eX80 Analog I/O Module Diagnostics

LED Diagnostics

Use the combined states of the RUN, ERR, I/O, BS, An and Hn LEDs to diagnose the channel and module status for the BMEAHI0812(H) and BMEAHO0412(C) modules:

LED						Description
RUN	ERR	I/O	BS	A0...An	H0...Hn	Description
OFF	OFF	OFF	OFF	All OFF	All OFF	Module has no power, or has stopped operating.
BLK green	BLK red	BLK red	BLK red & green	All OFF	All OFF	Module is performing self-test on power-up.
OFF	BLK red	OFF	X	All OFF	All OFF	The module is not yet configured, or is in the process of configuring its channels.
ON green	BLK red	X¹	X	X	X	No communication between the output module and the head module. NOTE: The module retains the previous I/O status.
ON green	OFF	OFF	X	ON green	X	Analog channel is operational.
ON green	OFF	OFF	X	OFF	X	Analog channel is disabled.
ON green	ON red	OFF	X	OFF	X	Analog to digital conversion detected error, or power supply detected error on channel.
ON green	OFF	ON red	X	FLK	X	Overflow or underflow error detected on channel.
ON green	OFF	ON red	X	BLK	X	Broken wired detected on input sensor channel or output actuator channel.
ON green	OFF	ON red	X	OFF	X	Calibration error detected on output channel.
ON green	OFF	ON red	X	X	ON red	No response from HART device on channel.
ON green	OFF	OFF	X	X	BS red	A HART device has been detected with a major difference from the device that is configured for the channel.
ON green	OFF	OFF	X	X	FLK red	A HART device has been detected with a minor difference from the device that is configured for the channel.
ON green	OFF	OFF	X	X	ON green	A HART device has been detected that is the same as the device configured for the channel, or a device with a detected major or minor difference has been accepted.
ON green	OFF	OFF	X	X	BLK green	The HART channel is connecting to a device.
ON green	OFF	OFF	X	X	OFF	HART communication disabled for the channel.
BLK green	OFF	OFF	BLK green	X	X	The I/O module is downloading firmware.
X	X	X	OFF	X	X	The module has not been assigned an IP address.
X	X	X	BLK green	X	X	The module has no established EIP Forward Open connections, but has an IP address.
X	X	X	ON green	X	X	The module has established an Ethernet connection.
X	X	X	BLK red	X	X	The module Ethernet connection has timed out. This is cleared only when the timed out connection is re-established or if the module is reset.
OFF	X	X	ON red	X	X	The module has detected that its IP address is already in use.

ON	LED is steady on.
OFF	LED is off.
FLK	Flickering: ON for 50 ms, OFF for 50 ms, repeat.
BLK	Blinking: ON for 200 ms, OFF for 200 ms, repeat.
BS	Blinking Sequence: ON for 200 ms, OFF for 1,200 ms, repeat.
X	This LED is not used in determining the channel or module status.
