Operation error
Error code Description
(SD0)
3401H Data in the device specified by (s) is out of the range, 0 to 9999.
Precautions
When SM705 (Number of conversion digits selection) is on, the operation result is stored in (d) for the effective number of
digits. Therefore, when the BCDDA(P) instruction is executed successively and the operation result for each execution is
stored in the same device, a part of the previous operation result may not be overwritten by the succeeding result and can
remain in (d).
[Example] Executing the BCDDA(P) instruction when (s) is "9105H" and then executing another BCDDA(P) instruction when (s) is "0007H"
(1)
b15 b12 ∙∙∙ b11
(s) 9
(2)
b15 b12 ∙∙∙ b11
(s) 0
To avoid this, create a program to clear the entire data storage areas (d)+0 and (d)+1 before executing the BCDDA(P)
instruction.
(4)
b15 b12 ∙∙∙ b11
(s) 9
(6)
b15 b12 ∙∙∙ b11

(1) "9105" is converted into a string.

(3) A part of the previous conversion result remains
in (d)+1.

(4) "9105" is converted into a string.
(5) (d)+0 to (d)+1 are cleared.
(6) "7" is converted into a string.
