Var := DINT_TO_UDINT(di [...] Var :BYTE; udiVar : UDINT [...] _VAR liVar := ULINT_TO

Test:POINTER TO UDINT; udiTest:UDINT [...] INT then points to array [...] points to array

; udiLocal : UDINT [...] DWORD; a [...] DWORD; END_VAR ; 本节内容如下 :

Var := DWORD_TO_SINT(dw [...] Var:UINT; dwVar:DWORD; lw [...] Var := LINT_TO_SINT(li

操作一种类型的变量 POINTER TO 哪些不是 = （平等 [...] Temp : POINTER TO INT; i [...] Temp := piTemp * DWORD#5

_int : REFERENCE TO INT; ref_dw : REFERENCE TO DWORD; END [...] 类型变量 REFERENCE TO 理由：IEC 61131

器仅在乘法之后执行隐式转换： lint := TO_LINT(dint [...]  := TO_LINT(dint) * TO [...] : LWORD; udi : UDINT

Int : POINTER TO INT; dwAddress : DWORD; END_VAR dwAddress := dwAddress + DWORD

可能意外地导致意外访问。如果您指定一个 POINTER TO BYTE 到一个 POINTER TO DWORD ，那么

Val3: POINTER TO DWORD; hugo
