• If (D) specifies data of a device with digit specification, the amount of data stored in the device specified by (D) will be
transferred. If K5Y0 is specified by (D), the lower 20 bits of the word device specified by (S) will be the object. If both (S)
and (D) specify data of a device with digit specification, the amount of data specified by (D) will be transferred regardless of
the number of digits.
• If the value specified by n is 0, the instruction will be not processed.
• Whether to check a device range during the execution of the DFMOV instruction can be set with SM237 (Device range
check inhibit flag). (Only when the conditions of the subset processing are established)
• In any of the following cases, an operation error occurs, the error flag (SM0) turns on, and an error code is stored into SD0.
• The following program stores the value data stored at Y0 to Y13(20 bits) into D10 to D17, when M0 is turned on.
