Sample program

When the execution condition CIO 0.00 is ON, the logical OR is taken of corresponding bits in CIO 21,

CIO 20 and CIO 31, CIO 30 and the results will be output to corresponding bits in D501 and D500.

ORW

ORW(035) takes the logical OR of data speci-

fied in I1 and I2 and outputs the result to R.

ORWL

ORWL(611) takes the logical OR of data

specified in I1 and I2 as double-word data and

outputs the result to R, R+1.
