Sequence Input Instructions Section 3-2
The operation of UP(521) and DOWN(522) depends on the execution condi-
tion for the instruction as well as the execution condition for the program sec-
tion when it is programmed in an interlocked program section, a jumped
program section, or a subroutine. Refer to 3-4-4 INTERLOCK and INTER-
LOCK CLEAR: IL(002) and ILC(003), 3-4-6 JUMP and JUMP END: JMP(004)
and JME(005), and 3-19 Interrupt Control Instructions for details.
Examples When CIO 0.00 goes from OFF to ON in the following example, CIO 100.00 is
turned ON for just one cycle.
When CIO 0.00 goes from ON to OFF in the following example, CIO 100.01 is
turned ON for just one cycle.
3-2-14 BIT TEST: TST(350) and TSTN(351)
Purpose 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.
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.
