GE IC697VAL318 Analog Output, Isolated, 8 channel
Module IndicatorsThe Ethernet Interface board indicators consist of four Light Emitting Diodes (LEDs):
MODULE OK
LAN ONLINE
SERIAL ACTIVE
STATUS
Refer to Figure 2 for the location of the LED indicators,
and Table 1 for a description of the indicators.
Table 1. Ethernet Interface (Type 2) LED Indicators
Indicator Status Description
MODULE OK ON This LED is ON if the Ethernet Interface has passed diagnostics and is operating properly.
OFF This LED is OFF if the module fails a diagnostic test, or if a fatal failure is detected during
operation.
BLINKING This LED is BLINKING during diagnostics, or to indicate special operating conditions. *
LAN ONLINE ON This LED is ON when the Ethernet Interface is connected to the Ethernet network and is
ready to communicate.
OFF This LED is OFF when:
- the Ethernet Interface is not communicating in the network due to disconnection or
disruption of the cable.
- the Ethernet Interface has malfunctioned.
- the Ethernet Interface has been commanded not to enter the network.
BLINKING This LED is BLINKING when the Ethernet Interface is transferring data on the network
or, to indicate special operating conditions. *
SERIAL ACTIVE OFF This LED is OFF during inactivity at the RS-485 serial port.
BLINKING This LED is BLINKING during data transfer at the RS-485 serial port, or to indicate special
operation conditions. *
STATUS OK ON This LED is ON when the module is operating without exception conditions.
OFF This LED is OFF if the Ethernet Interface detects an event (exception condition) during
operation that requires supervisory attention. In this case, refer to the PLC Fault Table for
further information, as described in the Troubleshooting chapter of the User’s manual.
BLINKING This LED is BLINKING during special operating conditions

Special operating conditions are indicated by multiple LEDs blinking in unison:
- During the Software Load state, all LEDs blink in unison.
- During the Waiting for IP Address state, the MODULE OK and STATUS LEDs blink in unison.
- During the Maintenance state, the MODULE OK and SERIAL ACTIVE LEDs blink in unison.
Restart Pushbutton
The Restart button serves four functions: LED test,
restart, restart and enter Software Load state, and
restart and enter Maintenance state. These four
functions behave similarly in all states except for the
Software Load state. While in this state, pressing the
pushbutton will cause an immediate restart into the
Operational state (without performing the LED test)
if the software in the Ethernet Interface has not been
corrupted or erased. If the software has been
corrupted or erased, pressing the pushbutton will
cause an immediate restart back into the Software
Load state. Use a pointed tool to press the Restart
pushbutton.
LED Test: Any time the Restart pushbutton is releaed
all the LEDs flash ON. You should visually verify that all
the LEDs go OFF and ON at this time. Then the Inter face performs either a
restart, a restart and enter Soft ware Load state, or a restart and enter Maintenance
state, depending on the duration that you press the
pushbutton.
Restart: Pressing the Restart pushbutton
momentarily (less than 5 seconds) requests a restart of
the Ethernet Interface. When the Restart pushbutton
