Operation Error
No operation error occurs in the execution of the BCD_TO_INT(_E) and BCD_TO_DINT(_E)
functions.
Program Example
(1) The program which converts BCD type data input to into word (signed) type data, and
outputs the operation result from .
(a) Function without EN/ENO (BCD_TO_INT)
[Structured ladder]
[ST]
g_int1 := BCD_TO_INT (g_word1);
(b) Function with EN/ENO (BCD_TO_INT_E)
[Structured ladder]
[ST]
g_bool3 := BCD_TO_INT_E (g_bool1, g_word1, g_int1);
(2) The program which converts BCD type data input to into double word (signed) type data,
and outputs the operation result from .
(a) Function without EN/ENO (BCD_TO_DINT)
[Structured ladder]
[ST]
g_dint1 := BCD_TO_DINT (g_word1);
