Explanations:
1. ANR instruction is used to reset an alarm.
2. When several alarm devices are ON, the alarm with smaller number will be reset.
3. This instruction is generally used in pulse execution mode (ANRP).

Program Example:
1. If X20 and X21 are ON at the same time for more than 2 sec, the alarm S912 will be ON. If
X20 or X21 is reset, alarm S912 will remain ON but T10 will be reset and present value is
cleared.
2. If X20 and X21 are ON less than 2 sec, the present value of T10 will be cleared.
3. When X3 goes from OFF → ON, activated alarms S912 will be reset.
4. When X3 goes from OFF → ON again, the alarm device with second lower number will be
reset.

Points to note:
Flags:
1. M1048 (indicating alarm status): When M1049 = ON, enabling any of the alarm S912~S1023
turns M1048 ON.
2. M1049 (Enabling alarm monitoring): When M1049 = ON, D1049 will automatically hold the
lowest alarm number in active alarms.
Application example of alarm device (production line):
X0 = Forward switch
X1 = Backward switch
X2 = Front position switch X3 = Back position switch
X4 = Alarm reset button
Y0 = Forward
Y1 = Backward
Y2 = Alarm indicator
S912 = Forward alarm S920 = Backward alarm
