Data Movement Instructions

5-18-1 MOVE – MOV(21)

The following example shows instruction ASFT(17) used to shift words in an

11-word shift register created between DM 0100 and DM 0110 with C=#6000.

Non-zero data is shifted towards St (DM 0110).

Note The zeroes are shifted "upward" if C=4000, and the entire shift register is set

to zero if C=8000.

Ladder Symbols

DM 6144 to DM 6655 cannot be used for D.

When the execution condition is OFF, MOV(21) is not executed. When the

execution condition is ON, MOV(21) copies the content of S to D.

TIM/CNT numbers cannot be designated as D to change the PV of the timer

or counter. You can, however, easily change the PV of a timer or a counter by

using BSET(71).

Indirectly addressed EM/DM word is non-existent.

(Content of *EM/*DM word is not BCD, or the EM/DM area boundary

has been exceeded.)
