6.4 Data Transfer Instructions
6.4.7 Identical 16-bit data block transfers (FMOV(P))
(4) Selection whether to check a device range
Whether to check a device range during execution of the FMOV instruction can be selected
with the device range check inhibit flag (SM237) (only when the conditions for subset
processing are established).
While SM237 is ON, whether to + (n) - 1 is within the device range or not is not
checked.
For details of SM237, refer to Appendix 3 SPECIAL RELAY LIST.
SM237 can be used only for the Universal model QCPU whose first 5 digits of
serial number is 10012 or later.
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.
• The device range of n points from or exceeds the corresponding device range.
(Error code: 4101)
Program Example
(1) The following program outputs the lower 4 bits of D0 when XA goes ON to Y10 to Y23 in
4-bit units.
