可以由指针变量或 REFERENCE TO 多变的。 句法 [...] _pt: POINTER TO FB_B; var_ref: REFERENCE TO FB_C; END

_Init : BOOL VAR_INPUT b [...] to the copy code [...] _Init : BOOL VAR_INPUT nb

Output := TO_INT(TO_DINT(iInput [...] (input); .生成代码时，这会 [...] 须先复制输入值 input 到具有写访问权限的变量。 I

have to match [...] have to match [...] to data of type

Append : BOOL VAR_INPUT [...] Assign : BOOL VAR_INPUT [...] _VAR METHOD To

different to that in the [...] test_var_INT; // notation different to [...] different to that in the

Pointer : POINTER TO BYTE VAR_INPUT ptToTest : POINTER TO BYTE; i

任务可以填充一个布尔数组。 FUNCTION WriteTo [...] BOOL; END_VAR VAR_INPUT bToWrite : BOOL

Bounds : DINT VAR_INPUT index [...] to set a [...] or e.g. to halt on

_on_call'} FUNCTION_BLOCK fb VAR_INPUT [...] _on_call'} pInt : POINTER TO
