Operation Error
An operation error occurs in the following cases.
The input value is other than '30
H' to '39H', '20H', '2DH', and '00H' of ASCII code.
(Error code: 4100)
The input value is outside the following ranges of ASCII code. (Error code: 4100)
STR_TO_INT(_E): '32768 to 32767'

(b) Function with EN/ENO (STR_TO_INT_E)
[Structured ladder]
[ST]
g_bool3 := STR_TO_INT_E (g_bool1, g_string1, g_int1);
(2) The program which converts string type data input to into double word (signed) type data,
and outputs the operation result from .
