Introduction
Bit shift instructions are used to shift the data string starting with source device S1 to the left or right by 1 to 15 bits as designated.
The data string can be 1 to 65535 bits. The result is set to the source device S1 and a carry (special internal relay M8003). The LSB
or MSB is filled with 0 or 1 as designated.
Bit shift and rotate instructions are used to shift the 16- or 32-bit data string in the designated source device S1 to the left or right
by the quantity of bits designated. The result is set to the source device S1 and a carry (special internal relay M8003).
The BCD left shift instruction shifts the BCD digits in two consecutive data registers to the left.
The word shift instruction is used to move 16-bit data to a destination data register and shifts down the data of subsequent data
registers as many as designated.
SFTL (Shift Left)
Applicable CPU Modules
Valid Devices
For the valid device address range, see pages 6-1 and 6-2 (Basic Vol.).
Internal relays M0 through M1277 can be designated as S1. Special internal relays cannot be designated as S1.
Since the SFTL instruction is executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction should be used as required.
CY
S1
When input is on, N_B-bit data string starting with source device S1 is shifted
to the left by the quantity of bits designated by device Bits.
The result is set to source device S1, and the last bit status shifted out is set to
a carry (special internal relay M8003). Zero or 1 designated by source device
S2 is set to the LSB.
