BIT TEST
OR TST
350
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.

BIT TEST
OR TSTN
351
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.
