■Operation result
• Function without EN/ENO
An operation is executed and the operation value is output from (d).
• Function with EN/ENO
The following table shows the executing conditions and operation results.
EN
TRUE (Operation execution)
FALSE (Operation stop)
*1 When FALSE is output from ENO, the data output from (d) is undefined. In this case, create a program so that the data output from (d) is
not used.
Operation error
• No operation error occurs.
Program example
■INT_TO_LREAL(_E)
The program which converts word (signed) type data input to (s) into double-precision real type data, and outputs the
operation result from (d).
• Function without EN/ENO (INT_TO_LREAL)
[Structured ladder/FBD]
[ST]
g_lreal1 := INT_TO_LREAL(g_int1);
• Function with EN/ENO
[Structured ladder/FBD]
[ST]
g_bool3 := INT_TO_LREAL_E(g_bool1, g_int1, g_lreal2);
■DINT_TO_LREAL(_E)
The program which converts double word (signed) type data input to (s) into double-precision real type data, and outputs the
operation result from (d).
• Function without EN/ENO (DINT_TO_LREAL)
[Structured ladder/FBD]
[ST]
g_lreal1 := DINT_TO_LREAL(g_dint1);
ENO
TRUE
*1
FALSE
(d)
