■DBCDDA
• Converts the individual digit numbers of hexadecimal notation of the BCD 8-digit data designated by (S) into ASCII codes,
and stores the results into the area starting from the device designated by (D).
For example, if the value 01234056 is designated by (S), the operation result would be stored following (D) in the following
manner:
• The BCD data designated by (S) can be in the range of from 0 to 99999999.
• The results of calculation stored in the device (D). All zeros on the left side of the "Number of significant digits" are zero-
suppressed.
• The data to be stored at the device designated by (D)+4 differs depending on the ON/OFF status of SM701 (number of
characters to output select signal).
Operation error
• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.
• When SM701 is OFF: Stores "0"
• When SM701 is ON: Does not change
