Takes a logical AND between logic blocks.
LD
Logic block A

AND LD Serial connection between logic block A and
logic block B.
Takes a logical OR between logic blocks.
LD

LD
Logic block B
to
OR LD Parallel connection between logic block A
and logic block B.
Reverses the execution condition.
UP(521) turns ON the execution condition for one cycle when the exe-
cution condition goes from OFF to ON.
DOWN(522) turns ON the execution condition for one cycle when the
execution condition goes from ON to OFF.
LD TST(350), AND TST(350), and OR TST(350) are used in the pro-
gram like LD, AND, and OR; the execution condition is ON when the
specified bit in the specified word is ON and OFF when the bit is OFF.
LD TSTN(351), AND TSTN(351), and OR TSTN(351) are used in the
program like LD NOT, AND NOT, and OR NOT; the execution condition
is OFF when the specified bit in the specified word is ON and ON when
the bit is OFF.
LD TST(350), AND TST(350), and OR TST(350) are used in the pro-
gram like LD, AND, and OR; the execution condition is ON when the
specified bit in the specified word is ON and OFF when the bit is OFF.
LD TSTN(351), AND TSTN(351), and OR TSTN(351) are used in the
program like LD NOT, AND NOT, and OR NOT; the execution condition
is OFF when the specified bit in the specified word is ON and ON when
the bit is OFF.
