must designate the same type of device. Refer to
the function specifications table for each device in series for the
scope of device usage.
D1: Clear range’s initial device. D2: Clear range’s final device.
When the number of operand D1 > number of operand D2, only the operand
designated by D2 is cleared.
When X0 is ON, clears auxiliary relays M300–M399, changes them to OFF.
When X1 is ON, 16-bit clears counters C0–C79 (writes 0, and clears and changes
contact and coil to OFF).
When X10 is ON, clears timer T0–T127 (writes 0, and clears and changes contact
and coil to OFF).
When X3 is ON, clears the data in data registers D0–D100 (sets to 0).
Devices such as bit device Y, M and word device T, C, D can independently use
the clear command (RST).
