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
