-> ones place -> thousands place in sequence. If the forward key (X13) is pressed, the switching
sequence is reversed. The cursor position is indicated by the LED indicator connected to the gating
pulse signal (Y004 to Y007).
3) Each time the increment key (X11) is pressed, the content pointed by the cursor is changed through
0 -> 1 -> 2 -> ……8 -> 9 -> 0 -> 1 in sequence. Each time the decrement key (X10) is pressed, the
content pointed by the cursor is changed through 0 -> 9 -> 8 -> 7 -> …… -> 1 -> 0 -> 9 in sequence.
The modied value takes effect immediately.
Usage:
If the user program has a short scan duration, use the constant scan mode, or start scanning at a xed
interval within a timing interrupt.
ABSD: Absolute cam control mode

Overview
When driving conditions are met, the ABSD instruction compares a data table from head address S1 with
the current value of a selected counter (S2) to control the ON/OFF states of K bit elements from head
address D.

Function
Multi-segment comparison is performed for cam control. The data table and counter used by comparison
are congured in absolute mode. This instruction is executed during the scan process of the main program.
The comparison result is affected by scan delay. In 32-bit operation, S1, S2, and D point to 32-bit variables,
and n is calculated based on 32-bit variable width.
