Schneider Electric INTERBUS Basic Network Interface Module manual NIM Activity, LEDs

The STB NIB 1010 Basic NIM Module

INTERBUS Data The following table describes the indicated condition(s) and the colors and blink Exchange LEDs patterns that the RC, BA and RD LEDs use to show normal operations and error

conditions for the NIM on an INTERBUS fieldbus.

Label	Pattern	Meaning
BA (green)	on	The module is transmitting data messages on the network.
	off	The module is not transmitting data messages on the network.
RC (green)	on	The island’s incoming bus is correctly connected, and the bus master device is not
		sending a bus reset signal.
	off	The island’s incoming bus is not correctly connected, or the bus master device is sending
		a bus reset signal.
RD (yellow)	on	The island’s outgoing bus is disabled.
	off	The island’s outgoing bus is enabled.

NIM Activity	The table that follows describes the island bus condition(s) communicated by the
LEDs	LEDs, and the colors and blink patterns used to indicate each condition.
RUN (green)		ERR (red)	Meaning
blink 2		blink 2	The island is powering up (self test in progress).
off		off	The island is initializing—it is not started.
blink 1		off	The island has been put in the pre-operational state by the RST button—it is
			not started.
blinking (steady)		off	The NIM is auto-configuring the island bus—the bus is not started.
blink 3		off	Initialization is complete, the island bus is configured, the configuration
			matches, and the bus is not started.
off		blink 6	The NIM detects no STB I/O modules on the island bus.
off		blink 2	Assignment error—the NIM has detected a module assignment error; the
			island bus is not started.
		blink 5	Internal triggering protocol error.
off		blinking	Fatal error. Because of the severity of the error, no further communications
		(steady)	with the island bus are possible and the NIM stops the island. The following
			are fatal errors:
			significant internal error
			module-ID error
			auto-addressing failure
			process image error
			auto-configuration error
			￿island bus management error
			receive/transmit queue software overrun error
on		off	The island bus is operational.
on		blink 3	At least one module does not match—the island bus is operational with a
			configuration mismatch.
blink 4		off	The island bus is stopped—no further communications with the island are
			possible.
off		on	Fatal error—internal failure.
