Alarm Reference Channel Range
The alarm detection of multiple measurement channels and math channels can be
assigned to a single DO channel. When an alarm occurs on any of the assigned
channels, alarm output is activated. A range of consecutive channel numbers are
assigned. The range can span over units.
Note
• The alarm detection in the unit and the DO output is processed within the unit. Therefore, the
DO output continues even when the connection to the PC is cut off. If the alarm reference
channel range spans over multiple units or if the digital output module is not available in the
same unit, alarm detection is performed on the PC. In this case, alarm detection stops when
the connection is cut off. In addition, even when the connection is established, the alarm
detection interval may slow down.
• Alarms other than those on measurement channels do not function when not connected to
the PC.

• FAIL Output [Fail]

CPU is abnormal or if a power failure occurs, it is OFF.
