Table 4-8. Command and Query Reference (cont)

ALARM_ASSOC?	Alarm Association Query
	Returns alarm output associations for the indicated channel and alarm
	limit.
	ALARM_ASSOC? <channel>,<limit_num>
	<channel>	=	(4 .. 20)
	<limit_num> =		1 2
	Returns the digital output line number associated with the indicated
	alarm limit. An Execution Error is generated if no output is associated
	with this alarm limit, if invalid channel numbers are used, or if limits other
	than 1 or 2 are used.
ALARM_ASSOC_CLR	Clear Alarm Association
	Clear the digital output association for the indicated channel and alarm
	limit.
	ALARM_ASSOC_CLR <channel>,<limit_num>
	<channel>		= (4 .. 20)
	<limit_num> = 1 2
	When the association is cleared, the output pin is left in a high (non-
	alarm) state. If the alarm limit specified is not 1 or 2, or if the channel is
	invalid, an Execution Error is generated.
ALARM_DO_LEVEL	Set Alarm Output Level
	Set or clear the indicated alarm digital output.
	ALARM_DO_LEVEL <DO_line>,<DO_state>
	<DO_line> = (0 .. 3)
	<DO_state>	= 1 (high) 0 (low)
	Alarm outputs 0-3 correspond to channels 0-3, respectively. If the digital
	output line requested is not in the range 0 through 3, an Execution Error
	is generated. If the DO_state specified is not 1 (high) or 0 (low), an
	Execution Error is generated.
ALARM_DO_LEVELS?	Alarm Output State Query
	Returns digital output levels for the four alarm digital outputs.

Returns an integer value representing the state of each of the digital I/O lines. The low order four bits are the status of the alarm digital outputs; 0 indicates line is low (in alarm), and 1 indicates line is high (not in alarm). These lowest four bits correspond to alarm digital outputs 0 through 3, which are permanently associated to channels 0 through 3, respectively. A value of 15 indicates that all alarm outputs are in the non-alarm (high) state.
