APPLICATION FUNCTIONS
WORD_TO_BOOL(_E), DWORD_TO_BOOL(_E)
WORD_TO_BOOL(_E), DWORD_TO_BOOL(_E)
Operation Error
No operation error occurs in the execution of the WORD_TO_BOOL(_E) and
DWORD_TO_BOOL(_E) functions.
Program Example
(1) The program which converts word (unsigned)/16-bit string type data input to into bit type
data, and outputs the operation result from .
(a) Function without EN/ENO (WORD_TO_BOOL)
[Structured ladder]
[ST]
g_bool1:= WORD_TO_BOOL(g_word1);
(b) Function with EN/ENO (WORD_TO_BOOL_E)
[Structured ladder]
[ST]
g_bool3 := WORD_TO_BOOL_E(g_bool1, g_word1, g_bool2);
(2) The program which converts double word (unsigned)/32-bit string type data input to into
bit type data, and outputs the operation result from .
(a) Function without EN/ENO (DWORD_TO_BOOL)
[Structured ladder]
[ST]
g_bool1:= DWORD_TO_BOOL(g_dword1);
