• If shift trigger X1 turns ON when X2 is in the OFF
state, the contents of the internal relay WR3
(internal relays R30 to R3F), are shifted one bit to
the left.
• “1” is shifted in R30 if X0 is ON, and “0” is shifted
in R30 if X0 is OFF.
• If reset trigger X2 turns ON (leading edge), the
contents of WR3 are cleared (all bits in the WR3
become “0”).
