word (signed), double word (signed) type conversion
BOOL_TO_INT(_E), BOOL_TO_DINT(_E)
Operation Error
No operation error occurs in the execution of the BOOL_TO_INT(_E) and
BOOL_TO_DINT(_E) functions.
Program Example
(1) The program which converts bit type data input to into word (signed) type data, and
outputs the operation result from .
(a) Function without EN/ENO (BOOL_TO_INT)
[Structured ladder]
[ST]
g_int1 := BOOL_TO_INT(g_bool1);
(b) Function with EN/ENO (BOOL_TO_INT_E)
[Structured ladder]
[ST]
g_bool3 := BOOL_TO_INT_E(g_bool1, g_bool2, g_int1);
(2) The program which converts bit type data input to into double word (signed) type data,
and outputs the operation result from .
(a) Function without EN/ENO (BOOL_TO_DINT)
[Structured ladder]
[ST]
g_dint1 := BOOL_TO_DINT(g_bool1);
