Explanation of example
If the 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 the X2 turns on, the contents of WR3 are reset to 0.
