LED Condition
Table
The table that follows describes the island bus condition(s) communicated by the
LEDs, and the colors and blink patterns used to indicate each condition. As you refer
to the table, keep in mind the following:
It is assumed that the POWER LED is on continuously, indicating that the NIM is
receiving adequate power. If the POWER LED is off, logic power to the NIM is off
or insufficient.
Individual blinks are approximately 200 ms. There is a one-second interval
between blink sequences. Please note the following:
blinking—blinks steadily, alternating between 200 ms on and 200 ms off.
blink 1—blinks once (200 ms), then 1 second off.
blink 2—blinks twice (200 ms on, 200 ms off, 200 ms on), then one second off.
blink N—blinks N (some number of) times, then one second off.
If the TEST LED is on, either the Advantys configuration software or an HMI
panel is the master of the island bus. If the TEST LED is off, the fieldbus
master has control of the island bus.
Use the following table to help troubleshoot your system:

Meaning
blink: 2 blink: 2 blink: 2 The island bus is powering up (self test in progress).
off off off The island bus is initializing but is not started or there is no
power present.
blink: 1 off off The island bus has been put in the pre-operational state
by the RST button and is not started.
blink: 3 The NIM is reading the contents of the removable memory
card.
on The NIM is overwriting its Flash memory with the card’s
configuration data (see 1).
off blink: 8 off The contents of the removable memory card is invalid.
blinking
(steady)
off off The NIM is configuring or auto-configuring the island bus,
which is not started.
blink: 3 off off Initialization is complete, the island bus is configured, the
configuration matches—the island bus is not started.
on Auto-configuration data is being written to Flash memory
(see 1).
off blink: 6 off The NIM detects no I/O modules on the island bus.
blink: 3 blink: 3 off Configuration mismatch—non-mandatory or unexpected
modules in the configuration do not match; the island bus
is not started.
blink: 3 blink: 2 off Configuration mismatch—at least one mandatory module
does not match; the island bus is not started.
