| For a 16-bit signed integer, SLC 500 counters can count within the range of:

A. -32,767 to +32,768

B. -32,765 to +32,764

C. -32,766 to +32,765

D. -32,768 to +32,767

Right Answer is: D

SOLUTION

  • 16-bit is a computer hardware device or software program capable of transferring 16 bits of data at a time.
  • The signed range of integer values that can be stored in 16-bits is: -2n-1 to 2n-1 – 1
  • i.e. -216-1 to 216-1 – 1 = -32,768 to +32,767

 

While the unsigned range is

0 to 2n – 1

0 to 216 – 1

0 to 65,536

NOTE:

For n-bit signed integer range

For n-bit unsigned integer range

[-2n-1 to 2n-1 - 1]

-32,768 to +32,767

[0 to 2n - 1]

0 to 65,536

 

  • SLC 500 series is a series of Allen-Bradley programmable logic controllers that are used for variety of applications.
  • SLC 500 series features ladder-logic with a structured text programming.
