SET F,RST F

Function

(1) The annunciator designated by

*1

 • The annunciator numbers which are ON (F numbers) are stored in special registers 

(SD64 to SD79).

 • The value of SD63 is incremented by 1.

*1: When using the Basic model QCPU, the "ERR."LED goes ON.

(3) If the value of SD63 is 16 (which happens when 16 annunciators are already ON), even if a 

new annunciator is turned ON, its number will not be stored at SD64 to SD79.

(1) The annunciator designated by 

 is turned OFF when the execution command is turned ON.
