1.5 s
When the execution condition for the first IL(02) is OFF, TIM 00 will be reset
to 1.5 s, CNT 01 will not be changed, and 0102 will be turned OFF. When the
execution condition for the first IL(02) is ON and the execution condition for
the second IL(02) is OFF, TIM 00 will be executed according to the status of
0001, CNT 01 will not be changed, and 0102 will be turned OFF. When the
execution conditions for both the IL(02) are ON, the program will execute as
written.
3-7-11 END - END(01)
Ladder Symbol
END(01)
END(01) is required as the last instruction in any program. No instructions
written after END(01) will be executed. END(01) can be placed anywhere in
the program to execute all instructions up to that point, as is sometimes done
to debug a program, but it must be removed to execute the remainder of the
program.
If there is no END(01) in the program, no instructions will be executed and
the error message “NO END INST” will appear.
END(01) turns OFF the ER, CY, GR, EQ, and LE flags.
3-7-12 NO OPERATION - NOP(00)
NOP(00) is not generally required in programming and there is no ladder
symbol for it. When NOP(00) is found in a program, nothing is executed and
program execution moves to the next instruction. When memory is cleared
prior to programming, NOP(00) is written at all addresses. NOP(00) can be
input through the 00 function code.
There are no flags affected by NOP(00).
3-7-13 Timers and Counters
TIM and TIMM(20) are decrementing ON-delay timer instructions which re-
quire a TC number and a set value (SV). The TIM SV is input to the tenths of
a second; the TIMM(20) SV is input to the hundredths of a second.
