How many bytes make up a 16-bit word in a PLC?

A 16-bit word in a PLC is made up of two bytes because one byte equals 8 bits. Therefore, when you have a 16-bit word, you can calculate the number of bytes by dividing the total number of bits by the number of bits per byte. In this case, 16 bits divided by 8 bits per byte equals 2 bytes. This is a fundamental concept in digital data representation, where the size of data formats is often measured in bits, bytes, kilobytes, etc. Understanding this helps when working with PLCs, especially when dealing with data structures, memory allocation, and communication protocols, ensuring that data is interpreted and processed correctly.
