Zusammenfassung:	PURPOSE:To display the warning of a buzzer and a comment without separately connecting a buzzer or a display to the outside of an I/O unit by incorporating an instruction word operating the output equipment of a programming console as one usable instruction word that a user program can use. CONSTITUTION:A flag FUM is provided for the I/O number 5400 of a specific auxiliary relay area, and made usable in the user program as a protocol control display output relay. Simultaneously a flag FBZ is provided for the I/O number 5415 of the specific auxiliary relay area and made usable in the user program as a protocol control buzzer output relay. As any output condition holds, the buzzer 82 installed on a programming console is caused to ring or an LCD indicator 81 is caused to display comments composed of any characters.
