DINT to String (DTOS)
The DTOS instruction produces the ASCII representation of a value.
The DTOS instruction converts the Source to a string of ASCII characters and places the result in the Destination.

Major/Minor Faults
Type | Code | Cause | Recovery Method |
|---|---|---|---|
4 | 51 | The LEN value of the string tag is greater than the DATA size of the string tag. | Check that no instruction is writing to the LEN member of the string type tag. In the LEN value, enter the number of characters that the string contains. |
4 | 52 | The output string is larger than the destination. | Create a new string type that is large enough for the output string. Use the new string type as the data type for the destination. |
See Index through arrays for operand-related faults.
Execution

Condition/State | Action Taken |
|---|---|
Prescan | N/A |
Rung-condition-in is false | N/A |
Rung-condition-in is true | The instruction executes. |
Postscan | N/A |
Example
When temp_high is set, the DTOS instruction converts the value in msg_num to a string of ASCII characters and places the result in msg_num_ascii. Subsequent rungs insert or concatenate msg_num_ascii with other strings to produce a complete message for a display terminal.
