Operation error
These functions consist of the following common instructions.
BCD_TO_INT(_E): BIN
BCD_TO_DINT(_E): BIN, WAND
• In any of the following cases, an operation error occurs, the error flag (SM0) is turned ON, and the corresponding error
code is stored to SD0.
Error Description
code
4100 Values other than 0 to 9 are specified for each digit of (s).
The error above can be suppressed by turning ON SM722.
However, the instruction is not executed regardless of whether SM722 is turned ON or OFF if the specified value is out of the
available range.
Program example
■BCD_TO_INT(_E)
The program which converts BCD type data input to (s) into word (signed) type data, and outputs the operation result from (d).
• Function without EN/ENO (BCD_TO_INT)
[Structured ladder/FBD]
[ST]
g_int1 := BCD_TO_INT(g_word1);
• Function with EN/ENO (BCD_TO_INT_E)
[Structured ladder/FBD]
[ST]
g_bool3 := BCD_TO_INT_E(g_bool1, g_word1, g_int1);
■BCD_TO_DINT(_E)
The program which converts BCD type data input to (s) into double word (signed) type data, and outputs the operation result
from (d).
• Function without EN/ENO (BCD_TO_DINT)
[Structured ladder/FBD]
[ST]
g_dint1 := BCD_TO_DINT(g_dword1);
