Precautions
MOV(021) has an immediate refreshing variation (!MOV(021)). An external input bits can be specified
for S and external output bits can be specified for D. Input bits used for S will refreshed just before, and
output bits used for D will be refreshed just after execution unless the bits are allocated to a Group-2
High-density I/O Unit, High-density Special I/O Unit, or a Unit mounted in a SYSMAC BUS Remote I/O
Slave Rack.
When external input is specified for S, the value of S will be in-refreshed when the instruction is
executed and transferred to D. When external output is specified for D, the value of S will be transferred
to D and immediately out-refreshed when the instruction is executed. It is also possible to in-refresh S
and out-refresh D at the same time.
