功能块实例： PROGRAM PLC_PRG VAR <fb [...] _VAR ; PROGRAM PLC_PRG VAR [...] _VAR METHOD To

PLC_PRG VAR i : INT [...] TO INT; END_VAR I

器仅在乘法之后执行隐式转换： lint := TO_LINT(dint [...]  := TO_LINT(dint) * TO [...] PROGRAM PLC_PRG VAR d

示例： PROGRAM PLC_PRG VAR b [...] ; pt : POINTER TO FB

示例： PROGRAM PLC_PRG VAR i [...] TO INT; 本节内容如下 :
