数据类型：POINTER TO [...] name>: POINTER TO [...] Number: POINTER TO INT; i

| LWORD | POINTER TO [...] Address1: POINTER TO INT; i [...] 该确保指针的值在每个周期中都更新。 小心 不返回 Pointer-TO

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

: 输出不能是“REFERENCE TO [...] 定义 REFERENCE TO 作为输出参数。 错误修正 ： 不使用 REFERENCE TO

方式与类型变量相同 REFERENCE TO . 本节内容如下 : [...] 责用实现代码完全填写此函数。请参阅“POU 'CheckPointer [...] 没有，那么 CheckPointer 应该
