Word objects addressed in the form of 16-bit words are stored in data memory and can contain an integer value from -32768 to 32767 (except for the Fast Counter function block which is from 0 to 65535).

• Immediate values
• Memory words (%MWi)
• Constant words (%KWi)
• I/O exchange words (%IWi, %QWi, %IWSi, %QWSi)
• System words (%SWi)
• Function blocks (configuration and/or runtime data)
