32-bit command
－ － － －
Flag signal: None
Explanation
1. S: Start of source devices D: Start of destination devices n: Number of data to be
moved
2. The contents in n registers starting from the device designated by S will be moved to n
registers starting from the device designated by D. If n exceeds the actual number of
available source devices, only the devices that fall within the valid range will be used.
Example
1
When X10 = On, the contents in registers D0 ~ D3 will be moved to the 4 registers D20 ~ D23.

Assume the bit devices KnX, KnY, KnM and KnS are designated for moving, the number of
digits of S and D has to be the same, i.e. their n has to be the same.

To avoid coincidence of the device numbers to be moved designated by the two operands and
cause confusion, please be aware of the arrangement on the designated device numbers.
When S > D, the BMOV command is processed in the order as 1→2→3
