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