Allen-Bradley® Signed vs Unsigned Integer Work- Around

When a computer performs an unsigned integer arithmetic operation there are three possible problemswhich can occur: 1 if the result is too large to fit into the number of bits assigned to it an "overflow" is saidto have occurred For example if the result of an operation using 16 bit integers is largerthan 65535 an overflow results

One possible solution to the signed or unsigned integer issue is to use ControlLogix® to move the data from the integer data type into a double integer (32-bit integer) using ladder logic commands The logic for this approach is shown below

How do I convert an unsigned integer to a signed integer?

This technical note describes how to convert the GatewayPro’s 16-bit unsigned integer to a 16-bit signed integer using Allen-Bradley’s Control Logix®. One possible solution to the signed or unsigned integer issue is to use ControlLogix® to move the data from the integer data type into a double integer (32-bit integer) using ladder logic commands.

What is the difference between int and unsigned int?

As the names imply, int is a signed integer type, and unsigned int is an unsigned integer type. That means that int is able to represent negative values, and unsigned int can represent only non-negative values. The C language imposes some requirements on the ranges of these types.

What is a shortsigned integer type?

Shortsigned integer type. Capable of containing at least the [?32,767, +32,767] range. [a] 16 %hior %hd SHRT_MIN/ SHRT_MAX n/a unsigned short unsigned short int Shortunsigned integer type. Contains at least the [0, 65,535] range.

What is the difference between a long and an unsigned long?

Assuming 4 bytes, a long has the range of -2,147,483,648 to 2,147,483,647. An unsigned long has the range of 0 to 4,294,967,295. One other difference is with overflow. For a signed type, an overflow has unspecified behavior. But for an unsigned type, overflow is guaranteed to "wrap around." Wrap around is handled as overflow arithmetic.
