I/O Power Monitor
The I/O power supply input can be monitored to confirm if it is normal. If an
I/O terminal on the NE1A-series Controller is set to any setting other than
Not
Used
and the normal power supply voltage is not input, the following items will
be displayed on the 7-segment display:
• Power supply for input not input normally: P4
• Power supply for output not input normally: P5
I/O power supply status can also be monitored in the General Status in
DeviceNet I/O communications.
5-1-3
Contact Operation Counter
Overview
In NE1A-series Controllers with unit version 1.0 or later, this function counts
the number of OFF
→
ON operations at a local input, test output, or local out-
put and stores the count internally in non-volatile memory.
• Count range: 0 to 4,294,967,295 operations (stored as 00000000 to
FFFFFFFF Hex)
• Count units: Operations
• Resolution: Depends on the cycle time.
This information can be monitored using the Network Configurator or explicit
messaging.
Note
(1) The Contact Operation Counter function (Count) and Total ON Time Mon-
itor function (Time) cannot be used simultaneously on one bit. Select one
of these functions with the Maintenance Counter Mode Choice setting.
(2) When the Maintenance Counter Mode Choice setting is changed, the col-
lected data (operations count or total ON time) will be cleared.
(3) These functions do not operate when the I/O power supply is OFF.
Setting the Contact Operations Alarm Threshold with the Network Configurator
The maintenance mode (Maintenance Counter Mode Choice) and alarm
threshold (Threshold Maintenance Counter) can be set for each local input,
test output, and local output terminal.
