Operands N: Bit number
The bit number must be between 0000 and 000F hexadecimal or between
&0000 and &0015 decimal. Only the rightmost bit (0 to F hexadecimal) of the
contents of the word is valid when a word address is specified.
Operand Specifications
Description LD TST(350), AND TST(350), and OR TST(350) can be 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. Unlike LD, AND, and
OR, bits in the DM area can be used as operands in TST(350).
LD TSTN(351), AND TSTN(351), and OR TSTN(351) can be 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.
Unlike LD NOT, AND NOT, and OR NOT, bits in the DM area can be used as
operands in TSTN(351).
