
lowing table.
Size Function block variable data
1 bit BOOL
16 bits INT, UINT, WORD
32 bits DINT, UDINT, REAL, DWORD
64 bits LINT, ULINT, LREAL, LWORD
More than 1 Non-boolean

Note The program symbol NUMBER can be set only in the input param-
eters. The value that is input must be within the size range for the
function block variable data type.
The user can call an instance from any location. The instance will be executed
when the input to EN is ON.

In this case, the input to EN is bit 0.0 at the left of the diagram.
• When the input to EN is ON, the instance is executed and
the execution results are reflected in bit 1.0 and word D10.
• When the input to EN is OFF, the instance is not executed,
bit 1.0 is turned OFF, and the content of D10 is not changed.
