Dear All:
我想通过在OB1中调用FB5的背景数据块DB5、DB6，分别把DB2中夹有UDT3数据传到DB5、DB6，即：pot[0]的内容传给DB5;pot[1]的内容传给DB6。但是只能实现传给DB5，而不能实现传给DB6.。求助......

TYPE UDT3
STRUCT
data_type :STRUCT
Val_bool : BOOL ;
Val_byte : BYTE ;//1
Val_int : INT ;//2
Val_real : REAL ;//4
END_STRUCT ;
PIC_Struct_press : STRUCT
nY : INT ;
fTXWa : REAL ;
e_i : REAL ;
END_STRUCT ;
END_STRUCT
END_TYPE

DATA_BLOCK DB2
STRUCT
pot : ARRAY[0..1] OF UDT3 ;
END_STRUCT
BEGIN
pot[0].data_type.Val_bool := true ;
pot[0].data_type.Val_byte := b#16#10 ;
pot[0].data_type.Val_int := 50 ;
pot[0].data_type.Val_real := 100.00 ;

pot[1].data_type.Val_bool := false ;
pot[1].data_type.Val_byte := b#16#20 ;
pot[1].data_type.Val_int := 50 ;
pot[1].data_type.Val_real := 200.00 ;
END_DATA_BLOCK
