What is WORD in PLC Programming? WORD is a fundamental data type in PLC programming used to store 16 bits of data. Unlike an INT, which is a signed number, a WORD is an unsigned 16-bit value that can store numbers from: 0 to 65,535 A WORD is commonly used to store groups of digital signals, status information, communication data, and device registers. Because it contains 16 bits, a single WORD can represent the state of 16 digital inputs or outputs at the same time.
