LREAL_TO_INT(_E), LREAL_TO_DINT(_E)
Operation Error
An operation error occurs in the following cases.
• The input value is -0 or outside the following range.
0, 2
• LREAL_TO_INT(_E): The input value is outside the range of -32768 to 32767.
• LREAL_TO_DINT(_E): The input value is outside the range of -2147483648 to
2147483647.
Program Example
(1) The program which converts double-precision real type data input to
type data, and outputs the operation result from
(a) Function without EN/ENO (LREAL_TO_INT)
[Structured ladder]
[ST]
(b) Function with EN/ENO (LREAL_TO_INT_E)
[Structured ladder]
[ST]
(2) The program which converts double-precision real type data input to
(signed) type data, and outputs the operation result from
(a) Function without EN/ENO (LREAL_TO_DINT)
[Structured ladder]
