8.9 Warning Output Function (Process Alarm)
8.9 Warning Output Function (Process Alarm)
Outputs an alarm when the digital output value enters a preset range.
(1) Process alarm notification
When the digital output value moves above the process alarm upper upper limit value, or below the process alarm
lower lower limit value, thus entering the alarm output range, alarm notifications are made by Warning output flag
(Process alarm) (Un\G50), Warning output signal (X8) and the ALM LED turning ON.
In addition, alarm code 10  gets stored in Latest error code (Un\G19).
The alarm code that is stored is shown below:
(2) Operation of the Warning output function (Process alarm)
After the alarm is output, once the digital output value returns within the setting range, below the process alarm
upper lower limit value and above the process alarm lower upper limit value, a "0" (zero) is stored in the bit
position corresponding to the channel number for Warning output flag (Process alarm) (Un\G50).
Once all channels are within the setting range, Warning output signal (X8) and the ALM LED turn OFF.
