Timer:

Timer is mainly used to keep an output ON for a specific length of time.

It provides a preset delay to the control actions.

In a timer, the output will be energized when the preset value becomes equal to the accumulated value.

Three different types of timers include a Delay-OFF, a Delay-ON, and a Delay-ON-Retentive timer.

Timer OFF Delay (TOF):

TOF refers to an off-delay timer.

TOF counts the time-based intervals as soon as the instruction becomes false.

Here, the output changes its state from high to low when the timer provides some time delay (instruction goes from ON to OFF state).

Explanation of Solution

b.

Given:

Consider the given conditions,

Input = True

EN = 1

TT = 1

DN = 1

Explanation:

The input is true, so the timer immediately assigns the DN signal bits value as true.

Since the input is received with true condition, the EN signal bit will become true...

Explanation of Solution

c.

Given:

Consider the given conditions,

Input = True

EN = 1

TT = 0

DN = 1

Explanation:

The input is true, so the timer immediately assigns the DN signal bits value as true...

Explanation of Solution

d.

Given:

Consider the given conditions,

Input = False

EN = 0

TT = 1

DN = 1

Explanation:

The input is received from true to false condition, so the DN signal bit will be still in the active mode...

Explanation of Solution

e.

Given:

Consider the given conditions,

Input = False

EN = 0

TT = 0

DN = 0

Explanation:

The input is received from true to false condition, so the EN bit is assigned with “0”...
