UP
521
UP(521) turns ON the execution condition for one cycle when the execu-
tion condition goes from OFF to ON.
Required
CONDITION OFF
DOWN
522
DOWN(522) turns ON the execution condition for one cycle when the exe-

BIT TEST
LD TST
350
LD TST(350), AND TST(350), and OR TST(350) are used in the program
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.
Not required
BIT TEST
LD TSTN
351
LD TSTN(351), AND TSTN(351), and OR TSTN(351) are used in the pro-
gram 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.
