## ABS - Absolute Value

Absolute value |x| of a number x is itself, if x is positive or zero, but if x is negative, then its absolute value |x| is its negation –x, that is, the corresponding positive value. For example, |-1| = 1, but |2| = 2. The absolute value function strips a number of its sign.

#### Example

Equation: N7:120 = ABS (-10)

#### Ladder Logic Solution: #### Example

Equation: N7:121 = ABS (-25)

#### Ladder Logic Solution #### Note

• If the source is = 32768 (integer) this will generate a minor error fault. This error should be cleared to avoid a major error.

#### Example

Equation: F8:120 = ABS (-1.2345)

#### Ladder Logic Solution #### Note

• If the source is a floating point then no overflow error will occur.
