F13_ICWT

IC卡扩展内存写入

从s1_Start指定的地址读取由s2_Number指定字数的数据，并写入d_Start指定的IC卡中的扩展内存区。

参数

输入

s1_Start (WORD, INT, UINT): 源数据，起始16位区域
s2_Number(DWORD, DINT, UDINT, DATE, TOD, DT): 要读取后再写入IC卡的字数
d_Start(DWORD, DINT, UDINT, DATE, TOD, DT): IC卡扩展内存的目标区域

示例

POU头

所有用于编程此函数的输入和输出变量已在POU头中声明。所有编程语言使用相同的POU头。

	VAR 
		Var_Real: REAL:=0.0;
		Write_To_ICCard: BOOL:=FALSE;
		Read_From_ICCard: BOOL:=FALSE;
		ICCardStartAdr: DINT:=0;
	END_VAR
