■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
■WORD_TO_STR(_E)
The program which converts word (unsigned)/16-bit string type data input to (s) into string type data, and outputs the
operation result data from (d).
• Function without EN/ENO (WORD_TO_STR)
[Structured ladder/FBD]
[ST]
g_string1 := WORD_TO_STR(g_word1);
• Function with EN/ENO (WORD_TO_STR_E)
[Structured ladder/FBD]
[ST]
g_bool3 := WORD_TO_STR_E(g_bool1, g_word1, g_string1);
■DWORD_TO_STR(_E)
The program which converts double word (unsigned)/32-bit string type data input to (s) into string type data, and outputs the
operation result data from (d).
• Function without EN/ENO (DWORD_TO_STR)
[Structured ladder/FBD]
[ST]
g_string1 := DWORD_TO_STR(g_dword1);
