Omron SYSMAC CV Series - Shift N-Bits Left: Nasl(056)

168
Example When CIO 000000 is ON in the following example, the18 bits of data beginning
from bit 03 of CIO 0001 are shifted to the right, one at a time. A “0” is entered for
the beginning bit (CIO 000204) of the shift. The status of bit CIO 000103 is
shifted to CY.

C: Control word CIO, G, A, T, C, #, DM, DR, IR
When the execution condition is OFF, NASL(056) is not executed. When the ex-
ecution condition is ON, NASL(056) shifts the status of the 16 bits in the speci-
fied word to the left the specified number of bits.
The number of bits to shift is set in the two rightmost digits of the control word. If
the number is “0,” the data will not be shifted. The appropriate flags (see below)
will turn ON and OFF, however, according to data in the specified word.
