LD / LD NOT

The first condition that starts any logic block within

a ladder diagram corresponds to a LD or LD NOT

instruction.

LD - Normally Open contact, examine if On

LD NOT - Normally Close contact, examine if Off


8/23

OUT / OUT NOT

The OUT instruction is like a relay coil.

When there is a path of True instruction preceding

this on the ladder rung, it will also be True.When the instruction is True it is physically On.

We can think of this instruction as a normally open

output.

This instruction can be used for internal coils andexternal outputs.

The OUT NOT instruction is the reverse logic of

OUT instruction.


9/23

END (01)

The last instruction required to complete a

simple program is the END instruction.

When the CPU scan the program, it executes all

instructions up to the first END instructionbefore returning to the beginning of the program

and begin the execution again.

END


10/23

AND / AND NOT

When 2 or more conditions lie in series on the

same instruction line, the first one correspond to

a LD or LD NOT instruction, and the rest of the

conditions, to AND or AND NOT instructions.

AND - taking the logical AND of the executioncondition

AND NOT - taking the logical AND between its

execution condition and the inverse of its

operand bit.


11/23

OR / OR NOT

When 2 or more conditions lie on separateinstruction line running in parallel and joining

together, the first one correspond to a LD or LD

NOT instruction, and the rest of the conditions

correspond to OR or OR NOT instructions.

OR - taking the logical OR of the execution

condition.

OR NOT - taking the logical OR between its

execution condition and the inverse of its

operand bit.


12/23

AND LD

The AND LD instruction logically AND the

execution conditions produced by two logic blocks.

The OR LD instruction logically OR theexecution conditions produced by two logic

blocks.

Timer (TIM)

Timer is an instruction normally used for time delay. It can be ON delay or OFF delay.

The timer is based on a decrement method.

On-Delay-Timer after our sensor (input) turns on we

wait x-seconds before activating a solenoid valve(output).

Timer number 000 to 127 (Must not coincide withcounter)

Set value #0000 to #9999 (0 - 999.9 sec)

If the start input becomes OFF or the power is turnedOFF during operations before time up (current value#0000), the current value will be reset to the value set.

Counter (CNT)

CNT is a preset decrement counter.

It decrements one count every time an input signal

goes from OFF to ON.The counter must be programmed with a count input,

a reset input, a counter number and set value.

Set value can range from #0000 - #9999

Counter number 000 to 127 (Must not coincide withcounter)

Its current value will not be reset even if the PC power

supply is turned OFF. It will preserve the count until

then.
