Exam 3: Number Systems

When creating a tag in RSLogix 5000 software, what two attributes are assigned to the tag?

The SLC 500, MicroLogix, and PLC-5 are examples of 16-bit PLCs.

When programming instructions to add, subtract, multiply, divide, or compute, the expected size and format of the source tag or tags and answer tag must be taken into consideration.

Computers do not accept decimal numbers as inputs because they cannot convert from decimal to binary format.

One method of converting binary to hexadecimal is to start with the least significant bit (LSB) and break the binary number into groups of ____________________ bits.

What are the symbols used in the hexadecimal numbering system?

When programming or maintaining modern PLCs, you are likely to come across hexadecimal numbers in many different situations. What are two common instances of using hexadecimal numbers?

In the PLC world, a device on a network is referred to as a(n) ____________________.

The positional value of 2 in the decimal number 12,345 is 2 × 104.

In a 16-bit signed integer, the right-most bit represents the sign of the binary value.

The number of unique symbols used to represent numbers in a particular number system is indicated by the ____________________.

Traditional PLCs allocate a portion of the controller's physical memory segmented into data files for the storage of program-related information.

What is the base 2 value of AF1B316?

List three reasons why specific number system understanding is important.

ControlLogix has a basic memory allocation of ____________________ bits, or a double word.

A 16-bit word is made up of two bytes, an upper and a lower byte. Each byte is broken down into an upper and a lower ____________________.

What is the data range for a 16-bit signed integer?
