2.2.2 NION-16C48M LED Descriptions
The NION-16C48M is configured and operated over the network from a IFI Workstation using the
NION-16C48M Plug-In configuration utility. The only operation information involving the
hardware is the LEDs that display the status of various parts of the NION. The LEDs (as shown
below), operate in the following fashion:
• NION Status LED - The NION status LED shows the status of the NION itself. If the LED
is flashing slowly, the NION is operating normally. If the LED is on solid, then the NION is
not functioning properly.
• Network Status LED - The Network status LED shows the status of the neuron chip that
interfaces the NION to the Echelon network. If this LED is flashing, then the neuron chip is
operating properly. If it is unlit, then the neuron chip is not operating, or not bound to the
network.
• Network Packet LED - The Network Packet LED indicates when information is sent or
received over the network. This LED will flash for activity in this manner.
• Service LED - The Service LED indicates the binding status of the NION. If this LED is
flashing, the NION is unbound. If this LED is lit, that indicates that the neuron chip is not
running or has reached an unrecoverable error. When bound, the LED is unlit.
• Input LEDs - Input LEDs indicate the current status of each input. Each LED will display
the following patterns for each device status:
Point Disable - The LED will flash once every seven seconds.
Point Disarm/Override with Input Active or Input Normal - The LED will flash three
times in rapid succession once every three seconds.
Point Arm/Disarm/Override with Wire Open - The LED will flash rapidly (about 20 times
a second) continuously.
Point Arm/Disarm/Override with Wire Short - The LED will flash slowly (about once a
second) continuously.
Point Armed with Input Active - The LED remains in the ON state continuously.
Point Armed with Input Normal - The LED remains in the OFF state continuously.
Each time the node is reset, all the LEDs will cycle once to test operation.
• Output LEDs - Output LEDs indicate the status of each relay output. If an Output LED is
off, then the associated output is not activated. If the LED is On, then the output is
activated.
• Serial Communications Activity LED - This LED flashes when information is transmitted
via the EIA-232 serial interface (not used for this application).
