Wd: Word
RLNC Wd
When the execution condition is OFF, RLNC(260) is not executed. When the ex-
ecution condition is ON, RLNC(260) shifts all Wd bits one bit to the left, shifting
the status of bit 15 of Wd into both bit 00 and CY.
CY
0
Content of *DM word is not BCD when set for BCD.
ER (A50003):
CY (A50004): Receives the status of bit 15 from Wd.
EQ (A50006): Content of Wd is 0 after execution.
N (A50008): Same status as bit 15 of Wd after execution.
When CIO 000000 is ON in the following example, the status of bit 15 of
CIO 0100 is shifted into bit 00 of CIO 0100 and into CR and the status of all bits
within CIO 0100 are shifted left one position.
