Operation error
These functions consist of the following common instructions.
When word (unsigned)/16-bit string type is specified for (s): BCDDA
When double word (unsigned)/32-bit string type is specified for (d): DBCDDA
• 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 When word (unsigned)/16-bit string type is specified for (s), (s) is outside the
range of 0 to 9999.
When double word (unsigned)/32-bit string type is specified for (s), (s) is
outside the range of 0 to 99999999.
4101 The device specified for (d) exceeds the corresponding device range.
Program example
■BCD_TO_STR(_E) (when word (unsigned)/16-bit string is specified for (s))
The program which converts word (unsigned)/16-bit string type data input to (s) into string type data, and outputs the
operation result from (d).
• Function without EN/ENO (BCD _TO_STR)
[Structured ladder/FBD]
[ST]
g_string1 := BCD_TO_STR(g_word1);
• Function with EN/ENO (BCD_TO_STR_E)
[Structured ladder/FBD]
[ST]
g_bool3 := BCD_TO_STR_E(g_bool1, g_word1, g_string1);
■BCD_TO_STR(_E) (when double word (unsigned)/32-bit string is specified for (s))
The program which converts double word (unsigned)/32-bit string type data input to (s) into string type data, and outputs the
operation result from (d).
• Function without EN/ENO (BCD _TO_STR)
[Structured ladder/FBD]
[ST]
g_string1 := BCD_TO_STR(g_dword1);
• Function with EN/ENO (BCD_TO_STR_E)
[Structured ladder/FBD]
[ST]
g_bool3 := BCD_TO_STR_E(g_bool1, g_dword1, g_string1);
