■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
■BOOL_TO_WORD(_E)
The program which converts bit type data input to (s) into word (unsigned)/16-bit string type data, and outputs the operation
result from (d).
• Function without EN/ENO (BOOL_TO_WORD)
[Structured ladder/FBD]
[ST]
g_word1 := BOOL_TO_WORD(g_bool1);
• Function with EN/ENO (BOOL_TO_WORD_E)
[Structured ladder/FBD]
[ST]
g_bool3 := BOOL_TO_WORD_E(g_bool1, g_bool2, g_word1);
■BOOL_TO_DWORD(_E)
The program which converts bit type data input to (s) into double word (unsigned)/32-bit string type data, and outputs the
operation result from (d).
• Function without EN/ENO (BOOL_TO_DWORD)
[Structured ladder/FBD]
[ST]
g_dword1 := BOOL_TO_DWORD(g_bool1);
ENO
TRUE
*1
FALSE
(d)
