APPLICATION FUNCTIONS
DWORD_TO_INT(_E), DWORD_TO_DINT(_E)
DWORD_TO_INT(_E), DWORD_TO_DINT(_E)
Operation Error
No operation error occurs in the execution of the DWORD_TO_INT(_E) and
DWORD_TO_DINT(_E) functions.
Program Example
(1) The program which converts double word (unsigned)/32-bit string type data input to into
word (signed) type data, and outputs the operation result from .
(a) Function without EN/ENO (DWORD_TO_INT)
[Structured ladder]
[ST]
g_int1:= DWORD_TO_INT(g_dword1);
(b) Function with EN/ENO (DWORD_TO_INT_E)
[Structured ladder]
[ST]
g_bool3 := DWORD_TO_INT_E(g_bool1, g_dword1, g_int1);
(2) The program which converts double word (unsigned)/32-bit string type data input to into
double word (signed) type data, and outputs the operation result from .
(a) Function without EN/ENO (DWORD_TO_DINT)
[Structured ladder]
[ST]
g_dint1:= DWORD_TO_DINT(g_dword1);
