(Application Functions)
Error
An operation error occurs in the following cases. The error flag M8067 turns ON, and D8067 stores the error
code.
1) When the value stored in a device specified in is outside the following range:
0, ±2
-126
≤ (Value of device specified in ) ≤ ±2
128
(Error code: K6706)
2) When the range of a device which will store the character string obtained by conversion (device specified
in ) exceeds the range of the corresponding device
(Error code: K6706)
3) When the conversion result exceeds the specified total number of digits
(Error code: K6706)
Program example
In this program, float (single precision) data stored in a device specified in is converted into string data,
and the data obtained by conversion is output to a device specified in .
1) Function without EN/ENO(REAL_TO_STR)
2) Function with EN/ENO(REAL_TO_STR_E)
