Function
Takes a logical OR between logic blocks.

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 execution 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 program like LD, AND, and OR; the execu-
tion condition is ON when the specified bit in the speci-
fied 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 program like LD, AND, and OR; the execu-
tion condition is ON when the specified bit in the speci-
fied 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 program like LD, AND, and OR; the execu-
tion condition is ON when the specified bit in the speci-
fied 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.
