Sequence Input Instructions
Section 3-3
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 and EM areas 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 and EM areas can be
used as operands in TSTN(351).
Flags
Note In CS1 and CJ1 CPU Units, these are turned OFF.
In CS1-H, CJ1-H, CJ1M, and CS1D CPU Units, these Flags are left
unchanged.
Precautions TST(350) and TSTN(351) are intermediate instructions, i.e., they cannot be
used as right-hand instructions. Be sure to program a right-hand instruction
after TST(350) or TSTN(351).
Examples LD TST(350) and LD TSTN(351)
In the following example, CIO 000001 is turned ON when bit 3 of D00010 is
ON.
In the following example, CIO 000001 is turned ON when bit 3 of D00010 is
OFF.
AND TST(350) and AND TSTN(351)
In the following example, CIO 000001 is turned ON when CIO 000000 and bit
3 of D00010 are both ON.
