[With Q3A, Q4A, or Q4ARCPU]
• The annunciator number is displayed at the LED display device on the front of the CPU
module, and the "USER" LED goes ON.
• The annunciator numbers which are ON (F numbers) are stored in special registers (SD64 to
SD79).
• The value of SD63 is incremented by 1.
[With CPUs other than above]
• The "USER" LED goes ON.
• The annunciator numbers which are ON (F numbers) are stored in special registers (SD64 to
