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
-126
≤ (Value of device specified in
0, ±2
(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
d
(Error code: K6706)
3) When the conversion result exceeds the specified total number of digits
(Error code: K6706)
